I am having some issues with my 5.1(Playbase + 2xPlay1). Playbase and AMP are connected with ethernet cable, and both play1s are connected via WM0, supposedly SonosNet.
When I play Amazon music/Audible and internet related services, both Play1 works fine; however, when I watch TV with Optical Audio Cable to Playbase, both Play1 players have intermittent interruption, as if the network is not working properly.
I've tried different channels, 1, 6, 11 but none of them seemed to help. I do have another set of 5.1 in another room, which consists of a Playbar, two Play1s and are connected via Ethernet except for AMP. Sometimes the play1s in question would connect to the Playbar; I tried to reboot the Playbar to force Play1s to connect back to Playbase, but in terms of the interruption it didn't help.
I tried to have the wired Play1s in the other room to play what is coming from the Optical Cable, and it worked very well. I am not sure if I should get an additional access point and try to fix it via additional network overhead.
As a side note, I've reboot all my Sonos and reset those two Play1, but no dice.
Any suggestion would be appreciated, thanks in advance.

When you say AMP, do you really mean SUB?
I think that you might have a source of 5Ghz interference, which is what the surround PLAY:1s are using when they're being used as Surround speakers. I believe they use 2.4Ghz when they're being used for music purposes.
As a test, can you connect them to your PLAYBAR with ethernet cables? That might be a good way of determining if I'm correct.
However, you've already done several of the recommended "fixes" by changing the SonosNet channel. as well as rebooting and reconnecting, but I'd urge you to re-read the FAQ on interference, just in case it tickles something in your mind: Wifi Interference FAQ
But at the end of the day, I'm just guessing. You may want to submit a system diagnostic, and post the number here, for the folks at Sonos to look at. If you do it within 10 minutes of experiencing one of the cutouts, it should make sure that the issue will show up in the logs that are submitted.
