I've complied and installed Alsa 1.0.13 without any errors. the drivers appear to be loaded correctl. Alsamixer works and controls the card. I have capture setup on the line in, and I can control the level of feedback with the "capture feedback" and the analog volume sliders. muting the digital mutes the sound when digital is on which is what I'd expect.
However I can get no application to talk to the card. playing mp3s and wavs using mplayer, mpg123, or aplay just result in the player appearing to sit at the start of the file as if it's paused. Mythtv just gives audio buffer errors.
speaker-test ran with the options -c2 -twav -Dplug:front sits for a while on front-left, then returns a write error - 5 input/output error
various information is included below.
thanks Gary
