Hi all!
I finally decided it was time to upgrade to the 2.6 kernel. So I have
compiled myself a kernel, based on Linus' 2.6.7 with the Ruby patches.
I need those for my local multiuser setup. It all seems to work very
nicely, except that I lost my sound.
The problem is, I'm not really getting any error messages I'm able to
see. Everything seems quite nice, it is just that I'm not hearing
anything...
Has anybody got ALSA working with the alsa-base and alsa-utils currently
in Sarge? There are some examples lacking (bug reports have been filed
on those, I'm sure they are working on it), so I'm feeling I'm just
blindly trying different things but having no clue what they are
supposed to do.
I guess a good start is to cite the output of my lsmod:

We see snd_cmipci, and cmipci is good, that's the driver for my sound
card. First I tried compiling most stuff into the kernel, but the one
I'm running now, the whole sound system are in modules. How does this
look?
I've been experimenting with files here and there to get it to
understand that I'm using ALSA 1.0, for example:
root@owl:/etc/alsa> find .
.
./modutils
./modutils/0.9
./modutils/0.9/modules-0.9.conf
./modutils/0.9/file4k6mBy
./modutils/0.9/fileygRrGd
./modutils/0.9/1.0
./modutils/0.5
./modutils/1.0
./modutils/1.0/1.0
./0.9
And symlinks here and there....:
root@owl:/etc/modprobe.d> ls -l
[snip]
lrwxr-xr-x 1 root root 22 Jun 30 15:12 alsa
-> /etc/alsa/modutils/1.0
-rw-r--r-- 1 root root 86 May 2 12:50 alsa-base
...and
root@owl:/etc/modutils> ls -l
[snip]
lrwxr-xr-x 1 root root 22 Jun 30 15:09 alsa
-> /etc/alsa/modutils/1.0
-rw-r--r-- 1 root root 26 May 2 12:50 alsa-base
-rw-r--r-- 1 root root 121 Apr 6 2002 alsa-path
Then, I've ran alsaconf, and it just comes out telling me everything is
OK. Also, I tried to insert some magic in one of these 1.0 files and
run dpkg-reconfigure. It too told me everything was OK. update-modules
and restarting ALSA I've done it all... But not in a very structured
manner, since I don't have much idea what all these things are supposed
to do... :-)
Then, there's the mixer. I've yanked everything I could up to max.
Interestingly, as I push the volume of the "PC speakers" up to 100, I
(increasingly) hear a lot of noise on the speakers. Furthermore, it is
clearly generated by the PC, as the noise follows the noises from the
box, e.g. hard drive noises... So, it seems there is something coming
out from the sound card, but it isn't the music I was expecting to
hear... :-)
For some time, I thought it was mostly that I didn't get modules loaded
or something. I supposed that that's what the missing examples are
about. But from the lsmod, to me it looks like they are...
I've got quite a lot of trouble with arts lately. I'm using KDE, and
usually play music with noatun, and arts seems to have some problems at
startup, killing itself and stuff. However, I've been testing with
playing "known good files" with alsaplayer, so this shouldn't have any
impact, I thought.
I've tried ALSA before, with varying degrees of success, I've got it
working for some periods, and some periods not, and I can't really
point out why. Recently, I've been sticking to OSS. Except for just
checking that I could compile and boot 2.6 in the late -testing period,
it is the first time I've tried 2.6.
Finally, I saw some RC bugs have recently been closed. Anybody know if
those would have had any effect, and if we'll see new uploads soon?
Any hints, please?
Best,
Kjetil
