sonos playbar plays fine but starts makes buzzing noise only when connected thru optical, since a couple of days.
the moment that a signal is transmitted thru the optical cable, the Playbar starts to buzz.
And the buzzing is different (pitch) when playing from the TV set top box then when streaming from netflix/youtube.
the volume of the buzzing is controlled thru the volume control of the sonos app.
