Sonos Beam Gen2 Metallic Background

Currently using Sonos Beam Gen2 on Sony 65” TV with eARC connection in HDMI 3. Sounds great overall, but background stadium noise when watching sports sounds very tinny or like through a metallic hollow tube.

I’ve confirmed through the app that it is running Dolby Atmos or Digital 5.1. Settings on (Google) TV are: Speakers > Audio System; eARC mode > Auto; Digital Audio out > Auto 1; Dolby Digital Plus output; Pass through Mode > Auto.

I’ve also messed with several tuning settings in the app, toggling off/on Trueplay, loudness, night mode, speech enhancement, etc. with no major effect on the background noise.

Any ideas on how to fix this issue?

Hi @wtorn

It’s certainly not all Beam Gen 2s that are affected, but that might be part of the problem - if the issue is not originating with the Beam, then a replacement would indeed be of no help. And this may be why it is not yet resolved - if we cannot replicate an issue, it’s pretty difficult to either fix or test then the fix. This is all presumption on my part, however - I don’t know the details of the issue. But, I do recommend that you try one replacement, at least. If that new unit has the same issue, I’d certainly have doubts myself about replacing it again, but at least we gave it a chance.

I hope this helps.
