Playback stops when audio changes from stereo to 5.1

[tuutsie]

Hi,

Any ideas on this problem: playback stops on certain tv-series mkv files when audio track changes from 2.0 to 5.1 after the "prevously on..." intro. Problem disappears if I disable audio passthrough by unchecking the "Dolby Digital (AC3) capable receiver" option.

Passthrough can again be enabled if resuming playback after the point where the playback stopped.

This problem didn't happen until this latest version update.

Here is the debug log from when the playback stops:
