Sonos Playbar cutting in & out intermittently when playing music if the audio optical cable is connected to Sony XBR-75X950H TV and the TV is turned off. 

If I unplug the optical cable from the Sony TV (TV power is off) the playbar does not cut out and plays continuously with no problem.

The playbar does not cutout when the TV is on and audio optical cable is connected with the TV sound coming through the playbar (surround sound).

Have you tried unplugging your TV and Playbar from power for about a minute or two to see if it fixes the problem?

I’m experiencing the same issue since purchasing a Sony KD-75X9500H using an Optical cable to connect to my Sonos Playbar. It cuts out for about 3 to 4 seconds every minute or so. My Sonos Move doesn’t cut out, obviously because it’s not connected via the optical cable to the TV.

I’ve checked the optical cable is connected and not damaged. 

I’ve tried power cycling both devices. 

 

As above:

Has anyone found a fix for this? (Other than removing the optical cable which means the TV sound doesn’t work on the speaker!)

thanks 

Not a fix but I did get some workarounds you can try. I haven’t tested the workarounds yet, Sonos support just gave them to me today.

They did acknowledge that this is a known issue with some new Sony TV’s but I didn’t get any info on a resolution before my chat was cut off. 

From Sonos support:

There's a certain issue we've been tracking with some Sony TV's which is causing this. Could you head into the Sony TV's settings and check for software updates if your TV is connected to the internet? 

There are some workarounds that we can apply to alleviate the issue that we have seen work for other users with the same issue. On the TV, could you try changing these settings for us?

I’m having the same issue (Sony XBR-85X950G) - all audio sources play fine on all speakers, except the playbar. If a non-TV source is playing, audio will cutout at the playbar. When playing the TV source all speakers play perfectly. If I unplug the optical cable from the playbar, no speakers cutout.

 Did any of the suggestions work? I’m trying them now.

I would perhaps enable the two suggestions anyway … see the links to the YouTube videos below:

Thanks bud, I enabled the settings yesterday and so far no cutouts. I’ll give it a week and report back.
