It happens on all version tested Dharma B1,B2,B3,RC1

My setting in audio playback are HDMI, 7.1 and DTS and Dolby passthrough. When I playback a video with a mono audio track the playback is really really really slow, around 1fps and no sound, the receiver (SONY STR-DH800) is cleary receiving no sound.
But if I change the audio playback setting to 2.0 channels the playback is correct. I think is a bug... I have to change between setting when I want to reproduce some mono content...

To clarify, it only happens when the audio has to be converted to PCM and passed to the receiver. With mono Dolby tracks the passtrought works properly.
Mono -> PCM 7.1 Ugly playback (almost freeze and no sound)
Mono -> PCM 2.0 works fine

For me mono content should be no upmixed more than 2.0 but it's akwards to change audio settings between 2.0 and 7.1 because of the content.
