Multichannel music doesn't play correctly

[Richard Branches 330]

Besides it also gets downmixed to stereo as on Android and Tizen, playback stutters and it freezes at some point, here's a server log, perhaps it provides any useful information about it.

Hi, I guess what you mean to say is the LG audio player doesn't handle it very well, right? What format audio is it?

Yes, it appears to be the case.

Forgot to mention it's FLAC. Do you need a sample file?

[Luke 42077]

Do you know that it's something that the TV supports? Perhaps it shouldn't be direct playing.

There is no transcoding involved but it may be possible that the TV doesn't support it in some way, if you don't see anything unusual on the log then I will have to test the internal player by connecting a USB dongle with a song to see what happens and then report it to LG.

Yea the one thing to keep in mind though is that that is not guaranteed to be the same result. It usually is very close but we have seen discrepancies.

 LG webOs apps are based on chromium, which has its own embedded ffmpeg build for playback.

When you play with usb we don’t really know if it plays with the same components or not.

I finally tested the internal media player of the TV and the multichannel FLAC files played without stutter but they were downmixed to stereo.

I made the test after a firmware update arrived to the TV, I can't confirm if the issue was happening before.

However, the Emby app doesn't play the files after the firmware update, it use to play before with stutter, now it doesn't do anything, this is on the latest 1.0.50.

Please let me know if you need a log from the server.

We might have to disable flac for audio playback, but that won't make some people happy.

What TV model? Can you post the full media info and server log with a playback test

It might be worth waiting in case you get another firmware update to confirm that LG don't resolve this.

Keep in mind that LG support is only 2 channel flac

I prefer to share a file sample: Blondie - Heart of Glass.flac

As I said above, the internal media player of the TV plays those files without stutter or anything but they just get downmixed to stereo which is what the TV does by default.

Yes, I know, the problem is, playback stutters and then it just stops indefinitely after a few seconds (this time it stopped at the 10 second mark) and the UI stays frozen until I press the stop button.
