Run the Registry Editor, open HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ audiosrv, double-click "dependonservice" in the right window, and delete "mmcss Delete" in the displayed dialog box ".

2. Disable the multimedia class scheduler service. Disable it in the Service Manager.

3. Restart.
