I have a computer that has a mic issue. I have a Geforce GT620 installed and my monitor is being used through the HDMI port in the back of the card and i have a PPA 1424V sound card installed (it can be found at this website http://ppa-usa.com/computer-products/sound-cards/pci-sound-card-8-channel.html) i am using the front panel connectors via the passthroughs that the case uses. the passthroughs are plugged in the sound card. i am using a cyber acoustic headset (sorry cant remember the model) and the sounds are going through the speakers in the headset but i cant seem to get the mic to work. i have also tried doing it with multiple headsets and all have the same results. when i go into the control panel there are 3 mic options. the one with the envy24 WDM is set to default and the others don't seem to work either. they are Line in also with the envy24 and there is the high def audio device. i have tried using skype and windows sound recording to capture sound and have others hear me. and when i go on http://www.systemrequirementslab.com/cyri it says sound is comeing out from nvidias driver. so... im stuck and would really like some help
