I'm having some issues with sound in different movies...
The setup is a Ubuntu 10.04 Desktop + XBMC, latest as far as I know.

I previously ran 9.10 and all movies worked without any
issues, but know I can either get sound in mkv/AC3-movies
_or_ AVI/MPEG, depending on what setting I use in Ubuntu.

To clarify:
- If I use the setting "Analog Stereo" in the Ubuntu sound
settings, MKV-files with AC3 works and the receiver recognize
the digital sound but when I try to play AVI/MPEGs (or even MP3s)
XBMC says it fails to initialize the audio.

- If I use the setting "Digital Stereo" in Ubuntu, the complete
reverse media works in XBMC. AVI/MPEG/MP3s work but not MKV/AC3.

Hardware:
- ION plattform
- Optical SPDIF to receiver for sound
- HDMI to TV for picture

But, as I said earlier, this worked flawlessly before 10.04.

I've tried some different .asoundrc settings but none has
got me any closer yet.

aplay -l:

Does anyone have a solution to this or can point me in the right
direction on what to search for?

This is just so typical... While writing the first post I cleaned up some .asoundrc snippets and read some more threads on the topic.

Decided to try the following .asoundrc

Code:
pcm.dmixer {

  type dmix

  ipc_key 1024

  slave {

    pcm "hw:0,1"

    period_time 0

    period_size 1024

    buffer_size 8192

    rate 48000

  }

  bindings {

    0 0

    1 1

  }

}

and sure enough, after a reboot and using default for analog audio and iec956 for pass through in XBMC I got it working.

This is the thread that finally solved it:

Hope this will help someone.
