No Dolby Digital Audio Passthrough - akrausz - 2024-06-14
Hello all. Very impressed with Jellyfin so far.
Running 10.9.6 on Asustor NAS, installed with Docker. Using Fire TV Stick 4K Max client, Jellyfin changes the Dolby Digital audio and sends PCM to my receiver. Jellyfin does not change DTS, sends it to the receiver untouched. Other apps (Kodi, Netflix, etc.) send Dolby Digital untouched.
Can Jellyfin pass through Dolby Digital untouched to the receiver? If so, will include a log.

In the Android TV client there is a setting regarding pass-through. On the Jellyfin home screen click on the gear in the top right, then playback. About 2/3s of the way down are the dolby/dts pass-through settings. What are they currently set to.
Also, what kind of ARC does your TV support?

Fire TV stick client audio settings-
Audio output: Direct
Bitstream Dolby Digital audio: checked
Bitstream DTS audio: checked
The stick is plugged into the receiver. These specs say TV has ARC, not sure version.

Looks like this might be a behavior caused by Android/FireOS?

Thanks. I read through that and it was nice to get a definition of what the settings "Best Available" vs "Dolby Digital +" do on the Fire TV stick. So when I change the Fire TV stick to "Dolby Digital +", then it correctly passes DD+ to the receiver. Unfortunately, it sends everything to the receiver as DD+, even my stereo music.
So, the Fire TV stick setting "Best Available":
- converts DD/DD+ to PCM
- does not convert DTS
- does not convert PCM
Fire TV stick setting "Dolby Digital +":
- converts PCM to DD+
- does not convert DD/DD+
- does not convert DTS
With Kodi and the Fire TV stick setting "Best Available", none of the above are converted...which is what I am after.
