Thanks for quick response, unfortunately I should mention that I'm using Optical output, due to lack of 4k support of my 4 year old AV Denon Receiver (only HDMI 1.4b). So HDMI goes directly to TV (2.0 -> 2.0), and optical output to receiver but S/PDIF output setting in audio options has only RAW or PCM 2 channel to select not auto
Is there some other setting so that AAC will work through optical output?

Thanks again

Will add a option "force downmix audio(for optical)" in next version

Will that help? I mean would that setting allow passing AAC 5.1 (or 7.1) audio through optical S/PDIF to receiver as is and not stereo? Because option name "force downmix audio(for optical)" would suggest downmixing multi-channel audio to stereo and this is what we get now for 5.1 AAC tracks.

OK,my mistake.Will check about optical pcm 5.1 output for aac 5.1,If it is feasible
