OLED C8 - Kanto YU6 Optical Out Popping

[xajin]

Hi all,

When connected via optical toslink cable, I am only hearing a constant popping noise, and also a high pitch whine. When connected via bluetooth or just using the internal speakers, everything works well. Has anyone had a simular issue or a suggested fix? I've tried both optical 1 and 2 ports in the back of the speaker.

Probably a dumb question but have you tried another cable?

@George Hofmeister yeah I’ve tried 2 different wires.

so I found out that if I chose the “internal + optical output” audio option, the speakers work fine. I also tried going to the “connect device” setting, then to “sound bar” (this seems to be only option with optical), I’m able to play the test sound perfectly, but if I choose optical only, I get the static grindy noise.

one last odd observation is that if I use the built in YouTube app on webos, I can play sound just fine with “optical” only option.... but will have problems with all other apps (Netflix, amazon prime video, plex)

Issue was solved by changing the Audio setting to "PCM" from "Auto". Everything works as expected now.
