Ahhh!!!! Don't do this! Your pulling 5V off the port and then pumping it
into the output RCA jack. You were lucky you only got hum and not a bang!

Use a short 1/8 jack to RCA and many of your problems will go away.


PS. I use a Large capsule mic through a seperate power supply, a pop filter
and a mic pre amp all before it gts near my mac.
