I have VU+ Solo SE, and the latest OpenPLI image (this problem was in previous builds too, so it is not related to the newest image only)
I have turned off AC3 downmixing in A/V settings. My AV receiver is doing decoding.
Some TV channels are broadcasting with AC3 and some with MPEG audio, everything is playing OK.
But there is issue with playing movie (mp4 with AAC sound) in Movie player.
When I start Movie player while I am watching channel with MPEG audio, then that movie is played OK.
But when I start Movie player while I am watching channel with AC3 audio, then that movie is played without audio.
When I turn AC3 downmixing on (in A/V settings) than playing movies in Movie player is without problem.
