Loud continuous beeping With Garageband and my MIXER.
I Just got a Peavey PV 8 USB Mixer with 2 MXL 990 Phantom powered condenser mics.
Every time I connect my Mixer and open garage band there's a long continuous beep in the backround. No matter what I do I cannot drown it out. I've disabled the Audio MIDI Set up. I've gone into my preferences and disabled the internal mic and speakers and still nothing. The strange thing is that the mixer is fine if I have GarageBand shut down. But as soon as it even gets to the new project window The beeping starts again. Someone please help me.
