My new beam's audio cuts out intermittently, say every 15 minutes, for several seconds on my Sharp smart tv. I only have a beam + tv setup connected via HMDI ARC (no additional surround speakers). My diagnostics number is: 727740947. Any help would be appreciated. I noticed this issue only recently. All cables are in and not loose.

While you wait for a community moderator to pick up that diagnostic for you, a couple of suggestions.

1) Make sure that your TV is up to date on the firmware.
2) Try unplugging the TV from the wall for 5 minutes, then plug it back in. This will force a new HDMI-CEC handshake.

Thanks, but I’ve tried both to no avail. I also switched hdmi cables to be sure the one provided by Sonos wasn’t poor. It still cuts out. I should note like others with a similar problem that the beam works perfectly with no cutting out when playing music.
Was merely a couple of precautionary things, not really knowing what the issue is.

The indication from your last post suggests it's the signal coming in from the TV set itself, since it's not happening on streaming music. Which is odd, since you've got it set up via HDMI-ARC (CEC), in which the Sonos tells the TV set what kind of signal it can accept, and the TV responds by sending that specific signal type (in most cases Dolby Digital )

I'll hope that a community moderator can come in sometime soon and pick up your diagnostic, or wait for you to get in touch with Sonos support and get an answer from them.
