I have a PowerSpec 1710 laptop with windows 10, and a pair of Sony MDR-1000X headphones. I've been using the headphones over bluetooth with this machine for months. Normally, some volume between 20 and 40 is sufficient for listening.
Suddenly over the last few days even at 100% the output volume is extremely quiet. Meanwhile, the headset (communications) functionality volume is still as loud as ever. I have confirmed that the headphones work fine when paired to other devices.
I have tried 1. Rolling back audio drivers 2. Rolling back bluetooth drivers 3. Disabling audio enhancements 4. Manually installing audio and bluetooth drivers (note, I'm not even sure if this was successful, because windows automatically installs drivers on boot)
Any suggestions would be greatly appreciated. I did allow windows to automatically search for and install audio and bluetooth drivers before this problem began, but rolling back did not seem to help.
