[Alsa-user] No sound when logged in, despite sound at login screen
I (just today) installed a new kernel for Linux to rememdy a few sound
problems requiring
higher resolution timers than the default Ubuntu 6.10 kernel offerred.
Everything, to
the best of my knowledge, went smoothly, and I installed the 1.0.14rc4
version of the
necessary ALSA modules, considering that I compiled nothing more than
the basic sound
options (no ALSA, no OSS) into the kernel. (The modules were the
driver, libs,
utilities, and oss.)
The reason I installed the most recent ones instead of, say, 1.0.13 or
lower was that all
of the previous ones that I tried failed on the make procedure, at
roughly the same
spots. 1.0.14rc4, however, configured and installed fine. I loaded the
snd_emu10k1,
snd_intel8x0, snd_pcm_oss, snd_mixer_oss, and snd_seq_oss, after which
both my internal
Intel soundcard and PCMCIA Soundblaster Audigy 2 ZS were recognized by
the system. (I've
also included those modules in /etc/modules, and they load on each startup.)
My issue is that I get sound in the login screen, and the speakers make
their usual pop
during both startup and shutdown at the Ubuntu splash, but as soon as I
log in, in either
kernel (2.6.21.1, patched with the real-time preemption patch, and
2.6.17.11-generic,
which I was using with sound just fine before), sound disappears. I can
use alsamixer
fine and adjust the sound, as well as the gui utilities provided by
Ubuntu, but no sound
is produced in any application or situation (it disappears even before
one reaches the
jingle for logging in). All I know is that in the terminal, whenever I
perform most
operations (regardless of if it's audio or just a gedit here>) I get the
following messages :
ALSA lib confmisc.c:1286:(snd_func_refer) Unable to find definition
'defaults.pcm.dmix.device'
ALSA lib conf.c:3510:(_snd_config_evaluate) function snd_func_refer
returned error: No
such file or directory
ALSA lib conf.c:3982:(snd_config_expand) Evaluate error: No such file or
directory
ALSA lib pcm.c:2144:(snd_pcm_open_noupdate) Unknown PCM default
Those don't change regardless of the operation, and I haven't
encountered any different
ones either. As for further information, well, all I know is what's
given by running
aadebug, as was suggested in the alsa troubleshooting section of the
wiki. I've attached
the file with the output from the utility for convenience ; just a
simple text file.
Preferably, I'd like to get sound working soon-ish, and I appreciate any
help that can be
given. I'll also probably post a similar message to the Ubuntu forums
to see if anybody
from there can help.

`alsactl` holds its state in /var/lib/alsa/asound.state, which I had
explicitly deleted, and then did a quick shutdown (sysrq+u&s&b), so the
shutdown scripts would not recreate it. All volume levels were back to
their defaults, just as expected. But skype still worked basically with
the same configuration that I had when it was _not_ working.
It is almost like there is an additional place that holds the state that
I am not aware of.

When trying to get a Chaintech AV710 working I noticed that alsa seems
to be stateful in just the way you did. My changes would seem to have
no effect. I think the way I worked around it was to get things set up
the way I wanted and then do /sbin/alsactl store and /sbin/alsactl
restore . There are probably internal values stored and restored
by default. Just an opinion as I am no expert on this.

The reason I started digging for it was that skype was extremely choppy.
I would be able to complete the test call as only one side would speak
at a time, but a real conversation was a nightmare. First I suspected a
duplex issue, but after your answer I tried arecord/aplay combo and it
worked. So I looked deeper and found some references to asym. I decided
to give it a try and created the following .asoundrc:
pcm.card0 {
type hw
card 0
}
pcm.dmixer {
type hw
card 0
}
pcm.skype {
type asym
playback.pcm "dmixer"
capture.pcm "card0"
}
pcm.!default {
type plug
slave.pcm "skype"
}
Skype started working. However I needed !default to be a different card,
so I just started testing different configurations of stuff and all of a
sudden realized that skype _still_ works, no matter what I do. I removed
the .asoundrc, emptied /var/lib/alsa, reordered modules so the skype
card becomes card1, shut down the machine completely - skype still
worked after everything I did. On one hand I got what I wanted, on
another I am really irritated since I have no idea what happened, and
how did the change become permanent. Could someone point me in the right
direction? Thanks!

I'm mainly interested in the high quality analog stereo playback. Everything else is gravy. Based on the website in my other response, I might look at the driver to see if there is a quick hack to get anything else working. Just from dipping my toes in I can see that this requires some domain knowledge to code; the acronyms and abbreviations are plentiful. I'll have to take that as it goes.

[Alsa-user] No sounds with SIS AC97 on Notebook ASUS 6000KM
Hello, i am using a Notebook ASUS 6000KM with Gentoo (Linux version 2.6.20-gentoo-r7)(gcc-Version 3.4.6 (Gentoo 3.4.6-r2, ssp-3.4.6-1.0, pie-8.7.10)). All in all it works fine, but without sounds! 'alsamixer' brings the following: >> localhost henrynick # alsamixer >> No mixer elems found alsaconf starts without errors, but brings only one information, that there is 'no supported PnP or PCI card found'. alsa-moduls are in the kernel and the driver for SIS AC 97 also, but it doesent makes a noise.

Re: [Alsa-user] Revolution5.1: can't mute sound
Hello, Sorry for a delayed reply, I was far away from my computer these days. I've tried to test microphone recording, but it seems that I'm using too old ALSA: my alsamixer does not have "Capture Channel" selector. I'll try to upgrade ALSA and test it again. My overall impression from the card is quite positive: sound quality is really great. Playback works out of the box on any distro with alsa>=1.0.13, but there are some problems, some of them seems to be solved in later versions which I'm going to try. > When I was reading them yesterday, the developers said that they have > difficulty with that card because M-Audio is not providing specs. At least the situation is better than with Creative products: their x-fi series is still not supported by alsa at all and they do not want to provide any information about it to help. stan wrote: > On Sat, 05 May 2007 15:44:17 +0400 > Vladimir <[EMAIL PROTECTED]> wrote: > >> Hello, >> >> I'm have a problem with Revolution5.1 card: I can't mute the sound. >> I've tried alsamixer and kmix: both do nothing when I'm trying to >> mute PCM. >> >> Is it known problem ?
