I have onboard sound from asus a8n-vm motherboard and an sb live 32 card. I have a mgicjack phone usb as well. I got the magicjack working fine for phone service. What I cannot get up is microphone from either onboard or sb jacks to work with my headphones set for online voice chat. I've tried looking for a setting that could be muting the mic but cannot find it. Settings for speakers and headset work fine for playback, I just cannot get microphone to work.
I have windows 7 home
