Dear Team VLC,plz add transcoding all audio[mp3,wav,ape,truehd,dolby atmos,dts-hd master,aac,flac] to dolby audio[ac3]option in audio passthrough mode,so that atmos,truehd and dts-hd master audio can decode via receiver with dolby decoder.given transcoding to dolby through windows 11,therefore the volume even in audio passthrough mode can control too in VLC MEDIA PLAYER,like Kodi player's.

It's not pass-through if it's transcoded. You can't have it both ways.

Dear TEAM VLC,you are right,first trancode,and then dolby audio pass through to receiver with dolby decoder

Your request is self-contradictory.

No it's not contradictory but I believe it would require a Dolby license.

This guy has a receiver that supports AC3 but boo newer formats

Instead of using 5.1 analogue connections that would be the right way to go he expects you to decode the audio track and re encode on the fly to AC3.

An awful idea for the poor CPU. Lag and also loss of quality.

It is obviously contradictory. Pass-through mode, by definition, doesn't involve encoding.

What you're describing is not pass-through mode, and doesn't need anything from VLC. Just put a virtual surround sound card that encodes to AC-3 in the backend. As you noted, quality will probably be bad and the CPU will suffer a bit.
