Sound Card help, Sound Blaster X-Fi

My boyfriend just bought a new sound card because the first one he bought wasn't working.

He's trying to use it in Teamspeak but nothing is working (He has the headphones hooked up but his voice doesn't work. *I made sure he had it turned on*)

He bought the Sound Blaster X-Fi and installed it, he uninstalled the first one through the control panel. (maybe not the correct way but he wouldn't wait for me to look anything up.)

Everything seems to be up to date but he can't record any sound. (had him try recording with Windows Sound Recorder)

He would like to be able to talk on teamspeak...

- He still needs to test everything in DirectX Diagnostic Tool. (but he's looking at other things at the moment :/ )

Is there anything that he might have over looked?

(I'm posting for him because he doesn't have an account here, and well I figured I get more help here than anywhere else.)

If there is anything else I need to find out, I'm more than happy to get that information. Also thank you for the help.

 

what card was in there before? ive had driver problems with creative cards before and fixed it with a "clean sweep" as the creative techs call it. here's the link: http://ask.americas.creative.com/SR...48,VARSET=ws:http://us.creative.com,case=1712
and go to the PCI Sound Blaster tab

 

Thank you, I will try this tonight. This will probably most likely be the problem.

He wasn't being very smart when he installed the previous one.
He didn't uninstall the very first one when he put the second one in. Then he got this new one and uninstalled (because I had to lecture him). So this is his third sound card.

I really hope this helps.

Edit to add:
The 1st sound card was a Creative Suite along with his 2nd One. So I'm pretty sure they have all been Sound Blasters.
