I am trying to use a pair of Sony WH-CH500 bluetooth headphones in headset mode with a Lenovo T480 laptop. They work perfectly fine in stereo headphone mode but the moment I enable the headset from the sound settings the audio cuts out completely.
The T480 has a wifi/bt combo Intel® Dual Band Wireless-AC 8265 chip.
These headphones obviously work with my phone and they work with a different Asus laptop. Perhaps what is really surprising is that I installed a trial version of IVT BlueSoleil software on the T480 and once I paired the headphones using BlueSoleil they work as expected: stereo headphones when listening to music and automatically switch to headset mode when I receive or make a Skype call.
The headphones work, the laptop's hardware is capable (otherwise it wouldn't work in BlueSoleil) so why don't they work without BlueSoleil software (which I can't use once the trial ends)?
I tried installing drivers from lenovo, drivers from intel, purged both and tried using whatever driver windows installed by default and no luck.

Did you follow the Sony guide exactly for the setup: https://helpguide.sony.net/mdr/whch500/v1/en/contents/TP0001613466.html . I generally only use Lenovo Drivers on Lenovo Computers. Try running Lenovo Vantage to see if it can update the drivers with Lenovo drivers.
