The issue is on my Samsung TV UN43MU6100.
Software version: T-KTMUABC-1290.3 (up to date).
YouTube app version: web_20210913_08_RC00.
I reset the app through YouTube settings to see if it would help. Same issue.
Factory reset the TV. Same issue.
Any "YouTube Music playlist" or "My Mix" or any channel that has " - topic" as suffix won't play. It shows the cover of the song with a buffering logo for a few seconds, then the error.
Error: Something went wrong. Unknown Audio Playback Error Playback ID: 7Z5Jc_UVySu3dZwf
ID changes depending on the video/song, obviously.
Software version: T-KTMUABC-1300.3 got rid of these issues
Same software version but these issues are back, could be because of an update from youtube app. Not sure.
It might be a coincidence or a deliberate plan but the fact that Apple and Samsung inked a deal (Jan. 2019) to bring the Apple TV app and Apple Music app to select Samsung Smart TVs does not exactly give Samsung much of an incentive to invest developer resources to fix problems that (Apple Music competitor) YouTube Music has playing on their TVs.
Has there been a solution provided for this yet?
I have a similar issue with my QN55Q65FM tv. I cant identify any pattern in the errors. It appears to be random for me. I have another Samsung Smart TV (UN65TU7000FXZA) and that one plays everything on the YouTube app without issue. It's surprising to see an issue like this with a Q series TV. Apparently they arent as high end as Samsung makes them out to be.
