Bluetooth and USB headset issues resolved
This update tests two fixes for issues Windows 10 users experience with Bluetooth and USB headphones.
“Addresses an issue that prevents USB headphones from working on devices that support USB audio offloading.” This problem occurs if you have installed third-party audio drivers on the devices, ”Microsoft explained in Support Bulletin KB5005101.
“Addresses a rare condition that prevents Bluetooth headsets from connecting using the Advanced Audio Distribution Profile (A2DP) for music playback and causes the headsets to only work for voice calls.”
These problems do not appear to be common, but will likely be fixes eagerly awaited by many people working remotely.
