Hey, I have used my Komplete Audio 1 for years with no issues, and then I plugged an XLR Microphone jack into it for the first time just to try out new mic, and I couldn't get it to work, oh well. But now, no sound from my connected speakers, no input is working, no headphones is working. Lights are on, its not a cable or power issue. Did the XLR power short something out? Did some settings change from using XLR? Tried on two PCs.
