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 <insert file
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.
