This bug is specific to LG TVs with sound bars like SONOS (Where some audio transcoding might have to happen?)

I want to keep the bug reported here alive:

This bug still exists.

I think it was narrowed down that this is because SONOS doesn’t support DTS, so the Plex App in the LG is … causing this bug to happen.

Thanks!

Anyone from Plex care to comment on this?

It’s still an issue. Seems like this setup is pretty common.
