At least this beta brought back the volume and audio quality of my Bluetooth earphones to the level it was two betas ago. It drove me crazy how I had to consistently raise the volume to nearly 50% lately when previously I was 3 notches down from that level. I thought it was my hearing or maybe something with the earphones - I hadn’t quite connected it to the beta updates until just before updating to this latest beta. Turns out it was Apple fooling around, it is now fixed for me. 😅
