Good afternoon friends,
I know many of us have had issues with Skyrm, but I have a quick fix for one. This is for audio buzzing/intermittent audio issues, directly from Bethesda. You do not have to delete any saved data or game files, instant fix. Enjoy and let me know if this helps you.

In Windows 7:

Go to Control Panel
Select Hardware and Sound
Select Sound
Choose the sound device that is set as default
Click Properties
Go to the Advanced tab
Make sure the 'Default Format' it is set to 44.1khz 16bit.
