Can you confirm that other files, mp4, mp3 play Ok. If so, looks like you'll need to upgrade.

I didn't test for 5.1 only audio, I've also deleted the file.

I'd suggest getting a 5.1 test file (Google it - they do exist) and try that.

I also guess you have run Yamaha's speaker test function?

There is these two whole series and I've tried several episodes in both and they aren't working. I however have multiple other files that all work fine. Even some that have AAC audio so perhaps blaming AAC is premature. I don't know what else these two series have in common.

so currently you get stereo only. for such media files I put it through ffmpeg - adding additional AC3 track to the file. all original streams are just demuxed and muxed back with additional audio track. takes 2-3 minutes and video quality is untouched.

I might try to add a AC3 track though I think these files are stereo only so it might not be the problem. Shouldn't hurt though.
