My setup: a Mac mini connected to a Vizio TV. I have a Playbar connected to the TV to capture the sound from my mini (iTunes, the SONOS Mac app, Netflix, YouTube, etc.) To stream the music throughout our apartment, I have a Play1 in the bedroom and another in the kitchen; these are both getting a signal from the Playbar (I'm not using my Internet wifi signal to stream SONOS; i.e. it's in "Boost" mode, as you guys call it.)
My problem: sound from the Play1s will randomly cut in and out. There doesn't seem to be any discernible pattern to it - it happens at various times throughout the day. And sometimes it'll go for days and work flawlessly, then one day I'll be streaming some music and the 1s will cut in and out. When it's happening, it seems to happen once every 30-60 seconds and the drop out lasts for a second or two, then resumes playing.
The Playbar sound does not drop in and out (it's hardwired to the TV, so no surprise there.)
The closest Play1 is probably less than 20 feet from the Playbar, with almost zero visible obstruction, and the second Play1 is just around a corner from the first, maybe 6 feet away from it.
My Internet router is an Apple Airport Extreme. It's sitting 17.5 inches away from the end of my Playbar. It's putting out a 2.4GHz signal and a 5GHz signal, set to choose the channel automatically.
My SONOS is currently set to use Channel 11 (because I had a problem a month or two ago where my speakers disappeared and the only way I was able to reconnect them was to change the channel they were operating on.)
I submitted a diagnostic report and my conf # is 6999376.
I'm sure this question has been addressed somewhere by now, but after about half an hour of digging through the archive, I gave up and decided to submit a new question. Thanks for any help.
