I tried this on two mics, my zalman clip on MIC, and my apple ear buds to see. Both of them are not working, but both are working fine on my phone. So I came to the assumption that they're not working. Its set to the default device and enabled, but how do I check if it was muted? They were working fine one day but after going out for a night I came back and it wasn't working. Not sure what I might have done. Any help?
