Answer 1

Yes you can, but I did not try it myself so be warned, download the .REG file here.

OR

1. Press Windows + R, type devmgmt.msc, press Enter and look for your sound device. (e.g. Reatlek High Definition Audio) Double-click it.
2. Go to the tab 'Details' and click the drop-down list. Select 'Driver key' and copy the text from 'Value'
3. Copy the text into a word processor (e.g. Notepad)
4. Replace all lower-case letters with capital letters and remove the \0000.
5. Open Registry Editor (Windows + R > regedit) and locate HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Network.
6. Create a new key (Rightclick > New > Key)
7. Copy the text from your word processor and paste it into the key name.
8. Edit the '(Default)' key and type 'Sound, video and game controllers'.
9. Create a new key called AudioEndpointBuilder, MMCSS and Audiosrv
10. Edit all their (Default) keys and type Service.
11. Restart your computer
12. Go to Services (Windows + R > services.msc) and start Multimedia Class Scheduler and Windows Audio Endpoint Builder.
13. Then start Windows Audio Service
