I know it sounds utterly ridiculous, but there are ants living in my Sonos PLAY:1. As there's no easy way of opening it up, I can't try to kill them all, but they are constantly crawling out, and also seem to leave behind little black flecks of something. I assume they're eating something in the speaker (maybe the rubber?).
Not sure if anyone else has had this problem but would love to hear from you if you have and have any advice, as I'm worried that the sound quality will start deteriorating as they eat away at the speaker.
I've not had much luck with turning it off at the mains and leaving the speaker to cool down. They're still in there.
FWIW I'm in London, UK, and it's getting into winter here - so it's not as though seeing lots of ants in any situation is a common occurrence, which makes this even more bizarre.
