MBPr does not recognize Samson USB microphone.
I've been using a Samson GoMic USB for several months. Just today the MBPr has stopped responding to it. I can see the mic under <Sound>, I can select it as the input device, but it does not register any sound input. Works fine on two other macs. Build 12D78, osX 10.8.3 Any tips?
Thanks
