My soundcard dosnt work!?

My micsometimes work and does not, when it dosntit makes buffers noises all the time and sometimes as said it works, somebody had the same problem? _) Thanks for helping btw.

Maybe it's not plugged in properly or Windows doesn't recognize it, make sure whatever you're using is set up properly.

maybe install pilot , and verificate if there are not broken

I'd check your device manager and uninstall and reinstall the drivers.
