So i wake up and start my computer and noticed that my sound is very low. I checked to see if the tabs are all at MAX and they are. Tried some things, installed new drivers, uninstalled them again and nothing helps. I usually use Microsoft High Definition Audio Device because it fits my 5.1 Roccat Kave headset. I tried with other normal 3.5mm headphones same resault. Sound is like on 20-30% despite its on 100%. I rly need some help. Yesterday i had no problems. Im running on Windows 7 sp1, I can provide pictures if needed just to solve my problem. Thanks!
