Android TV Sound downmix or auto causes an issue.


Recommended Posts

I am on 3.5.1 server and 1.6.0 on the clients. 

It might be happening with more movies but 2 movies i have give me an odd issue.

For 101 dalmations 2 I cant play this movie unless i have the client use downmix to stereo.

For the movie Lion King the audio crackles and is pretty lousy if i leave it on downmix to stereo. It sounds just fine if i put it on auto.

This is just going through the tv speakers which is set to have surround sound not sure how since it has just the tv speakers.

Is there anything i can do so they both work properly without fiddling with the options each time i play 1?

Well for the lion king i was able to correct the sound quality by turning surround sound off on the tv. So now the emby client is just set to downmix to stereo. Seems weird though that if i leave it set to auto that it cant play 101 dalmations 2.

Ok, i will try to get some time with the tv wednesday and see if i can reliably re-create the issue. I hope something shows in the logs but i am not sure anything will. It acts as if it is playing but there is no audio or video when this happens.

Thanks. Once you've done that then we'll see what @@ebr thinks. Thanks !

Ok, i finally was able to play with it a bit. If i set audio to auto on emby client and i go to play 101 dalmations2 not only does it not play it claims it cant reach my server. To correct i force closed the emby app then went into the emby app again. Switched to downmix to stereo and i can play 101 dalmations 2 without issue.

I started this test at 9:34. Uploading the log and sending via client.

So, any idea what is happening on this? I am not too worried about it since there is a easy work around and i dont care much if its stereo or anything else.

What is the name of the local Emby server?

 

Never mind, I think I found it but I only found one log and it is from the successful playback attempt.

It is named Home-Media.

I can try again next Monday if you need me to.

The one odd thing that stands out about that track is that it is 4-channel AAC.  I'm not really sure which 4 channels it is...

I downmixed the audio to just stereo for 101 dalmations 2 and it plays now without issue.
