@popcornmix did the sample file help you reproduce the issue?

Thanks for file.

With command line omxplayer, it behaved quite well, very slight stutter when switching from 2 to 6 channels. Both passthough and non-passthrough.
With xbmc it stalled for a second and I got some video artifacts.

It didn't hang for me.

Do you get a different effect? What xbmc build are you using? I'm using something similar to rbej's Gotham build.

The crash only happens in xbmc with dts / ac3 passthrough enabled so you will need a dolby/dts capable device to reproduce this. When audio is downmixed to stereo playing continues with light artefacts. This happens in xbmc 12.1 release and later nightlies. Standalone omxplayer does not crash, it handles the audio change properly, both on audio downmix and audio passthrough.
