I’ve read a lot of posts regarding similar issues to mine but none identical. I have a classic Sonos surround set-up with the Beam, run from a Samsung TV on HDMI ARC, which works perfectly most of the time. However when viewing advert supported channels e.g. My5 and 4OD I get a loud buzzing from the Beam right channel toward the end of the advert sequence or when the programme restarts. It’s like there is a change in the audio coding used by the ads which triggers it and the only way to stop it is by power cycling the Beam. I submitted a diagnostics report hoping for some advice: 691378500.
