What makes this card magic is that pcm functions are performed by firmware that is loaded into the dsp core. Four play and one record channels are enabled and the mixer works, though I can't figure out the magic for the volume buttons found on many laptops with these chips. Thanks once again to Darrell and Cameron for everything they did to make this happen. We are working on resolving this. I'm hoping to get this checked in to -current soon.
Recording seems to work.
I'm not having much luck with the built-in mike on my system, but recording from the CD channel works. So I have enabled one recording channel. Please let me know if they work for you. Bugs Initializing the mixer funks up the level settings of the various channels. When allocating the DMA buffer, no check is made that the buffer was actually allocated.
