Subject: Linux Sound Systems Overview?!?!?!
Reply-To: [EMAIL PROTECTED]
Date: Sat, 02 Dec 2000 00:46:53 GMT
Does anyone know of any documentation which describes the various
types of sound systems for Linux and how they inter-operate?
I have read the Sound and Sound-Playing how-to's and that is not what
I'm asking about.
I don't have all the information so I may not use the correct
terminology BUT here is a description of what I'm trying to resolve.
Different Linux sound applications and utilities seem to talk to the
sound hardware in different ways that are not always mutually
compliant. So far I have un-officially identified the following sound
systems:
1) Linux Native
2) New Linux Native
3) OSS
4) ALSA (?)
5) ESD
The "Linux Native" system worked fine with my old Sound Blaster Pro.
It utilized /dev/audio and /dev/sndstat and all the programs I wanted
to use lived comfortably with it.
My new system uses an integrated C-Media CMI8738 on a PCChips M599LMR
mother board. Both the add-on driver (for older kernel versions) and
the current included driver (cmpci.o) seem NOT to use the traditional
/dev/audio and /dev/sndstat BUT the /dev/dsp interface. This causes a
lot of trouble with some applications, and some I have not been able
to get working at all.
I don't understand how the OSS, ALSA(?) and ESD systems fit into the
picture but it has been causing me a lot of trouble lately. I tried
to get XMMS running on my system BUT it will not play a peep unless I
select the ESD option and load esd ... but then nothing else works
while I do this. The Enlightenment Sound Daemon (ESD) loads, plays a
scale of notes and xmms works PERFECTLY. I have to unload ESD before
speak freely or realplayer or any other of my "native" applications
will work.
Any way, I am looking to collect enough information to try and get
sound working co-operatively on my system and have access to all the
applications I am looking for.
Thanks in advance for any comments, pointers and insight you can
supply to this effort.

Date: Sat, 02 Dec 2000 00:57:47 GMT
Linux doesn't have real PnP support in 2.2 (2.4 will). You can configure
PnP hardware by using pnpdump and isapnp (see man pages), however this is
really just a hack. What the setting is supposed to do is configure the
resources of PnP cards in the BIOS, so that a PnP-compliant OS isn't
needed. On my system I have had success using the system with PnP OS
set to no with a PnP ISA sound card...the IRQ and DMA were set by the
BIOS, and I just set it up manually without needing to bother with
isapnp. So it might help setting it to no. But if you need to can't get
the sound card to work without PnP on (I have used PCI sound cards
successfully with PnP off, but I have no experience with the SB Live),
you may just have to deal with isapnp, or use the 2.4 test kernel (IMHO,
very stable), which has real PnP support built in.

Thanks for all the info. I think i will try and save a copy of all my
config files in etc, is there anywhere else that has important config
file? THen I guess format my hardrive and reinstall from scratch, using
my saved configs as reference to help me through getting the same set up
back. If I format the hardrive with all my linux info is there any
reason why i shouldn't boot linux from my cdrom?

You _may_ need to compile a custom kernel in order to cope with this;
I'm not certain what Red Hat has "out of the box" as its default.
That in effect means that you may indeed need to "reinstall Linux,"
with regard to _Linux, The Kernel._
It should _only_ be the kernel that you need fiddle with; user space
does not change, so that you do _not_ need to pop in a CD and
reinstall libraries, programs, or such.

Hope your specific pieces of hardware are *NOT* listed as Winmodems
there. If they are, sell the modem(s) to a stupid person and go buy a
Real Modem. A Real Modem is usually one that is external and plugs into
the 9-pin serial port. Most PCs sold today come with Winmodems because
those are very cheap to make.

If you can find a multi-port parallel card, chances are good that it
works with Linux. The original IBM PC standard specified only 3
parallel ports, but putting another one in should just be a matter of
having a free IRQ and I/O range. You may have to pass these numbers to
the parport_pc module for all the parallel ports to be recognized.
BTW, printing will be somewhat slow if all 4 printers are in use at
once. "man tunelp" to try and speed it up a bit, but I'd see about an
Ethernet interface if you need more speed.

http://linuxdoc.org/HOWTO/CD-Writing-HOWTO.html
and pay attention to the section about "IDE CD-RWs". It's been possible
to use an IDE CD-R(W) with Linux for quite some time now (1.5 years,
maybe more). The SCSI bias shown in cdrecord's docs comes from: 1)
cdrecord's author has a low opinion of IDE drives 2) there's no "native"
Linux driver for IDE CD-RWs.
Search this NG ( http://deja.com/home_ps.shtml ) for my name and keyword
"CD-R" to find a bunch of messages dealing with this topic if the HOWTO
doesn't quite do it for you.

Check your termination, check your cables, and $DEITY help you if that
2G drive and/or disk was ever banged on or dropped more than 6 inches.
I think it might be a mechanical problem--can you borrow a known good 2G
JAZ disk from somewhere and try that disk in your drive? If it works,
your disk is most likely toast. If it gets ejected, your drive is most
likely toast.
Oh yes, the card should probably be set to "auto-terminate" or "no
terminate" if you have both external and internal devices on the bus.
If the internal drive is the last device on its end of the bus,
terminate it.

This "PnP support" is one of the less useful things in the new kernel. Very few
modern boards have ISA slots anymore and hopefully, the bus itself will soon
die a horrible death, taking with it the rest of the obsolete junk we still have
in our computers (floppy drives, serial and parallel ports come to mind,
there's probably more). I think valuable programming resources shouldn't even
have been spent supporting the obsolete hack known as ISA PnP, while a ready
solution (isapnptools) has been available for many years.

Hi
I've been trying to get my USB mouse to work under LM7.2. so far i've had
no luck.
The mouse gets detected during the install and boot but i get no response
from
it. I had to use an old PS/2 mouse during install to be able to do anything
and in my attempts to get the USB mouse working. I tried using drakconf to
change it to USB but it just changes back to the PS/2 one. And of late even
the PS/2 mouse is not responding. I've tried editing my XF86Config to get
the mosue working but i get "No such device" when it tries to accsess the
device (/dev/usbmouse). the symlink is there, pointing to /dev/input/mouse0
(this was done during install by the installer).
Can anyone help me with this?
thanks in advance

The usual answer is that even if an o/s is pnp aware, it won't hurt to
run it on "not" aware. Most of the time "not" is preferable for linux,
and you should probably set it there unless you have a reason not to.
Being that your modem is ISA though, ISA pnp is not set up by the system
bios, and is instead set up with the isapnp tools. Quite possibly the
install would have gone through steps to do this. So you have the first
issue of hardware initialization to the bus, which is what the pnp setup
stuff does (if PCI this is usually through bios; if ISA, it is through
an external tool). Once hardware is initialized, you still have the
normal setup of the particular device, in this case modem setup (of
which parts are common to most modems, and others are specific to the
particular hardware). Most ISA modems are not windmodems, so probably
you are correct on it not being a winmodem. But winmodems can in fact be
detected and hardware values set up for irq and address and port, but
then they sit there brain-dead when you try to use it. You might look up
use of minicom to experiment with commands to the modem. For hardware
setup, you might want to review /proc/interrupts, /etc/isapnp.conf,
setserial -a to view the /dev/ttyS? port. Device or resource busy will
indicate irq or address or port is not set up correctly, which is part
of pnp or the port; failure later indicates a software setup problem not
related to hardware initializing.
