I am currently using M.B. MSI-6368 which comes with onboard audio VIA AC97 codec running on XP professional edition. It was no problem with the sound output so that I can hear default welcome windows sound and all of CD, MP3 audio. The latest audio driver is what I am using is ver126.96.36.19970 VIA. However, when I want to try to record sound via microphone, it doesn't work. I had another machine got the same problem with same on-board VIA AC97 audio. I did check the control panel sound setting, I am for sure the mic volume control is not mute. But I can't playback the sound I recorded even the sound driver seemed to work for output sound. Does anyone has the same issue?? I did also try to both enable & disable BIOS legacy on-board audio but still no much help. Please let me if anyone has the same problem with using on-board VIA AC97 audio, thanks!!
