Well there are some differences I see:


-       flags: HARDWARE HW_MUTE_CTRL DECIBEL_VOLUME LATENCY FLAT_VOLUME 
DYNAMIC_LATENCY
+       flags: HARDWARE HW_MUTE_CTRL HW_VOLUME_CTRL DECIBEL_VOLUME 
LATENCY DYNAMIC_LATENCY

There are two differences here. The live system seems to have 
FLAT_VOLUME but the intall has it disabled. Also the live system does 
not support HW_VOLUME_CTRL but the install does...

(although the bit above is just for output, not input).

This is another difference. The alsa.components are different. Not 
really sure what they mean to be honest tho' :s


I suspect that your probe_mode parameter seems to me to be where the 
problem is. Perhaps you can work out how the module is loaded on the 
live cd and what params it takes etc. so as to fully replicate the setup 
on the install?

I'm a bit stumped to be honest :s
