Dolby TrueHD 2.0 playback never starts
Describe the bug
- Set audio output to "direct". No other audio setting appears to matter.
- Play any video with Dolby TrueHD 2.0
My device does not support Dolby TrueHD playback nor passthrough. So this should have triggered a transcode, but doesn't. Playback doesn't start, but the UI is still available and responsive. If I select a low max bit rate in the playback UI it will trigger a full transcode to AAC and play. If I change the audio output to "downmix to stereo" it will trigger an audio transcode to AAC and play.
If I playback 5.1 or 7.1 TrueHD content, it will immediately transcode the audio to AAC and play.
It appears that just 2.0 TrueHD doesn't trigger a transcode when audio output is set to "direct".

Seems something similar is happening for me. I also have a Sony Bravia TV, though a different model. Here are the logs from the server: true-hd-2p0-stream-locking.log ...and here is the AndroidTV logcat output: Sony-BRAVIA-4K-VH22-Android-10_2024-09-04_215048.json ...and lastly the media info:

Interesting you are having issues with TrueHD 5.1. I can play TrueHD 5.1 and 6.1 just fine on my end, it's just 2.0 that seems to be the problem for some reason.
I've converted these to Opus 2.0 128kbps for the time being but I'd much rather keep the original streams if possible.
Oh no, what I did while generating those logs was start with the default audio, then cycle through the different embedded audio tracks. I was able to successfully switch to everything except the TrueHD 2.0/Stereo Japanese track, which would cause the player to hang.
