Just to add, I've sent a diagnostic report not sure if the playbar issue will show or if it will help.
Have you perhaps tried removing/reseating the optical cable (at both ends) and ensured the ports and cable look okay, no kinks in the cable etc.
Yes tried that, the cable looks fine no kinks.
If you’re hoping a forum moderator will look at that diagnostic, it may help if you were to post the number in this thread.

Does the high pitched noise stop if the optical cable is unplugged?
If the whine is present whenever the Playbar is powered then the switched mode power supply has most probably developed a mechanical fault. It’s likely that the disturbances during the house move caused this. The best course is to contact Sonos Support by phone.

Had a playbar with a surround setting with gen 2 sub and play 3s now at new home with play ones. As soon as i plugged in the playbar, high pitch noise appeared.
Read other posts, is it possible to correct this problem?
Any help with this would greatly be appreciated .
Is there no support at the weekend to help with product issues.
