Hello, hope someone can help...

I am using os 10.4.5 and i would like to enable the play thru option in the Audio Midi Setup utility.

I am using Griffin iMic (the new one) and in the Audio in section on the master and 1&2, thru and mute is greyed out...

is there a way of enabling this?

I have the Line In application from Rogue Amoeba which does this, but would like to use the audio midi setup.

thanks for your time

regards

Lee
