Hi,

Please try these steps,

1 go to Control Panel

2 go to Device Manager

3 go to Sound, video, and game controllers

4 double click the IDT High Definition Audio CODEC

5 go to Driver on the top of the IDT screen

6 click Roll Back Driver...yes it takes away the most recent update but it worked for me

7 after it is done rolling back go back to the IDT screen and go back to driver and click the Update Driver... button...don't interrupt it let it do a search and update

if after those steps your audio still doesn't work properly then i cannot help any further

hope your sound comes back

Good luck!
