AC3 Passthrough partially broken
#1
Hello
I have a problem in current Beta (v17 beta 1 and beta 2) concerning TV-Channels with ac3 audio streams, and would be really glad if someone could give me a hint on how to remedy this.
The audio chain should be capable of decoding every codec.

Whenever i stream a tv channel through tvheadend backend the AC3 stream gets decoded and the output format is PCM.

When i play a mkv containing ac3 everthing seems to work as expected:

This has already been working, but i made some changes in the past (Kodi v17 beta1, beta2, another graphics card), and i am unsure which one broke this.

Many thanks to anyone having a look at this

Any livestream will not get passthrough anymore. It's an intentional change.
Read/follow the forum rules.

Thanks for your reply.
Good to know that it isn't a problem with my setup, but a bit disappointing that this got changed.
Sorry for asking, but i didn't find any related topic. Do you have any thread or bug where i can read about the consideration why this behavior got applied.
