Hello - I have an Atom with KEF R3’s and then 2 Mu-So Qb2’s. The Atom is hardwired and the Mu-So’s are run over the Wifi from a TP-Link Archer AC1750 router. I am steering the system with the Naim app on an iPhone XS. Everything is updated to the current firmware and software version (except the iPhone, which has iOS 13.4.1). I have checked the WiFi strength all around the Mu-So’s and it is generally >200 Mbps both up- and downloading (on a 5GHz network).
I have generally poor quality pairing with the Mu-So’s. For example, when running “multi-room” to pair all of the speakers, I have an issue in which if I adjust the volume slider for either of the Mu-So’s, it spontaneously reverts to its previous setting. This means that I essentially cannot control the volume through the app. If I reboot the Mu-So, then it tends to function for a few hours, but the problem quickly returns. While trying to get it to work today, the Naim app crashed twice. In addition, sometimes when playing “multi-room”, the volume slider for one of the Mu-So’s disappears. In the app, it shows the speaker as green checked and music is still playing - but the volume slider is just gone. Again, a reboot will generally bring it back.
Has anyone experienced anything similar? This is driving me nuts.
