My computer won't work on my computer. I checked the audio settings and it isn't muted. It works on other computers. I have also tried other mics and still doesn't work. In soundMAX Control Panel, the microphone section has an exlamation(!) mark beside it. THhis is in the "Playback" settings. On the "Record" settings, there is no exclamation mark on microphone. Plesae help Thanks!
