This isn't the case for me. It'll time out whether Edit is already on or not. Was just getting frustrated about this last night. It's happened regardless of the cable I'm using. Always plugged into the back of my Mac.
I've found no way of avoiding it. The only way I've found to fix it is to turn my AX8 off, then on again. That usually does it, but that means I have to turn off my power amp too in order to avoid the pop. Over all, it's just a big pain to have this happen at all, let alone so frequently.
Edit shows that I'm connected. But it times out the comm.
