Summary: No sound from Soundblaster Live USB since updating
kernel drivers to 1.0.10.rc3
Description:
Every kernel since 2.6.14 (I have tried rc1, mm1, mm2, and rc2) has left
my external USB sound card broken. It appears to be something in the
alsa-git-2005-11-07.patch that was posted to LKML on 11/07/05:

subject: [ALSA UPDATE] 1.0.10rc3
message-id:
<Pine.LNX.4.61.0511071457480.8818@tm8103.perex-int.cz>

Applying this alsa update to 2.6.14 also renders the card silent. The
card
is visible in /proc/asound/cards, alsamixer sees it and I can adjust the
volume, but I get no sound from xmms, mplayer, etc. I tried enabling alsa
debug and verbose printk but I was unable to find any additional messages
from dmesg or in any log files. The card is a Creative Labs SoundBlaster
Live 24-bit external. I'm using the SPDIF output to run sound through a
home theater system. I'm running debian unstable on a Toshiba laptop.

Yeah there are a LOT of bugs in the tracker and we don't have the manpower
to handle them all promptly sometimes.

FYI you should have given this BLOCK severity rather than MAJOR as you
have no sound at all and it's a definite regression.

Understood. I will do what I can on my end. Not much of a kernel hacker
but I can feel my way around. Who knows maybe I will get lucky :)

I will keep that in mind next time, thanks. btw, I wonder if the problem
might be SPDIF related. I have not dragged home a pair of speakers and
hooked them directly to the card, but I will. Perhaps that would help
identify the source of the issue.
