Hi Jim,

Just to prove you are not alone, I also get the exactly the same issue:

lspci:
00:0f.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 07)

log:

Advanced Linux Sound Architecture Driver Version 1.0.14 (Fri Jul 20 09:12:58 
2007 UTC).
PCI: Found IRQ 5 for device 0000:00:0f.0
ALSA device list: #0: SBLive 5.1 [SB0060] (rev.7, serial:0x80611102) at 
0xe000, irq 5

I use a restore file at boot, so run /sbin/alsactl restore

And updating this morning to 2.6.23.8 produces:

/usr/sbin/alsactl: set_control:991: warning: name mismatch (IEC958 Playback 
Mask/IEC958 Playback Default) for control #228
