I know this is going to sound basic, and lame, but I did have this happen to me once and I fixed it by updating my audio drivers.
Check which audio device you have:
- Press Windows Key + Pause.
- In the window that appears, select Device Manager.
- Click the Arrow next to Sound, video and game controllers.
- Your sound card is in the list that appears.
- Right-click your audio device (mine is Realtek Digital Output) > Properties > Driver > Update Driver
- If it’s unable to update, you can look in the internets for one and download it. Make sure you’re grabbing one from the official website though.
Obviously you may have already tried this or know you’re up-to-date but thought it was worth mentioning.
