Sonos beam audio cutting out on TV

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.

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.

I think it’s quite likely the sharp TV is having issues processing some of the audio data in a 'timely' manner, as the Beam will only play the signals that are sent to it and at the the time they are sent.

Looking at some Sharp TV setups and information online, they appear to have these, or some of these, internal audio enhancing features...

• Auto Volume
• 3D Surround
• Clear Voice
• Bass Enhancer

There may be other audio features and some enhancement features may have similar names if they are not in the bullet-list above.

So my suggestion is to perhaps try connecting to the internal TV speakers and switching off some of these Sharp TV audio enhancements and ensure they remain disabled when connecting back to the external Beam HT device.

The hope here is that disabling these audio enhancements may help to reduce the burden on the TV processor and cause the signal to pass to the Beam with less, or no, intermittent interruptions.

I hope that suggestion makes some sense. I think it may at least be worth trying to see if it resolves the intermittent audio dropout issues.

Hunter7891,

I have an old Sony Bravia KDL-40EX503 and that works fine with the Sonos Beam. Do you have the latest firmware? Have you tried a different HDMI cable?

Thanks. I disabled all audio enhancement options with a sharp advisor (none of which you mentioned were auto, but DTS TruSurround was). It still cuts out. I have since returned the beam and got a Sony HT-X8500 which works perfectly.
