Interesting, thank you for reporting but this is not the intended use of the Aeros solo function, I responded on your other thread, you will be better off using parts and changing between them. The Aeros is likely having a CPU overload since soloing is actually sending 5 mute/unmute commands at once.
I can forward this to the developers but I would suggest using multiple parts and setting Change Part device setting to Immediate to switch to each drone
