Hello guys,

hopefully someone can help me out with this one, otherwise this soundbar is going back tomorrow.

Soundbar name: OK. Soundbar OCS 120BT-B

I got the soundbar yesterday and everything was fine, but today I have noticed a high pitched sound starts after a couple seconds of playback and stops a couple seconds after the music is stopped. The sound comes out only on the left side as far as I can tell.

I have tried isolating the optical cable and removing the cable and connecting it to my phone through bluetooth. Same noise, but it stops quicker on bluetooth when music stops.

I have just figured out that if I leave Spotify running but mute it from Spotify, so that no sound is coming out but music is still playing, the whine is present.

I think it happens when more power is fed to the speaker to play the sound? Maybe they go in some kind of "standby low-power mode" when nothing is playing.

What do you guys think and what can I do about this?

Thanks for taking the time for me!
