Thanks for the info.

No, I don't pass any model parameter, partly because I didn't know about 
this parm until recently, and partly because I'm not sure what the 
correct value should be.  ("head -n 1 /proc/asound/card0/codec#0" says 
"IDT 92HD71B7X", but I'm not sure where to go to look up the model 
number from that.)

Will check the change log and see what's of relevance.

Thanks,

DR
