HDMI Pulseaudio and ac3 passthrough - …

my guess is, that pulseaudio grabs your spdif device as second output device. but to use passthrough, the ac3 stream has to be the only one playing on that device. whats the output if you do: mplayer -ao alsa:device=spdif -ac hwac3 <some file with ac3 audio>

The HDMI is connected to the Nvidia GTX 560Ti card and I have installed the propriatary drivers (295.20) I had linux mint 11 installed before and had sound via HDMI and also ac3 passthrough worked for Dolby surround (via spdif in VLC and Mplayer). I think I uninstalled pulseaudio on my previous Mint 11 to get it to work.
