  1. The third one did it for me! 16 bit, 48000 Hz was the sample rate by default! Changed it back to is 16 bit, 44100 Hz and it worked alright!

    Thank you so much! 🙂

  2. Solution 3 for me – had to adjust the sample rate after taking the Win Anniversary update made my guitar rig quit working

  3. Hey thanks, restarting Windows Audio from the services was the silver bullet that got my bluetooth speaker to work. Y’all rock.
