I am trying use the input on the back of my PC with my little mixer. I am using a stereo 1/8" plug in the pink socket. Sound from this device is hit or miss. It works fine on an older AMD machine with integrated graphics. I can see that Windows "sees" microphone input because the little blue bar moves in the "Sounds" area in Windows. But it sounds like absolute garbage or has a bit of delay on input. I having a suspicion that my AMD video card is causing issues. This is a brand new entry level HP gaming computer. Anybody else hear of such a thing? Here are some of my specs:
AMD Radeon™ RX 550 Graphics (4 GB GDDR5 dedicated)
•Erica AMD B550A
•AMD Ryzen™ 7 3700X
