Hi, I would like to split my audio and have it stream simultaneously. I have the latest realtek driver and I know that my sound card is 7.1 channel. The problem is, when I open up the realtek driver, the main speakers on the rear and front jack speakers are grouped together. I want to separately adjust them. How would I do this? I've read a few suggestions to open up advance settings, but I don't have that button on my driver.
