Android application cannot playback audiostream (DTS-HD MA Stereo in *.mkv)

[voodoo5_6k 29]

I wanted to start watching a movie but then wondered why it wouldn't start. The TV switched to DV mode, but the picture stayed black. Using the remote, it looked like playback was paused, but it wouldn't resume on unpausing. Switching the audiostream however worked.

I went to a computer and logged into the emby server and started playback from there (browser). The audiostream worked fine.

Back to the TV, and switching around between the audiostreams. On rare occasions the not working audiostream would start playing, but I cannot reproduce this. All others worked for the Android application (at least one of them is using the same codec).

Emby server is latest stable, Android application is latest beta (public IP removed- why is that in there?), logs attached.

Thanks

Thanks Luke.

But I'm not sure why it would need to transcode. This is a DTS-HD MA track. The other DTS-HD MA track is working fine.

In the log, it says:

Fri May 29 21:00:32.621 GMT+02:00 2026 DecoderAudioRenderer: Audio sink error
  androidx.media3.exoplayer.audio.AudioSink$InitializationException: AudioTrack init failed 0 Config(48000, 252, 8, 4500000) Format(4, Surround 5.1, video/x-matroska, audio/vnd.dts.hd, null, -1, en, [-1, -1, -1.0, null], [6, 48000])

This is a stereo track however, not Surround 5.1. Is it trying to initialize the audio sink for 5.1?

Looking at the track in e.g. Audacity also shows it as stereo.
