Arc TV sound cuts in and out.

Hi all,

Glad I came across this.

Mine has been working 100% perfect and still runs fine on Netflix, Disney+, std digital TV.

The first time I tried to use the Nintendo Switch I noticed it cutting out. It does it constantly and is worse the more is going on the screen at the time.

I have a OLED55B9PTA running eARC

It’s funny that you mention the Nintendo issue. Mine didn’t start having problems until we started playing on Nintendo Wii. Had family in town and we played mario kart and immediately started having issues. Xbox and PlayStation work fine. Why would that be?

Posted earlier on this issue.  After all the connection issues I gave up, took the system back to BestBuy. 2 days later I got a Bose 700 (because it is also white). Using the ARC connection, I have no drop outs on the Bose, which were not related to the source, which points to the sonos.  Noting that both the Bose and Sonos have difficulties reconnecting back to the TV system after using airplay.

The Bose has to also go back because it appears to be a referb unit, rather than new?

I would probably swing back to the sonos if there were any signs of a fix?

I have an issue where the audio cuts out on DTV when I change channels.  Have to turn TV on/off to reestablish audio, then problem will resurface almost immediately after changing channels.

Setup is Sonos arc, LG 86” UN8100PTB (which is new), using HDMI eARC.

I changed TV setting to disable eARC, i.e. using ARC, problem solved.

Obviously wanting benefit of eARC, re-enabled eARC and explored other solutions. 

Changed TV audio output setting from Auto to Pass Through, problem solved. This doesn’t make sense as the pass through should only affect external audio sources, such as BluRay etc.

I’s continue to monitor and see if problem reoccurs.

Did create my own thread on this issue but best to use this thread, I thought I had solved it by changing HDMI cables, but issue persists with audio dropping when exiting internal apps or external devices back to tv tuner.

Also I sometimes get a quick 1 second audio dropout not long after turning tv on, while on tv tuner.

Also for the first time yesterday I was watching the freeview tv tuner and the sound just dropped altogether after a while, I had to switch to another HDMI port and back to tv tuner to get sound back.

TV is new LG CX, and I use eARC and passthrough settings.

Clearly something wrong with this ARC, please Sonos, sort these audio issues out.

Just purchased the 2020 Sony X900H 85” for our media room. Paired it with the Arc and Sub (gen3). While watching a movie, or show, the sound drops intermittently - the rest of the family doesn’t notice it that much, but it is annoying the heck out of me.

Not sure what to do - getting frustrated, and close to returning the Arc and Sub.

Latest research my end:

S2

Arc

eArc

Sony 65 X950G (2019)

Auto 1

My sound cuts out when using Tidal app and streaming Dolby Atmos content and returning to other Apps like Netflix, YouTube, etc. 
 

Switching to Auto 2 fixes the sound. But I’d rather not switch back and forth. Rebooting also fixes it. Then I can switch back to Auto 1. 
 

Still not sure if this is a Sonos problem or a Sony problem. I will be reporting in this in detail in our upcoming three month follow up review. 
 

Other than this nonsense, the Arc is a superior product. 

I was having the same problem with a Samsung TU8000 and fixed it by going into the audio expert settings and disabling then re-enabling the Dolby Atmos Compatibility feature. Didn’t have to disconnect the hdmi and the problem appears to be fixed for now.

I wonder if anyone has a 2019/20 Sony fix? The problem’s obviously widespread. Thx 

No - I have the 2020 X900H and it is not solved.
