When using the 3.5mm audio output while booted into Windows 10, audio is barely audible at max volume; built-in speakers work perfectly. That is, the volume is very soft when my headphones are plugged in. Windows partition installed through Boot Camp Assistant.
Device: 2018 15" MacBook Pro, Vega 20 GPU.
OS: Tested on Windows 10 1809 AND 1903 (Both fully updated)
Boot Camp Assistant Version: 6.1.0 (6067.230.4)
What I Have Tried:
- Clean install Windows 10 1809 and 1903
- Enable and disable Windows Sonic For Headphones
- Cannot disable audio Enhancements (the tab is missing for some reason)
- Reinstall Mojave
- Reinstall Windows Support Software
Cirrus audio driver does not seem to be installed, but rather Apple Audio Driver. I am assuming this is normal?
Is this a driver issue or a "me" issue. Headphone audio level is normal while using macOS Mojave. Windows 10 installation went smoothly and was uneventful. I did not have this problem on my 2015 15" MacBook Pro.
