It's hard to tell without more information. What linux are you running?
Fedora, MythDora, etc. What sound hardware are you using? Onboard (nForce,
VIA, etc) Or Audigy, Turtle beach?

I also use the .asoundrc w/ mixed digital selected. One interesting thing is
I'm using the same .asoundrc in F8 that I used on FC6, however, under FC6 I
got both mixed digital and analog output from analog sources. Under F8, all
output is digital only. I have pulseaudio disabled...
