@anyoneyun Until the tvOS app is updated past 1.0.1 so that the device profile changes take effect, this will remain the case. @UnidentifiedX I assume you are trying to use the Native player. I have identified that the native player only supports 2 channel Opus. You can see more discussion here: https://github.com/jellyfin/Swiftfin/issues/1170

@holow29 Thanks for the reply! Looked through the thread and I've decided to transcode my files to 5.1 AC3. Works fine now, thanks!

Also on a side note, even running stereo opus doesn't produce any audio. Tried with the LegacyStereo audio track as well - doesn't seem to work either. Not sure what is going on here.

Edit: Actually, I realised that OPUS audio doesn't work AT ALL when using the Swiftfin player - for both stereo and 5.1. I haven't been using the native player at all, since like the other guy, AV1 + OPUS 5.1 doesn't even load

Actually, upon further investigation, I realised that if you add a .sup file to your subtitles the audio track from the video will be gone if you use the Swiftfin player. Extremely weird, gonna open an issue when I have time. This was probably why my OPUS file couldn't play audio and has nothing to do with the codec.

Edit again: finally boiled it down to the fact that you cannot have a secondary audio source, or it will not play audio. Still not sure if it's a codec issue or just the fact that there is two audio sources, but an issue nonetheless.
