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.

I just tried ALSA 1.0.11rc1 with a 2.6.15-rc6 kernel and the problem
persists :/

If anyone is interested I built the latest ALSA CVS against
2.6.15-rc7-ck1:

jason@jackass ~$ uname -a
Linux jackass 2.6.15-rc7-ck1 #20 SMP PREEMPT Wed Dec 28 12:05:42 CST 2005
i686 GNU/Linux

jason@jackass ~$ cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.11rc1.
Compiled on Dec 28 2005 for kernel 2.6.15-rc7-ck1 (SMP).

The USB sound card still does not work :(
Exact same results as the initial bug report.

I guess if I want to stay with current kernels I will have to revert alsa
to < 1.0.10 if I want USB sound to work :(
