Sounds like there’s just enough wifi interference to occasionally break the signal connection between the PLAY:5 and the PLAYBAR. I’d be reading that linked FAQ, and seeing what potential solutions can be applied. 

Hello @Mbaymadsen, having dropouts in such a short interval is definitely not a pleasant experience. As Airgetlam suggested, this could be a cause of wireless interference.

If you are not able to find a solution from our support page, I’d recommend you to submit diagnostics within 10 minutes of the issue occurring, write down the confirmation number and get in touch with our Support Team for more in-depth troubleshooting - they have access to more tools and will be able to perform live troubleshooting with you.

Thank you both for replies. I have looked at the wifi interference troubleshooting and nothing seems to work out. If I reboot my router just before I airplay from my appleTV it can keep the connection between the two speakers most of the time.

Nothing has changed in my setup or with new devices on the wifi so I wonder why this issue has occured.

I would maybe follow the Staff advice/suggestion above by submitting a system diagnostic and speaking with Sonos Support Staff to try to get the issue resolved.

Note that all wireless interference doesn’t have to come from either your own network, or even your own home. There are lots of changing influences on WiFi networks at all times.
