This will get spdif + hdmi audio working with dmix thus allowing crossfading in xbmc!! :-)

Works like a charm on Asrock ION 330HT system and is probably a starting point for non-ion systems.

save to /etc/asound.conf or .asoundrc

Hope this helped.

The good thing is that my hick-ups and pop-ups are gone when switching from one song to another (using spdif). The bad thing is that I that no my hdmi crackles. I also have issues when swithing from one song to another that I have to press play one more time. Also the screen is quite smaller when I finish watching a movie using hdmi. When I look at my xbmc.log and find these errors:

This config seems to work much better! At least it doesn't give me hdmi problems.

Code:

        pcm "both"
