HomePod Pops, Farts and Restarts 🥴

Hi - my HomePod isn’t well 🤔😬

during playback, or when silent, it has been making a “popping” sound - just like a legacy speaker+amp setup makes when the power is switched off/on

most recently, during playback only the HomePod regularly makes a loud “farting” sound and restarts itself...

anyone had this issue - it’s out of warranty so Apple unlikely to replace but I’d love to fix it if anyone knows how.

thanks in advance
