Comment 39 for bug 597056

another thing I found interesting but probably has nothing to do with it is, mixer 0x0e the 3rd of 4 analog mixers doesn't seem to work on anything (headphones or line out) but if I point headphones to any of the other 3 mixers I get sound to headphones (with speakers selected in output devices of course). I tested pointing headphones 0x14 to the same mixer in osx (0x14-0x0e-0x04) mapped & headphones still have sound so mixer 0x0e works in osx, just another peice of odd information I thought I'd throw in.
I should note I'm still on "model=auto" in alsa-base.conf. I get all kinds of different results when I mess around with that & not sure what is changed by changing the model but it seems like too many variables for me to figure out.
