Make darn sure the MIC is connected to the right port. Under the bios, there should be at least an "enable" for the build-in sound/audio, though I thought there is one for MIC itself. I suggest you reload or find the proper drivers for the sound/audio which in turn will enable the MIC side. These are probably offered in the mtrbd. driver CD if you have one. If not, get the latest driver(s) from the support website from Epox for your model mtrbd.(make sure of model) and get the sound/audio driver and for the XP OS usage. If you still have problems, maybe the cable to the mic or the mic itself is bad, it does happen. Also, the under the multimedia icon under the control panel that the mic isn't "muted" or at a low level. Also, that's a good place to see if even it is installed or selected.
good luck -----Willy
Problem: Microphone is not working. Speakers are working. Line-in volume is activated, sound device is working properly according to XP but mic test fails.Tried 3 different mics.
Been told that BIOS sound for mic might be disabled.
Can this be correct and how do I fix it?
