I have recently had the windows 10 april update which was a disaster. I have fixed everything except my bluetooth issue. I use an amazon echo as a bluetooth speaker and since the update sound is very bad there are gaps in sound and quality is poor. Problem is not speaker as alexa sounds fine when used as alexa. When I troubleshoot bluetooth it says check bluetooth radio status . i have googled this and stopped and restarted bluetooth in services but still have problem.
