Hey iPReCuRSoR,
I'm sorry you're running into that sound issue. Have you tried the above suggestion yet? What is your current audio driver version?
You can check your current audio driver version by:
1. Press the Windows key + X
2. Click Device Manager
3. Expand Sound, video and game controllers
4. Double-click on IDT HD Audio
5. Click the Driver tab and let me know what version number is listed there.
