When I play a music either via headphone or via Bluethoot speakers I hear sound deformations / noise / Sizzles
Some time I also have the problem when I call.
I've restarted the phone and I still have the problem.
Could you try to disable all sound effects and see if you still hear a volume decrease when you play low frequencies?
I installed it but don't have any experiences made yet. We'll have to watch this closely. My guess is that especially short time after the update the issue would appear to be gone but might sneak back later on..
At least the release notes mention bug fixes and better usage of devices connected via bluetooth...
