Summary:                    No sound since ~2.6.3
Description: 
 Greetings,

Running Debian woody/sarge/etch, the last time sound worked on my Fujitsu
Lifebook P2120 was with 2.6.3 (or maybe 2.6.5, but not with 2.6.8 or
anything since).  Esd doesn't work, nor do system beeps, and GNOME volume
control says no volume control elements are found.  I can get ALSA working
with 2.6.8 on all of my other machines, and with 2.6.15 on all that I have
tried.  alsamixer runs and shows levels which I can change, but still no
sound.

An identical ALSA setup worked with sarge under 2.6.3 but not 2.6.8. Tried
running alsaconf again to no avail.  Under 2.6.3, at least when doing
hardware mute and then un-mute (Fn-F3), un-mute beeps; on newer kernels,
there's no beep.

Now under Debian etch (testing), even 2.6.3 no longer works properly:
sounds played through esd simply repeat the first second or so over and
over again. I keep upgrading the kernel (most recently to 2.6.16-rc5 in
experimental) hoping that this time it will finally work, but it hasn't in
that long...

Debian etch has alsa 1.0.10-3, and lsmod shows the following sound modules
installed:
snd_ali5451 20172 1
snd_ac97_codec 82784 1 snd_ali5451
snd_ac97_bus 2048 1 snd_ac97_codec
soundcore 8672 1 snd
snd_page_alloc 9800 1 snd_pcm

lspci shows:
0000:00:04.0 Multimedia audio controller: ALi Corporation M5451 PCI
AC-Link Controller Audio Device (rev 01)

What other information would help to diagnose/fix this problem?

Thanks,
Adam

"Hmm... Three months with no help on this bug."

Um, maybe you could try searching between 2.6.3 and 2.6.8 to identify the
change that broke it?

Check whether it's a driver but or another system regression.
If you see the entry in /proc/asound/cards after loading snd-ali5451
module, the driver is mostly OK.  If not, you should have kernel error
messages.  Compile with debug option, --with-debug=full for alsa-driver
configure script.
