1. Open Regedit.
2. Browse to the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\4d36e96c-e325-11ce-bfc1-08002be10318
3. There will be multiple folders in here named with numbers; 0000, 0001, 0002, etc. Click into each one, there will be one with a reg key named "Driver" and the value "IntcDMic.sys".
4. When you find the one that contains "IntcDMic.sys", expand the folder structure and browse to "Global Settings\Device0".
5. In Device0, look for a key named "Gain". Double-click it or Right-click and choose Modify, then change the value to "a0000" (without the quotation marks).
6. If there is no key called Gain, Right-click in the window, go to New, and choose DWORD (32-bit). Edit the new value so Value Name = Gain, and Value Data = a0000
7. Click OK, close Registry Editor, and reboot the computer.
