Jellyfin ignores maximum audio limit

[Bluegoldflag]

Hello everyone! I have a laptop which is getting a little bit old but still can play most of the movies from my server! The only problem is this device doesn't support multiple audio channels I mean 5.1 or more. I set the maximum allowed audio channels to stereo but the server still doesn't care and sends out the 5.1 audio of the movie! I tried setting it to force transcode but the audio still remained the same! If I try to play over firefox the audio gets transcoded but the image is laggy! The laptop is running jellyfin media player from flatpak running on endevouros! The server is running jellyfin(10.8.13) inside docker on ubuntu server 22.04. Hardware acceleration is enabled. Jellyfin is running over nginx reverse proxy! Thank you for your help!

This is a known issue that is fixed in 10.9, which is right around the corner.

Thank you for the information!Do I just need to recompose my container to update?

If you want to use 10.9 NOW you would need to change the tag from "latest" to "unstable".

WARNING, there are still bugs.

WARNING WARNING, upgrading to 10.9 is one way. You can't downgrade unless you made a backup of your /config folder.

What you could do is run unstable alongside stable.

Stop your Jellyfin container, make a copy of your Jellyfin docker directory, change the image tag to unstable, start the unstable image, change the network port from 8096 to 8097, restart unstable, start stable. Now you have both. This is assuming your /config and /cache volumes are relative paths.

Oh. If you want to wait until 10.9 is officially released, when it is released "latest" will correspond to 10.9.
