Hello,

Please install the audio drivers. The cd utility probably enclosed in your PC from the vendor. insert the cd then install all the drivers and specially the audio driver.

I believe the problem is that your mic isn't working properly so follow these instructions:

1: Go to control panel and click on "sound"
2: When the sound window opens click on "recording" you should find the built in mic there in the dialog.
3: Click on your built in mic and click on configure.
4: Then, click on "levels" and set the microphone level to 50 and the microphone boost to +20.0dB

If that doesn't work try doing a system restore.Or you could try restoring the defaults on the sound pref.

If you can play a MP3 music file already, why would you want to record it?
If you want to convert the MP3 file to a WAV file all you need to is use a conversion program.
