My mic was working fine then stopped the next day

[Epicake]

OK so here's the down-low i have a certified data headset and mic it was working really well one day me and my friend were talking in skype no problems but the very next day we try and talk to each other my mic was giving off no sound and he couldn't hear me i have gone it to advanced properties and everything it might be because of my IDT audio 1 but it hadn't given me problems before is there something i might have missed or done?

The quickest test for this is to first try another mic. If you are quite certain that no settings have been changed then your mic has probably developed a fault.
