I cannot get any sound when I do the echo check. I have gone to 'audio setting' and have switched to 'line in high definition device' with manual settings, BUT..I can hear 'her' just fine but cannot hear my own voice!! Please help!!
does your mic work in other applications? first, try to upgrade your microphone's driver (you can visit the manufacturer's website to see if there are newer version of driver/s for your mic).
