This has only happened 3 or 4 times since setting up my system 4 months ago. But it seems to be getting worse.
My master volume on the phone app has just slowly increased to max volume by itself! Once this turned up my Playbar, Sub and 2 Play 5s to MAX VOLUME downstairs as I was walking upstairs and connecting to my Play 1 in the bathroom. Needless to say my wife (and 6 weeks old daughter) were not overly impressed with this new feature.
I've also found on occasion that it just turns everything down and if it try to turn it back up it just goes back down.
And I've also once had it smash up to max volume and then the app gives me the buffer load wheel and i cant turn it down. It feels like SkyNet is getting in there and trying to destroy my families ears.
This is a very annoying issue for a $5000 home HIFI rig.
Any advice on how to stop this happening?
