Some multichannel FLACs playback as stereo

[gunjan]

Hello!

First post here. I've been using Jellyfin for over a year now, and I absolutely love the application and the community around it.

Coming to the issue I am facing, I have two albums in multichannel FLAC. Album A is 5.1 channel 24 bit and 96 kHz. Album B is 5 channel 24 bit and 48 kHz. Both have been ripped from DVD sources (albeit different encoders). Album A plays back in 5.1 channel whereas Album B only plays back in stereo. When I look at the Jellyfin dashboard, for both albums it says that the device is compatible with the file and it is being received without modifications. When I look at the AV processor, for album A it says PCM audio 96 kHz 5.1 channel, whereas for album B it says Dolby Digital (DD+) audio 48 kHz 2 channels.

My setup:

• Jellyfin client - Amazon FireTV stick 4k Max (gen 1) - version Jellyfin Android 2.6.1
  
• Fire stick feeds an AV processor that I think should support playback (since album A works) - https://iotavx.com/IOTAVX-AVX17_1
  
• Jellyfin server 10.9.7 running on Debian inside an LXC on Proxmox (everything updated).
  

I tried to find the relevant log but there was nothing.

I found one issue on GitHub that might be related - https://github.com/jellyfin/jellyfin-and...ssues/1755

Is there an issue in my setup or the audio files? Can I convert album B to a different format so that it plays back in multichannel?

Thanks in advance for any help!
