Hello. I have a beam 2nd gen, sub 1, a pair of play 3s. It has been working fine until I noticed stuttering on just one of the play 3s. Regular music seems fine. I tried reboots, unplugging tv cables, arc. The fact that it used to work this morning and doesn't makes me worry it is an issue with the unit itself? I tried different output modes on the tv. Had the issue with auto and direct. Dolby and dolby plus didn't seem to output through my surrounds properly so couldn't hear stutter. Everything is hard wired. Seems like the recommendations are to reboot routers and factory reset? But why just an issue with one speaker and not the others? Also if it is just atmos but music seems fine, maybe software?
