Can confirm this behaviour. Additionally when using the Web player there is no sound for mp2 streams. When switching to ac3 (which gets transcoded to aac) sound is there. Can you force mp2 to get transcoded?

I investigated this issue further. This problem is not limited to the android app but applies also to jellyfin-web (since the android app is a wrapper around jellyfin-web this makes absolute sense). Jellyfin-web does some assumptions about the support of mp2 based on the browser engine and if mp3 is supported. (see https://github.com/jellyfin/jellyfin-web/blob/f426747b6210adeb71f7714a6459a41079867b93/src/scripts/browserDeviceProfile.js#L385 ff). While this is valid for the desktop it does not apply to Android based browsers. Verified by forcing let supportsMp2VideoAudio = false; then the audio gets transcoded to aac and I have audio on my mobile. Suggestions:

1. Fix the jellyfin-web code to correctly set supportsMp2VideoAudio for Android based devices (does not fix the Exoplayer problem)
2. Get https://github.com/jellyfin/jellyfin-android/blob/44d403f461f18d6f08cd360982a3879c5a1aa3b4/app/src/main/java/org/jellyfin/mobile/player/deviceprofile/DeviceProfileBuilder.kt to set the deviceProfile correctly.

Update: Option 1: This works when using the Web Player. Changed jellyfin-web on my server. Doesn't need change in Jellyfin-Android. Option 2: Have a changed version which already requests a transcoded stream (without mp2) but I can not test it because I always receive a player_error_network_failure when starting the Exoplayer for transcoded stream (DirectPlay works). This seems not to be related to this problem but I can not test any fix.
