What do you mean?  A generator or an alternator?  Given enough power
from mechanical source (wind) to overpower the resistance of the
generator it would produce current.  Most of them, except for brush
dynamos, will produce AC which needs to be rectified back to DC and
regulated at a current a little above that of the battery.  Whether it
is a bicycle or wind generator or your auto/moto charging circuit, isn't
it how it all works?
Now if you put a 3' fan in a truck alternator and a 100Amph battery I
suspect it would take a hurricane to get it moving.

This all started from the OP stating that FMIT (on all debian main
rep's) records sound without any audio inputs in the system.

I know a chap who found about that the hard way when he tried to get
something from nothing by charging a battery from a generator which he
turned by having a fan connected to it. :)

He didn't get electrocuted or anything, the fan abruptly stops turning.

That's not what I mean.  Hook an induction motor to utility power and
drive it above synchonous speed.  It will power *to* the network.

When you put DC current through the field of an induction motor to brake
it you are also using it as a generator.  It's just that all the power
gets dissipated in the armature.

Yes, there is that exception, they need an excitation current, true, but 
in that case they make excellent brakes as they don't like spinning

enough dc current you can come pretty close to stopping them dead in

If debian identify's it as a microphone, take it up with debian. Udev has 
been know to goose the moose before.  File a bug if that is the actual 
case.  And yes, that "speaker" might be a piezo beeper, but with the 
right amps looking at it, it will make a halfway decent microphone. This 
is paranoid scary given some of the tricks the NSA has pulled off. But 
commercial intercoms have been using a small speaker as the talkback 
microphone for at least the 70 years that I have been chasing electrons 
for a living.  That dates back to well before the transistor was 
invented.

And yes, I am now an old fart of 82.  But I was an electronics geek well 
before the term became popular. I quit school in '48, and started fixing 
them newfangled things called tv's for a living. I finished off the last 
18 years I worked by having a nameplate on my office door that said I 
was the Chief Engineer, w/o ever going back to school unless it was as 
the teacher. Along the way I collected a 1st phone ticket from the FCC, 
and a CET from a small town college prof in Nebraska, turning in the 
test in about 45 minutes. He had been teaching students for that 
certification for several years. I was the first to walk in, hand him 
the 20 to take it, and passed it. Its normally allowed 4 hours. IMO? He 
had no business teaching it if in 5 years or so, none of his students 
had passed it.

Induction motors can function as generators.  You just need to connect
them to an appropriate AC source and drive them above synchronous speed.

No, due to the absence of all the other parts needed deliver any signals
generated by the speaker back to the computer (not to mention that it
would make a very poor microphone).

So, are you saying the standard motherboard beeper/speaker (the one that
beeps when you hit too many keys at once or that bios is telling you I
am booting up ... any minute now bepp) is a microphone that feeds
sound back into the system and mysteriously debian is allowing it to be

Very simple. With the glaring exception of the modern AC induction motor 
that in 99% of the stuff we buy, ANY other generator can also be used as 
a motor, including the ultra cheap electret condenser microphones, ditto 
any speaker, including the peizo tweeters, is also a microphone.  Its

I don't know about clay, it sounds more probable that prehistoric voices
affected reflected light to the universe and its returning reflection
may incorporate data that when decoded may reveal those voices.  In
other words some prehistoric sounds may not be heard yet.

Back to shanity, how does a microphone produce an electrical wave that
can be translated into sound and how a wave may take the form of
electrical current that produces sound through a speaker?  It is not
like particle acceleration science, it is stuff that many guitarists now
and most guitar repair-persons know.  The question that is relevant to
the list is why would a security minded system allow such noise to be
communicated?  Whatever that noise is, it shouldn't be there, as if it
is there it can be anywhere.

Your appeal for case dismissal is denied!

By the way, it takes about 3' to download FMIT or something similar,
lower the db cutoffs and increase the frequency range and if it is not
there we may have something to compare.  I don't readily have a laptop
with a battery strong enough to stay on without AC, I assume they have
less electrical noise.  My noise is around 21,5KHz-23KHz with an
emphasis around 22,2...  which can't be random, but abrupt vibrations on
the case register within that noise wave.  We are in the 220v/50hz
world, so it would be interesting what the noise freq. is on 110v/60Hz

In case this wasn't clear: we're imagining clay being fashioned upon a
potter's wheel, and the striations that occur in the clay as it is
molded (which might possibly produce, according to Charpak's conjecture,
a sort of analog audio recording of ambient sounds in the finished
product, e.g.--"Hey Mosche, got any more of that Egyptian beer we were

Re: No sound-inputs but sound recording FMIT

[GiaThnYgeia]

https://packages.debian.org/jessie/fmit
https://packages.debian.org/stretch/fmit

Here are the two current versions of it and I like it because it gives a
little more control in tuning out noise and concentrate in what I want
to measure.

It is most probably electrical noise and fluctuations of voltage and/or
frequency, which may get amplified to look like an unstable wave form.

This part may be understood enough to leave it to the sound experts.

What is interesting is that a mechanical vibration may actually cause
electrical contacts on the whole system to create an instability within
that electrical noise.  One does not need to be a sound physicist to
translate this into an effective microphone.  How many pc's don't have
panels that act as drums and amplify noise and transform noise into a
mechanical vibration?

No, there is no onboard mic, there are only two audio inputs front and
back, and as I said trying this in 2 other systems with different debian
builds had similar results (some noise registering and affected by
abrupt vibration).

Yes I have pavucontrol installed, pulseaudio and utils.

PS  Suddenly, the noises in one's head that nobody else hears are
recorded by one's only true friend, the PC   :)) :)))

Since you guys now have hijacked the thread it is ok for me to continue

On my second try to address a related issue I "forwarded" to the list
the previous text as part of a reference with a new subject.  As I use a
non-html editor, txt comes in and txt comes out, I forget that the
headers are hidden, but never thought they were included in forward,
only in replies.  It is good to know that mozilla in providing with a
clean email gui does such things.
Also if you use reply instead of reply-all or reply-list the headers
that are picked up "by the list" are threading the messages.  So it is
partly the list-laundering activity that creates all the confusion.
I'm willing to bet that in interpersonal exchange some of those messages
wouldn't be threaded.  But I've seen it happen both ways, Re:
same-subject unthreaded and Re: different-subject threaded.  So it must
have to do with some mailing systems stripping headers and some that
don't do it, and effective stripping goes two ways.

Come to think of it, do newsgroups still exist?

Because hitting New means you have to put in the To address, but hitting
Reply means the address is already there and you can just start typing

Yes, this apparently is enough of a convenience factor to affect

I was interested in your mainboard - perhaps it has integrated mic.

Do you have pavucontrol installed? Go to input devices and mute the mic

No sound-inputs but sound recording FMIT

[GiaThnYgeia]

I don't see how the previous got linked to a previous thread so I am
reposting with additional clarification.

OK, I did some testing on an other machine with a testing installation,
downloaded FMIT (an instrument tuner that will pickup audio input/analog
and tell you all kinds of stuff about the wave that is fed).
Same exact behavior, hardware only lists two audio inputs and are both
unplugged.  The lower the db threshold for sound recording the more
apparent the sound becomes.  Each knock on the box shows corresponding
amplification of that noise.

Ok, so I picked up 2-3 live debian based USB sticks I have.  I plugged
then in to 3 different machines, downloaded FMIT and run it.  Similar
results.  So it has nothing to do with my configuration of stuff.  I say
if some software is picking up sound from your environment and records
it when no inputs are plugged in I would call this a "security" issue
not a malfunction.

What is there MORE to post so it can be reproduced?  Blank live debian
installations adding FMIT in 3 machines Jessie + Stretch (one on UPS,
one on mains-plug, on laptop) if you allow it to see a wide spectrum of
frequencies it records noise (mostly hi-freq) and only hardware inputs
are unplugged.  Where is the noise coming from?

It probably has nothing to do with the program itself but its
dependencies and some code feeding in wrong data as audio input.  But it
is actual sound

True, although someone who doesn't know that hitting Reply on an
existing message threads the reply in under the existing message is
unlikely to even know what message headers are, much less know how to do
this. (Or be using a mail client which does permit that.)

To clarify this, since many people in the modern era apparently don't
realize it:

Changing the Subject line on a reply E-mail does not make that E-mail be
the first mail in a new thread. (Although some E-mail clients, such as
Outlook, will probably display it as if it was.)

In order to start a new thread, you have to create the E-mail from
scratch, e.g. by using a "New Mail" button or the equivalent. Creating
an E-mail by replying to an existing message puts the new message into
an existing thread, even if the Subject line is changed.

Re: Crackling sound from usb sound device

[Klaus Pieper]

Does it crackle, when the USB storage device and the USB video device
are unplugged? Were the USB storage and video devices plugged to other
USB slots in the past?



Hi Ralf,
changed the slot for the audio device, now it works.
Thanks for the hint

Crackling sound from usb sound device

[Klaus Pieper]

Hi,

I have been using an external dac over usb for some months. Since about 
two weeks sometimes sound is distorted (irregualar crackles, which 
usually diappear after closing and reopening the application, i.e. mpd, 
xine, rhythmbox or a stream from firefox, some times).


I am under the impression that this happens since a kernel upgrade a 
week ago.


The message cannot get freq at ep 0x1 appeared in the logs before. 
Where does it come from and what does it mean?


Any ideas?

Thanks
Klaus

No IRQ issue in the sense of, no other device does share USB IRQs, but

The video device is the builtin camera of the Thinkpad.
I unplugged the USB CD and got the same behaviour (reboot, while mpd is 
playing, get the crackle after reboot).


No hardware changes whatsoever in the last weeks.

 Alternatively you can click on the arrows to the right of the device drop

First, Audacity shows no source bar because it only sees one source,
line in.

Second, as Jonathon suggested, the proper selections must be made in
Audacity's Edit/Preferences/Audio I/O window.  This is not obvious as
when first loaded ALSA: HDA NVidia AD198x Analog (hw:0,0) is already
selected for both input and output.  This works for input but not for
output.  Other choices are offered but ultimately found ALSA: default
works for both input and output.

Third, getting this far does not guarantee either authe Alsamixer man
page is necessary.  When the correct capture channel is selected (There
are at least three) and the proper output volumes are set and not muted
you are in business.

When all this is done it works very nicely.  Having only line input is
okay for me as the line is from my stereo system which includes phono,
tape, cd, radio and tv.  Still it is annoying not to be able to capture
directly from the systems optical drive.

sound and no sound

[chadjensen]

Hello all,

I have a machine. One user logs in (using gnome) and has sound. The
second user logs in (also using gnome) and does not. When the second
user double-clicks on the volume applet he gets the following error:

The volume control did not find any elements and/or devices to
control. This means that either you don't have the right GStreamer

plugins installed, or that you don't have a sound card configured.

You can remove the volume control from the panel by right-clicking the
speaker icon on the panel and selecting Remove from panel from the
menu.

Anyone have any advice on how to track down this problem? I figure it
has to be something in the second users' environment or dot files, but

I haven't a clue where to start.


Thanks for your help,

I had this no-sound problem (sans the error message) on a sarge system
that was never solved.  As Greg suggests, check what processes the user
left running (ps -ef |grep username) and see if esound is locked to
another user (ps -ef |grep esd , then iirc, check the sockets in /tmp
for username).

Good luck,

I see a similar problem in etch on the family machine. Whoever logs in
first gets system sounds. if you then switch to and log in another
user, that user gets no system sounds. other sound works fine for all
users, just the system sounds. I notice that the esd socket is owned
by whoever first logged in, but it has very liberal permissions so
that anyone should be able to access the server. Not sure how to fix
this. I tried running esd before starting up gdm so that the socket
perms were root:root rwxrwxrwx but no luck.

Oh yeah, and:
- both users are in the audio group
- permissions on /dev/dsp are crw-rw, and owned by root:audio
- contents of .xession-errors for second user contain the following:
 /dev/dsp: Permission denied
 *** (gnome-session:4512): WARNING **: Esound failed to start.

I don't know why esound would fail to start if both users are in the 
audio group.

Re: Sound issue: slow sound?

[Bob Vloon]

Hi Dennis,

 Recently, sound started misbehaving. First, sound would not only fail
 to play, any application that called for use of sound would freeze,
 only to die (in the case of Totem) on a kill -9. A reboot later, and it
 now does play, but it sounds like a 33 rpm record knocked down to 16
 rpm.

Do you use some sound system like aRts or Jack? It sounds (haha :) more like
a problem of such a system than of ALSA / OSS.

Regards,

  Bob

Sound issue: slow sound?

[Dennis Carr]

OK, weirdness here.

Running Sarge, all updates current. Only thing out of distro is OOo 2.0
from backports. Sound card uses snd-cmipci.

Recently, sound started misbehaving. First, sound would not only fail
to play, any application that called for use of sound would freeze,
only to die (in the case of Totem) on a kill -9. A reboot later, and it
now does play, but it sounds like a 33 rpm record knocked down to 16

Since finding this problem, I've tried an apt-get --reinstall of
alsa-base, a --purge (and subsequent installation) of all alsa-related
items in my system (-base, -oss (which I think is required by xmms),
-utils, and mixergui), and likewise, a dpkg-reconfigure of everything
but alsamixergui - and none of these has helped.

What am I missing, where should I look for errors, and what more
information is needed for this problem?

Re: Oh, NO! Not that same No Sound question again... (Sound now working)

[listcomm]

Just in case anyone can use the two bits of information I turned up...

Having tried everything I could find to try to make the OSS
(i810_audio) driver work, based on what little information I
could find about it in the docs or online , I finally gave up
and compiled and installed Alsa drivers for my 2.4.18-bf2.4 kernel.

Then, by using alsamixer and unmuting the usual suspects, I was able
to
get sound working.

None of the other mixers I had previously installed (aumix, kmix,
and xamixer2 (which crashed completely)) would enable sound to work.
One point of interest was that the alsamixer GUI has a slider for
headphone, which none of the other mixers have, and which was what
I discovered by trial and error to be what controlled the sound output
jack on my MB.

I'm wondering if the i810_audio OSS driver was really at fault or if
the
mixers I was using with it were just incapable of controlling the
output
to the jack on my motherboard (and more significantly, how one could
make such a determination).  But, I gather there's no way do diagnose
such things, so I guess I'll just Move On.

I am disappointed, saddened, troubled, disheartened, and discouraged
(did
I miss any?) that it was only possible to get this working by trial
and error.  Auto mechanics discriminate between real mechanics who
troubleshoot problems and fix them, and parts replacers who, just
keep on replacing things (and charging the customer for it)
until something works.  The latter are generally considered
by their cow orkers to be subhumans at best.  If there's no way
to actually troubleshoot these problems, and we have to resort to
swapping
modules in and out until something works, we're no better than the
parts replacers.

IIRC, the 2.4.18-bf2.4 is one of the kernel used in the Woody boot
floppy, so for space restriction and compatibility measures, his scope
is only to have a bare system up and running, it doesn't have all the
modules a default kernel sports.

You can really troubleshoot the problems, the sources are out there,
you only need the HW documentation on how your hardware works, but
usually HW vendors don't cooperate, and here i'm not talking about
asking for HW drivers, but only HW specs or documentations.

Some cd player software simply sends commands to the drive to play the
cd.  This requires the drive's audio-out to be connected to the sound
card's audio-in.

The other option is for the software to extract the data from the cd,
process it, and write it out to the sound card.  This does not require
a direct audio connected between the two.  It also requires more
complex software processing, and as a result more CPU and bus
bandwidth to play.

 driver to /etc/modules . In my /etc/modules I have ac97_codec, soundcore,
 pci-scan, tulip all on their own line. That causes those modules to load
 at boot up. HTH Don

Just tried it, but as I already expected, this is no cure.

Look, the problem is not that Linux does not try to load module ymfpci:
it tries very hard! I find dozens of failed attempts reported in
/var/log/syslog and /var/log/messages, from the very start of the boot
sequence, when the hotplug subsystem loads drivers for all devices present.
The problem is that, with ymfpci, every attempt fails with the following
sequence of messages, which is also the result of entering 'modprobe ymfpci'
on the command line:

PCI: Found IRQ 9 for device 00:09.0

ymfpci: YMF744 at 0xfedf8000 IRQ 9

/lib/modules/2.4.20-hetkukel-1/kernel/drivers/sound/ymfpci.o: init_module: No such 
device

/lib/modules/2.4.20-hetkukel-1/kernel/drivers/sound/ymfpci.o: insmod 
/lib/modules/2.4.20-hetkukel-1/kernel/drivers/sound/ymfpci.o failed

/lib/modules/2.4.20-hetkukel-1/kernel/drivers/sound/ymfpci.o: insmod ymfpci failed

Hint: insmod errors can be caused by incorrect module parameters, including invalid IO 
or IRQ parameters.

  You may find more information in syslog or the output from dmesg


Somehow, Windows is to blame, for this *only* happens after a 'warm reboot'
from Windows. After a power-on boot or a reboot from Linux there is only one
line in the logs about ymfpci, effectively saying that the module has been
loaded and is ready for its job.

 It has been a number of years since I had Windows and Linux running 
 together but I do recall that I had to disable a bios setting that 
 allowed the OS (Windows) to control IRQs (disable Plug  Play OS).  If 
 you hard set the IRQs in the bios both Windows and Linux should use the 
 same ones.

Plug  Play OS *is* disabled in the BIOS. The BIOS allows me to hard set
IRQs and IO ports for only a few devices, the serial and parallel ports as
far as I remember, not for the sound card anyway. But, hard set or not, the
IRQ and other hardware settings for the sound card drivers *are* the same in
Windows and Linux. I carefully checked that, and reported the values in my
original message.

So  I don't think you just provided the key to a solution.

Thanks for your follow-up though!

sound: loading of sound driver fails after reboot from Windows

[Ben Kal]

Hi folks,

Do some of you know more about the following inconvenience I have
with sound on my Linux machine:
  sound works fine if I boot directly into Linux after power-on,
   and if I reboot from Linux back into Linux;
  sound does not work at all after rebooting into Linux from Windows.
In Windows sound works under all circumstances.
(Please don't tell me not to use Windows. I don't, but my children do).

I have found that the immediate cause of the problem is that Linux
is unable to load the driver for the sound card if Windows has been
in use since the last power-on. Knowing this does not help much:
attempts to load the driver with modprobe or insmod simply fail.

This exact phenomenon is not described in the documentation about sound
on my machine, nor could I find a problem story like this on the web.

What I would like to know is:
- can something be done about this, in Windows and/or Linux,
  or is it an inconvenience one has to live with?
- who is to blame, Windows for leaving the sound card in a messy state
  or Linux for not being able to deal with the state of the card?

I already know that:
- one has to disable 'Plug and Play' in the BIOS;
  it IS disabled
- one has to make sure that iomem, ioports and IRQ settings for the
  sound chip have to be the same in Windows and Linux;
  they ARE the same, as follows:
iomem : FEDF8000-FEDF
ioport: FCC0-FCFF
ioport: FC8C-FC8F
IRQ   : 9


Some other specifics of my machine:
  make and model: Sony VAIO PCG-F807K (it is a laptop)
  kernel: Linux 2.4.20
  Debian release: basically woody, but a lot of things upgraded to 'unstable'
  sound chip: YMF-744B| (especially X and GNOME)
  sound driver  : ymfpci.o, dependent upon: ac97_codec.o


The most revealing (error) messages are the following ones,
written to /var/log/syslog during a 'reboot-from-Windows':

from the 'hotplug' phase of booting:

  /etc/hotplug/pci.agent: pcimodules is scanning more than 00:00.0 ...
  insmod: Using /lib/modules/2.4.20-hetkukel-1/kernel/drivers/sound/soundcore.o
  insmod: Symbol version prefix ''
  insmod: Using /lib/modules/2.4.20-hetkukel-1/kernel/drivers/sound/ac97_codec.o
  insmod: Using /lib/modules/2.4.20-hetkukel-1/kernel/drivers/sound/ymfpci.o
  insmod: /lib/modules/2.4.20-hetkukel-1/kernel/drivers/sound/ymfpci.o: init_module: 
No such device
  insmod: Hint: insmod errors can be caused by incorrect module parameters, including 
invalid IO or IRQ parameters.   You may find more information in syslog or the 
output from dmesg
  insmod: /lib/modules/2.4.20-hetkukel-1/kernel/drivers/sound/ymfpci.o: insmod 
/lib/modules/2.4.20-hetkukel-1/kernel/drivers/sound/ymfpci.o failed
  insmod: /lib/modules/2.4.20-hetkukel-1/kernel/drivers/sound/ymfpci.o: insmod ymfpci 
failed
  /etc/hotplug/pci.agent: ... can't load module ymfpci
  /etc/hotplug/pci.agent: missing kernel or user mode driver ymfpci 

later on, when initializing PCI bus devices (device 00:09.0 is the sound card):

  kernel: PCI: Enabling device 00:09.0 ( - 0003)
  kernel: PCI: Found IRQ 9 for device 00:09.0
  kernel: PCI: Setting latency timer of device 00:09.0 to 64
  kernel: ymfpci: YMF744 at 0xfedf8000 IRQ 9
  kernel: ymfpci_codec_ready: codec 0 is not ready [0x]


Other sound-related error messages in various places look to me as
merely being the consequence of the ac97_codec and ymfpci modules
not being loaded.


Any information on similar experiences or hints for further investigation
will be appreciated.

Regards,
Ben Kal

sound but no sound

[Rick Pasotto]

Sound is working in that I get gnome desktop sound events but other
programs like xmms or mp3blaster or freeamp just hang.

I'm current on testing (sid). Sound used to work properly so some
upgrade changed something but I have no clue what.

What do I have set wrong? Where do I check?

GNOME uses esound to allow multiple programs to send audio data.  You need to 
enable esd support in these other programs.

How do I do that? Is that a gnome setting or does each individual

It is per app.  In xmms look for the output plugin control.  You may need to

ECS K7S5A SIS7012 Linux Onboard Sound: Erfolg! (War: Sound unter Debian - und nun?)

[Frank Blatzheim]

Hallo Allerseits!

nachdem ich nun noch einmal eine geraume Zeit mit dem Onboard Sound
meines Elitegroup K7S5A Motherboards verbracht habe kann ich einen
Erfolg verbuchen!

Alle Versuche den SIS 7012 Chipsatz mit den Treibern von SIS selbst oder
den ac97_codec und i810_audio des Kernels 2.4.18 waren ohne Erfolg. Erst
als ich einen neuen Kernel gebaut hatte, der Sound als Modules enthielt
kam ich langsam weiter:

M Sound card support
M   Intel ICH (i8xx) audio support
M   OSS sound modules
M   MPU-401 support (NOT for SB16)

Ansich sind die Module für i8xx und MPU-401 für den späteren Erfolg
überflüssig, aber weil es so klappt schreibe ich den kompletten Weg auf.
Nach dem Installieren des neuen Kernels incl. Lilo-Aufruf und Reboot
habe ich mir die letzte Version des ALSA Soundpaketes als Sources
geholt:

alsa-driver-0.9.0rc3.tar.bz2
alsa-utils-0.9.0rc3.tar.bz2
alsa-lib-0.9.0rc3.tar.bz2

Zuerst alsa-driver entpackt, danach ./configure --with-sequencer=yes
aufgerufen, anschliessend make install und ./snddevices umd die nötigen
Devices zu erzeugen.

Als Nächstes müssen einige Anpassungen in /etc/modules.conf gemacht
werden. Da Debian das aber selbst mit dem modutils Paket verwaltet habe
ich eine Datei /etc/modutils/alsa angelegt:

# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-intel8x0

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0

# OSS/Free portion - card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

Danach update-modules aufgerufen damit diese Einträge automatisch in der
modules.conf landen. Nun wird das alsa-utils Paket entpackt, mit
./configure eingerichtet und mit make install installiert. Danach steht
auch der benötigte amixer zur Verfügung mit dem man die per Default
stummgeschalteten Sounddevices erst einmal aktiv schalten muss. Ehrlich
gesagt bin ich aus man amixer nicht so richtig schlau geworden, auch
vermisste ich einen Befehl um mal eben nur die Devices einzuschalten.
Also habe ich einfach ein kleines Script benutzt:

/usr/local/bin/alsa-on
#!/bin/sh
amixer -c 0 set 'Master',0 unmute
amixer -c 0 set 'Master Mono',0 unmute
amixer -c 0 set '3D Control - Center',0 unmute
amixer -c 0 set '3D Control - Depth',0 unmute
amixer -c 0 set '3D Control - Switch',0 unmute
amixer -c 0 set 'PCM',0 unmute
amixer -c 0 set 'Line',0 unmute
amixer -c 0 set 'CD',0 unmute
amixer -c 0 set 'Mic',0 unmute
amixer -c 0 set 'Mic Boost (+20dB)',0 unmute
amixer -c 0 set 'Video',0 unmute
amixer -c 0 set 'Phone',0 unmute
amixer -c 0 set 'PC Speaker',0 unmute
amixer -c 0 set 'Aux',0 unmute
amixer -c 0 set 'Capture',0 unmute
amixer -c 0 set 'Mix',0 unmute
amixer -c 0 set 'Mix Mono',0 unmute
amixer -c 0 set 'External Amplifier Power Down',0 unmute

Ja, das kann man in einer Schleife viel besser machen. Nachdem ich
festgestellt hatte, das es nur die halbe Miete war und ich nun auch noch
den Pegel für jeden Ausgang aufdrehen muss reichte es mir und ich nam
das Konsolen-Util alsamixer, mit dem ich einfach alle verfügbaren Pegel
auf 75% stellte.

Ein kurzer Versuch mit aplay irgendein.wav ergab Sound! Ich war happy.
Als User ging es wieder nicht, weshalb ich brutal einfach /dev/mixer und
/dev/dsp mit chmod 666 allgemein öffnete. Alles wie gesagt quick 
dirty. Nächster Test ob ein als User gestartetes X11 mit Enlightenment
auch Sound hat. Dazu in die ~/.xinitrc eingefügt:

[...]
esd -nobeeps /dev/null 

startx gemacht, in Enlightenment apply sound eingeschaltet und -
nichts :-(. Aber immerhin keine Fehlermeldung. Da ich Gkrellm
installiert habe, das IMHO genialste X11-Tool überhaupt, und in diesem
wiederum ein Volume-Plugin habe ich in diesem gerade nachkonfiguriert:

Mixer-Devices
[X]Vol [X]PCM [X]CD

Options
[X] Mute all mixer devices we control
[X] Open/close mixer device
[X] Save volumes on exit und restore them on startup

Nun noch die Schieberegler im Gkrellm-Volume-Plugin aufgedreht und
voila: Sound!

Unter X11 geht nun play oder aplay nicht mehr weil esd die /dev/dsp etc.
exclusiv belegt. Das ist aber auch kein Beinbruch, stattdessen geht
esdplay.

Was fehlt noch:
Das Ingangbringen des Midi-Teils. Dieser lässt sich im Bios explzit mit
einem (beliebigen)IRQ und einer Portadresse von 0x300h oder 0x330h
konfigurieren. Unter linux habe ich bisher aber noch nichts gefunden was
daruaf aufsetzt. Während ich jetzt *.au. *.wav und mit mpg123 auch *.mp3
abspielen kann ergibt ein Versuch mit *.mid nur eine Fehlermeldung beim
Versuch auf snd-rawmidi zu schreiben. Alle Tipps sind sehr willkommen.


Grüsse
Frank

AudioWave 16 AISA sound card, and sound-card IDE in general

[Will Lowe]

I'm buying an old 486 from a friend real cheap to use as a mail server.
The IDE card in it can only handle two ide devices,  the machine has two
hard drives,  an IDE cd-rom,  and an IDE tape drive.

THe latter two he's been running from the sound card ide interface ... is
it possible to do this in Linux?  I moved my cdrom on my other machine off
my soundblaster and onto the main IDE controller,  but that's not an
option in this 486 because the IDE card is full.

Also,  the sound card is an Audiowave 16 AISP (made by sony).  The
audiowave web page (found via altavista) says that the newer version,  the
AudioWave PCI something-or-other,  is SoundBlaster 16 compat. ... anyone
tried using the Audiowave 16 AISP under linux?  I don't really need it to
do sound (although if it does,  so much the better),  but I'm going to
need it for a while to do IDE stuff.


Will
