XBMC Live – Sound over hdmi

When I installed XBMC 9.11 on my Acer Revo AR-1600 I had a problem with getting the audio working over the HMDI. It appears that the fix is to a a new file .asoundrc in the xbmc users home directory. SSH into the machine and type the following:

touch ~/.asoundrc
nano ~/.asoundrc

When the nano editor open up the .asoundrc file enter the following into the file:

pcm.!default {
type plug
slave {
pcm "hdmi"

Press ctrl+x to exit, followed by y to save the changes. Then the only thing remaining is to fix the settings in xbmc itself. Load xbmc and go into the audio settings and set the following.

Audio output (digital) => Digital
Audio output device => hdmi
Passthrough output device => hdmi
Downmix multichannel audio to stereo => ON

My revo is currently hooked directly to a tv, so there were no options about a receiver selected. I haven’t been able to see if the DTS or Dolby Digital options work.
