HDMI connections throughout. No other audio output devices.
Issue: When playing videos with AAC audio, there is no sound output detectable. Other audio formats (AC3, Dolby, DTS, etc) play just fine as passthrough audio. Other players such as Kodi, JRiverMC or MPC-HC output AAC audio just fine.
So, is there a setting either in the PMS or P-HTPC that I am missing in order to get decoded AAC audio to my AVR?
Alright. I have a Plex HTPC log.
Opened the app, played a video with AAC audio. Stopped the player. Exited Plex HTPC.
What info am I looking for that could help with this issue?
Also, tried playing a video with MP2 audio. Same result, no audio.
I see in your logs some instances where audio-only files are being played. Were you navigating to TV shows with theme music set to play? (Settings → Experience → Theme Music). If so, did you hear it?
What happens if the TranscodeToAC3 is set to false in the plex.ini file? If it is set to true, and there is a list of passthrough codecs, will Plex transcode the non-passthrough audio to AC3?
I find this line in my plex.ini file, and I want to set TranscodeToAC3 to true:
{"name":"wasapi/{dc9873dc-d9e9-4aac-934b-48a2f424b396}","description":"DENON-AVR (NVIDIA High Definition Audio)","present":true,"lastPresent":"2022-07-01T20:45:08.952Z","kind":2,"transcodeToAC3":false,"passthroughCodecs":["ac3","eac3","truehd","dts","dts-hd"],"channelLayout":"7.1"}
Also, there is this line:
