Headphone volume broken in High Sierra
Ever since upgrading to High Sierra, volume control only works using the keyboard or menubar controls. Using volume controls on headphones/headsets doesnt work. Anyone have any ideas why?
Some details:
-- MacBook Pro 2017, High Sierra 10.13.2
-- Air Pods
-- Logitech Ultimate Ears UE9000 headphones (bluetooth)
-- Sennheiser PXC5550 BT headphones
-- Apple EarPods (analog)
Regardless of the devices, or the connection (Bluetooth, analog 3.5mm jack, USB), the volume controls on the headphones/headset are ignored in High Sierra. Only the keyboard volume up/down keys and the Menubar controls work.
This is NOT the devices .. volume controls on all of them work fine when connected to an Apple TV or another MacBook running Sierra (10.12.x).
I've tried a PRAM/NVRAM reset, no difference. I'm assuming SOME setting is wrong, but this is pretty much a factory fresh MacBook Pro with a squeaky clean install of MacOS High Sierra.
Any ideas anyone??? TIA
