Mic/Audio Problems

About a week or so ago, my microphone started buzzing terribly and nobody could hear anything that I was saying. I tried reinstalling the software and a few other things, and all it did was remove any input I had.

I just played around with the 'Test Hardware', and it finally started picking up my microphone. I tried it out, and sure enough my microphone is now working perfectly fine. However, ever since I did this I have absolutely no audio. How do I fix this?

Here's my soundcard if it'll be of any help.

Eh.. not to be a downer but the (older) sound-blaster burn out.. or thats what I've herd. Make sure its plugged in the slot all nice and snug, make sure the drivers are installed. If none of that works, check if its booting up (the card its self). Go into Start>Right click on my computer>properties>hardware>manager>Find the card and look up the info on it, if it has a ! in a yellow circle, that means there is a problem. you can check up on the problem in the menu

 

My sound card isn't even appearing on the list.

 

Would removing the sound card's software and then perhaps reinstalling it help at all?

 

oh wow, thats a problem... check out the drivers.. but for now just use the integrated audio port =/

 

I reinstalled the software and the audio (except for my iTunes for some reason) was working, but the mic wasn't. I then did the Test Hardware again, and my mic was working, but my audio wasn't.

And after I reinstalled the software, my computer started picking up the sound card in the hardware section.

 

Is there anything I can do?
