Mid last year I bought a cheap Sonos speaker from Ikea and it was a huge upgrade to my home life. For the last decade or so I’d almost always listened to music only through headphones. Occasionally I’d airplay a bit through my TV but it sounded pretty terrible.
One problem I’ve encountered is that fairly often the music would just stop and I’d have to restart apps and the phone to get it to play again.
I finally worked out what was going on!
My phone has a helpful feature that switches to a cell signal when the wifi gets weak, which it does in the exact place in my house that I have my speaker. Since I turned it off, the music never drops out.
