I had a mic that worked with my PA, so I went out and got an XLR to 1/4" cable and a 1/4" to 1/8" adapter, and plugged them all into the microphone jack on my sound card. however, the mic is not detected in Control Panel, and it will not work at all! I've tried rebooting numerous times already, plugging and unplugging, turning switches on and off and the like, but nothing helps. Any suggestions?
