[Alsa-user] Help configuring HDSP9632
Hi guys,
I've been trying off and on for weeks now, but I can't get my RME
HDSP9632 configured under ALSA properly.
(Is it me or does ALSA really not make this an easy process? I can't
find anywhere to get any feedback from the system on configuration
errors. Hell, if you make a typo in the config file, you only find out
because of some scary-looking output from aplay. The docs on the website
seem to be quite old and often conflict with each other and I can't find
any relevant man pages.)
Anyhow, the card works out of the box, insofar as it lets one
application play sound through it at a time. So I'm trying to do the
common thing of configuring dmix to let multiple applications output
sound at once. Nothing fancy, really! At least, at this point.
My /etc/asound.conf file is as follows (pieced together from tuts and
the like):
pcm.!default {
type plug
slave.pcm hdsp9632_dmix
hint {
show on
description Default device: Plugs into hdsp9632_dmix.
}
}
ctl.hdsp9632_dmix {
type hw
card 0
}
pcm.hdsp9632_dmix {
type dmix
ipc_perm 0660
ipc_key 1025
ipc_key_add_uid false
slave {
pcm hw:0,0
rate 44100
channels 2
period_size 1024
buffer_size 4096
}
bindings {
0 0
1 1
}
hint {
show on
description hdsp9632_dmix: The dmix plugin - plugs into
hdsp9632.
}
}
Using this file, I get
# aplay -L
null
Discard all samples (playback) or generate zero samples (capture)
default
Default device: Plugs into hdsp9632_dmix.
hdsp9632_dmix
hdsp9632_dmix: The dmix plugin - plugs into hdsp9632.
which is what I hope for. But, if I try and play something with vlc, I
get an error message and No AutoSync source for requested rate comes
up in dmesg. The card is currently set to clock master at the same
sample rate as the audio (44.1kHz).
If anyone can shed any light on what I'm doing wrong (and, ideally, some
methodology on configuring ALSA which doesn't require scrabbling around
in the dark!), I will be grateful until the end of time.
Thanks a lot,
Matt

[Alsa-user] Thinkpad X41 Tablet audio (AD1981B) unusably quiet after upgrade to 2.6.37 kernel
Hi all, (I sent this last week but I guess it died in the moderation queue?) Audio worked well on my Thinkpad X41 Tablet (using Arch Linux) until I did a system upgrade a few days ago that included a new kernel. At first I thought I had no sound at all, but after some troubleshooting I realized there is sound, it's just really really quiet. If I play an MP3 with all mixer controls unmuted and volumes at max I can barely make out music with quality headphones. Built in speaker output works but is entirely drowned out by system hums and clicks. The mute and volume mixers appear to work. There don't seem to be any errors or changes in the output of the various alsa utils, though I'm not very familiar with the linux/ALSA system. The problem is independent of audio program or file source. I reran alsaconf and reset my mixers and tried again, no change. Output of alsa-info.sh here: http://pastebin.com/ep8R2mLB Is this a regression? Is there anything I can do to help get it fixed?

Re: [Alsa-user] Help configuring HDSP9632
Hi Matt,
I didn't use a RME HDSP9632 for quite a long time (also I never used it
with the dmix plugin). However, the dmesg message sounds like a clock
source problem. All I can suggest is to check for the correct rate
settings, e.g. compare what hdspconf is showing to the output of
cat /proc/asound/card0/hdsp

That in general has nothing to do with the card or the driver of the card.
Most cards do not allow multiple inputs to all play at once. It is software.
It is often pulseaudio or jack could be used as well.

The alsa users documentation has long long long been its greatest shortfall.
And noone seems to be stepping up to the plate to write the docs. One of the
problems with the open software movement. In a proprietary system, the company
would assign someone to write the docs, whether they wanted to or not. In the
free software world, people do things they want to do. Noone wants to write
alsa docs--Noone does write alsa docs.
(Despite that I like the free software movement, but it does have its
problems.)
Thanks a lot,
Matt

Re: [Alsa-user] Help configuring HDSP9632
In theory you don't need the dmix thing anymore. If your applications
use ALSA natively, it will automagically mix sound from several
applications (in software). If the applications use OSS, you can
force it to use alsa with aoss. BITD you'd run esddsp or artsdsp -m
app to do this sort of thing. Depending on the sound daemon of
choice you happened to be using. These days those daemons just get in
the way, chew up resources and cause XRUNs or other woes. If your
applications are configured to use ALSA, this should be a non-issue.
Assuming that you're running something current and not RH 5.1 from
some book or something.
In the few times that I tried to use dmix BITD, it was generally the
cause of problems, not the solution. If your applications use OSS and
you don't launch them with aoss, then they will lock the device (per
days of old). I'm not sure if that's addressed with oss emulation or
not. And aoss isn't perfect as something like a browser will launch
pop ups that are NOT launched with aoss and break the very thing you
were trying to avoid. Mostly problematic with internet gaming where
the games are pop ups. But for most other application you can select
the audio system of choice. alsa, oss, jackd, artsd, esd,
pulse-audio, and probably others. Alsa, having the least overhead
IMO, if you're coming up short on system resources.
check your .asoundrc and whatever system defaults were created for you
or by you in /etc/. I'm not sure of that locations default naming
convention as it probably varies between distros. alsa.conf?
asound.conf? +/- an /etc/ or /etc/alsa/ or /etc/sound/ or ??? And
various tricks of old to delete the asound.state file to force new
defaults. Located at /var/lib/alsa/asound.state on my system. YMMV
HTH,

[Alsa-user] K42Jc Notebook(ALC269) port switch between headset, headphone, mic
Hi, I want to switch between headphone, headset, mic input/output modes when I plug in devices. Alsamixer shows two capture channels, one is for the internal mic. I don't know how to use the other. I've tried switching some things on and off in hda-analyzer but I failed to get the functionality that I wanted. This notebook only has one audio port(TRS 3.5mm), so the selection is vital if I'm going to use an external mic. Currently the port is acting as an output only port. And something fishy goes on when I select Analog Stereo Input in profiles in Sound Preferences. It lets me use the external mic through the audio port but only if I push the jack half way, the input is detected and I can record it(but there's no sound output after I select this profile, its input only). I some how think that this is the mic mode and if I can get it to work on headset mode then I'd be able to use it for input and output. This is the information that I got from the script, http://www.alsa-project.org/db/?f=e70dae201e5d830874536be93090aef0454c8c1e Thank you, - Madura A. -- Free Software Download: Index, Search Analyze Logs and other IT data in Real-Time with Splunk.
