I bought a pair of these second hand just over 2 years ago as a degree completion present. I set them up for him and they have been fine and he mainly uses them in PC mode as he records and produces in his (expanding) spare time.
Anyway he was complaining of a intermittent buzz so I decided the first thing is to get in the latest firmware. It took a few goes, not working on his Mac but my surface pro did the update with one slave speaker error.
Now the app connection floated in and out so I did a factory reset. Now the control app connects okay but I cannot seem to get the sound settings to work. Once I go to this screen it try’s to connect with spinning circle and then says cannot connect. The streamer app works okay and all other aspects of the control app.
Any ideas on this issue? Is there an incompatibility with the new app and an earlier speaker and if so how do I change the sound settings in the expert mode?
