Hey! 
Do you also have WIndows 10?
Then you need to go to the control panel. The easiest way is to do a search and type “control”.
Then go to “Hardware and sound”, and then you see the driver atr the bottom. (Don’t go to Audio devices or anything like that.)
There click on the first tab (with the name of the sound card), and there you can hange it.
Good luck!
