I have a Play 1 that from one moment to the other stopped playing sounds. This happend from the first time I installed it but since it was in the garden and I didn't use it much I just forgot about it. One week ago i tried using it and it was working, but now it stopped again (with no changes to my home network) and I cannot seem to solve it. I tried lots of solutions with no result. When I change the volume from the speaker I can see the volume bar moving in my phone but no sound will come out from it, it connects to the app correctly and songs advance but no sound from the speaker. I tried:
Resetting the app.
Resetting the speaker.
Unplugging everything from power.
I have a Sonos Beam that when connected to the same ethernet cable works just fine.
Also, I tried setting it up via wifi or without it, but didn't work.
I took the speaker from the garden to the living room (where the beam is), resetted everything but no sound from the Play 1.
The speaker doesn't seem to have a mechanical problem since one week ago was working and I had the same problem some time ago and couldn't solve it either.
