No.  What I do know is some mics only last so long.  I've had 2-3 low-end mics die in a row.  If one pays a little more for a better mic, it's not just better sound quality they're getting, but something that lasts longer. You know how sometimes some music artists drop the mic?  It's discouraged unless they own the mic because that can kill it.
The audio works just fine on my friends Optiplex 9020 and the microphone was working fine for weeks after he bought it but it just broke and doesn't work. I've tried everything I can think of to fix it and I'm stuck. I tried installing wave maxxx audio pro and it would install but it wouldn't launch and as it couldn't load because of an outdated windows update so we updated it and still, it didn't work. Any ideas? Any help is greatly apricated!!
