This can be frustrating, especially if you are playing an important video file, having a Skype call, watching a movie, or using your headphones.

  1. Thank you very much, you’ve just saved me from re- installing my OS because of these sound issue.
    Thank you, thank you.

  2. i fixed the old problem but now i have a new one, i have wireless headphones and if i move my head away from my pc it wont work.. how to fix??

  3. I have tried all three of these suggestions, and none of them worked. I can see on the onscreen audio mixer on OBS that audio should distinctly be left and right, but it plays only in mono. Additionally, if I record audio that is panned left (and shows that way on OBS) or panned right, when played back (even on a different device) it is in mono. It is as if Windows is converting the audio to mono before recording in addition to playing back stereo sources (like stereo channel checks) in mono.

    Thanks for any help anyone can provide.

  4. I have a tablet with windows 10. I want to record internally in stereo. Records on one channel only with microphone included. Do I need a sound card or cannot I download an app to do this?
