hey molesza, once you set this up be sure to check playback of audio if you use xbmc's music library function. i have onboard intel hd audio with my geforce 8200 chipset and the hdmi codec only supports 48k and 96k samplerates wheras the analogue codec supports all samplerates. what was happening was that the system would try to open hdmi at 44.1k for an mp3/ogg/whatever, it would fail and default to 48k. music at 48k sounds like chipmunk music to me.... you might not notice in the music except for a slightly faster beat, but you'll definitely notice a difference in the vocals. anyway, earlier on i posted a change where you tell alsa to slave the hdmi device off the analog device and tell xbmc to play the audio to the default (analogue) device. it worked marvellously to solve my problem. i don't know for sure whether alsa is doing the resampling or its happening in the internals, i just know it works. if you need those details reposted, let me know.
