So the ZP-80 sounds clean and if it comes on can play well for an hour or after few minutes will drop out for half a second every few seconds way about 10 times and then go silent. Might stay silent for a very long time and randomly jolt in a few seconds and then gone again. Sometimes it fades away quickly but less often. Rapid wiggling of the App volume can sometimes make it start to work whilst the volume is being agitated but stops and indeed fades away as soon as you stop doing that.
Loud gain doesn’t improve anything or jar it into working and it doesn’t behave like dry joints.
I have read through forum topics and have done a hard reset on the ZP-80. Turned off the router and all devices and then turned the router on first and the Sonos’ afterwards. Have altered MAC addresses and DNS of nearby Xbox. Not getting anywhere. A 2nd ZP-80 plays mostly fine. 4 other Sonos devices are solid. ZP-80 was 1m away from the router through a wall. Moved it 3m away to try proximity issues. No change.
Diagnostic report: *Moderator edit: obscured for privacy*
Music was streaming from FIP radio during the diagnostic. ZP-80 was low level, lower than set volume, and sputtering/dropping out whilst playing clearly through a 2nd ZP-80 on an ethernet cable and a Sonos One about 15m away from the router.
Local Wifi scans show my router to be the strongest signal by far, any external routers on same channel are far enough away to be effectively attenuated down to no concern.
Connection 250Mbps down, 25Mbps up
Help!
Thank you
