Arc TV sound cuts in and out.

758 replies

Just got the Arc and have it paired with 2 Play:1’s and a gen 3 sub.
Samsung Q80R tv.

The sound from the tv will play for around 5 seconds and then cut out for around 1 second, play for 5, out for 1, on and on.

I’ve swapped out the hdmi cable twice, tried unplugging the tv, switched between PCM and DD+ and switched between different apps on the tv.

The sonos app shows that I am getting an atmos signal

Was running a beam with the Play:1’s (but no sub) before just fine.

Not sure what I should try next.

Thank you,

mike

Thank you all for all your efforts and testing. A system update has now been released which also include a fix to this issue (it disables the Sonos “screensaver” on an Arc if connected to a Samsung TV). Please update your Sonos systems. If you’re still experiencing problems after updating, please let us know.

I recently received my Sonos Arc as well and am also experiencing this.

My Setup:

Directly connected to eARC/HDMI to my Sony XBR75X950H
Arc has physical Ethernet connectivity to my Spectrum router (WiFi not enabled)
Firmware is up to date on my Sony television and the Sonos system

I have swapped the HDMI cable and the issue still persists. This happens with any of my streaming apps (Hulu, NetFlix, and Prime). When I unplug just the soundbar, wait for the 10-seconds, and plug it back in, the sound is back.

I will try to use the optical out adapter and see if I still have the issue. The problem is that this very intermittent and not consistent at all. Sometimes the soundbar will work all day and be fine and other times the sound will cut out multiple times a day.

Just wanted to update everyone that swapping out to the optical out adapter seems to have resolved the issue of the TV sound cutting out on my Sony TV. I did see a few posts asking about music and I was able to stream music without any audio issues (AirPlay). Seems like this is isolated to the HDMI/eARC as the cause of this issue. The only downside to using the adapter is that now I have to control volume through my phone or an additional remote. Hoping Sonos has an update soon!

I am a dealer and I have had some issues with audio as well on the Sony A8H model. I used the optical adaptor to bypass the HDMI ARC from the TV to verify it is not a EDID issue. The customers Audio still drops from using the TV apps as well as the HDMI input from the cable company. I spoke to Sonos tech support yesterday and they said they are working with Sony. They did not say however hows fault this is nor did I get a time frame on the fix. I have my customer bypassing the ARC altogether to see if sound still cuts out from TV speakers.

Ok, unplugging and plugging back in the Arc fixed it.

go figure.

Just want to say I had the exact same issue on a Samsung TV. This solution worked for me as well.

Thanks for the reply. However I have to unplug and plug in the arc everyday. I don’t think that’s right. Go figure!

Um, I’m not paying $800 for a sound bar and un plugging it and plugging it back in every 3-4 days so it works without disruption.

i need a fix.

now.

Same problem, here. Among other problems.

Long time Playbar user. Zero problems.

Intermittent cut in sound. Wall mount. Under Sony 65” X950G (2018). Stock Sonos cables. eArc connection.

Hope there’s a simple fix.

Had the same problem with both Arc and Beam on Samsing TVs. I switched to using the optical cable on both and the problem has stopped. At ;east no sound drop out. Creates a hassle with using the remote to change volume, but do that with Sonos now.

Are they using the Sonos supplied HDMI cable? I have read that they possibly have a bad batch of HDMI cables as well. I am using another HDMI cable + the optical adapter and I have not experienced any more cutting out issues for over a week now. I also noticed that my Sonos system has updated to 12.0.3. I tried eARC again on 12.0.3 but ran into the same issue of the audio cutting out so I swapped back to the optical adapter. Good to know that Sonos tech support is claiming they are working with Sony on this.

Optical seems error free. But opposite one of the reasons I bought the Arc—for the eArc, single remote with Sony native apps, etc.

Switching from Auto 1 to Auto 2 or PCM returns the sound. Really odd.

Has there been an update that don’t know about? All of a sudden mine has been worked my perfectly. Two week straight and no further issues. Prior to that my ARC was cutting out every 3 seconds until unplugged and plugged it back in. Would do this once a week. Now I have no issues. Fingers crossed.

I have Samsung Q8DT TV 2020 with eARC.
