I've got the latest drivers installed,
rebooted the Mac as required, and I used Mac preferences to set the audio for the laptop to the m20d choice.
I can see audio coming in to the Mac, but when I play iTunes, nothing seems to come back out from the Mac to the m20d.
I see in the FAQ it tells me I need to add a laptop icon to the stage, and then set levels, but I can't find one that accepts USB.
I have used up the analog audio inputs, and when I try to drag the laptop icon to the stage it tells me
"No jacks are available that can accommodate this icon."
I need a laptop icon with a USB input, but the only one I find has a stereo jack picture attached.
Also, when recording into Logic, I can see the audio in, but at a very low level.
Line6 m20d driver 1.23
m20d firmware 1.2
