Hello @petervaneerde,
Welcome to the Sonos Community and thank you for reaching out with your diagnostic report.
Is this audio issue only occurring on the Sonos Play: 1 speakers you have in other locations in your home or is it happening on the surround and home-theater devices as well?
Can you try the following steps to see if your playback improves?
Change the Sonosnet channel that you system is using from 6 to either 1 or 11.
Reboot your WiFi router by unplugging it from power for approximately 1 minute.
Reboot all of your Sonos products starting with your Playbar and then your Play: 1s.
When your system is back up online, please test playback on your system starting only with your “TV Room” and then adding other rooms one at a time.
If you respond with a follow up diagnostic report, we can see if there are any changes in the communications data.
