Audio Problem

[fallenknight308]

I have just the basic audio "in", speaker "out", and a mic "in" on the back of my pc.
My problem is when I use the mic-in or audio-in I can't hear anything coming from my speakers.
I have gone into the audio properties, and checked that all input sources and volume ect... are in order,
But still nothing. I have also done the voice-test in the audio properties and can hear my voice through the delayed tester, so then I tried using my .wav recorder and found that I can RECORD sound and play it back, but cannot HEAR sound WHILE recording or just speaking into the mic. My audio input has the same problem. I was able to hear through them before, so wtf?
This is really pissing me off, as I like to play my guitar through the pc, and HEAR it before I start my .wav recording. same with the mic.
Is my output hardware bad?
Any help would be great!!!!!!!!!
