Big Sur sound settings disconnect bluetooth keyboard/mouse
I'm using a new Mac Mini M1 with Big Sur.
Whenever I go to sound settings my bluetooth keyboard and mouse are disconnected for about 30 seconds. This happens only when going to sound settings, either via top-menu, control-center or system preferences\sound.
I have previously used the mouse and keyboard with a 2009 iMac 21,5". Battery level is 100% on both.
Any suggestions?
