I play a video and the sound stops working after 5 minutes. I launch a game and sound stops working after 5 minutes.
Restarting the Windows Audio service via services.msc re-enables sound for another 5 minutes, then I loose sound again.
Testing the playback sound device in sound options returns "Error! Failed to play test tone."
I am using a Lenovo U330 notebook.
I found articles dating back to older versions of Windows with similar problems, but I have yet found a permanent fix that resolves the issue.
I used sfc/scannow in cmd and it returned errors that it can't fix , but the error log is huge and I can't pinpoint the issue.
How can I permanently fix my sound issues?
