Package: linux-image-2.6.16-rc5-686
Version: 2.6.15+2.6.16-rc5-0experimental

Greetings,

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).  An identical
ALSA setup worked with sarge under 2.6.3 but not 2.6.8.  Tried running
alsaconf again to no avail.  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.

Esd doesn't work, nor do system beeps, and GNOME volume control says no
volume control elements are found.

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

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?

Thank you for providing this mechanism for testing and reporting on a
-rc kernel! I hope we can fix this before 2.6.16 is released.

-Adam

2.6.8 through 2.6.16 (in the bug)
alsa 1.0.11-2
Debian etch

No, that's already in etch.

/proc/asound looks pretty much normal, indicates the snd-ali5451 module.
I can send a tarball if that would help.
alsamixer shows MM for 3D Contr, Mic Boos, IEC958, Caller I, External,
and Off-hook (?).  Turning off MM...  Oh my gosh, turning it off on
External makes the sound work again!

Hooray!  Thanks so much!

Was more like very frustrated! :-(  I kept trying new kernels hoping
"this will be the one"...

Thanks much for the reply!
