No response
Reproducible in the demo app?
Not tested
Reproduction steps
- Download a demo video file with a frame rate that is not 60 fps and an audio track that is either DD, DDP or Dolby TrueHD
- Set the Nvidia Shield to always passthrough audio (don't use the Dolby Audio Processing option)
- Open Just Player
- Long press the settings icon and enable the frame rate matching option
- Play the video
- Open jellyfin-androidtv
- Enable the frame rate matching there as well
- Play the video
- Disable the frame rate matching option in both players and repeat the test
Expected result
The Soundbar/AVR system should report receiving a DD, DDP or a TrueHD audio, regardless of matching or not the framerate.
Actual result
With the frame rate matching option, multi channel PCM will nearly always be reported instead of the expected Dolby passthrough.
From my testings with the frame matching, about 10% of the time the Dolby passthrough actually works. I don't know if this is a timing issue with the activation of the frame rate matching or if it is something else.
When disabling the frame matching, the audio passthrough always works.
