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.

Try adding printks to prepare_startup_playback_urb() and
snd_usb_pcm_playback_trigger() in sound/usb/usbaudio.c, do they both get
called when you play something?
