Re: No sound on a Thinkpad T61 w/ ALSA and AS1984 sound card (redux)
I'm going to amalgamate all of your thoughts into a single email for
simplicity - not sure if that's correct protocol or not, so let me
know if it would be better if I replied to each email individually.
Thanks everyone for all of the help!

I have no idea - honestly, I just went with the out-of-the-box debian

According to alsamixer and the xfce volume control applet, I'm
controlling the right sound card (they report HDA Intel and HDA Intel
Analog Devices AD1984, respectively).

I installed linux-image-2.6.24-etchnhalf.1-686 to check, and still no
sound. Historically, however (as in, before I started having problems
a few days ago), I've had sound work on a 2.6.24 kernel before.

I didn't have this in my alsa-base file, and I've now added it. Still
no sound, though.

Nothing that I can see, unfortunately. Master is at full, headphones
reads 00, PCM is at full, speaker reads 00. IEC958 is off, but turning
it on doesn't seem to change anything. All the mics are muted.

Gah! I must've messed up the copy/paste or something. Thanks so much
for your diligence. Here's what it should have read:
$ lsmod | grep snd_hda_intel
snd_hda_intel 331032 2
snd_pcm 62820 2 snd_pcm_oss,snd_hda_intel
snd_page_alloc 7496 2 snd_hda_intel,snd_pcm
snd_hwdep 6308 1 snd_hda_intel
snd 46724 14
And here are the other commands (lsof -n | grep /dev/dsp returns nothing):
$ lsof | grep /dev/snd
