I have sort of the reverse problem. I hope it is close enough to the subject matter of this thread to be welcomed here instead of needing its own new topic. (I'm new to this forum.) I'm searching for a way to tell my HD500 to NOT hijack the computer audio output when the USB is plugged in. I plug in the USB only to run the HD500 Edit interface, not to capture audio. I want my computer audio to stay on the earphone output and go into my PA mixer into its own channel where I can EQ it to sound nice for YouTube videos, etc. to play my guitar along with. (not for recording) I don't want the computer sound to go through the HD and come out on my PA's guitar channel, which is EQed for my guitar. Is there a way to do this?
Also, I have the problem that hurghanico mentions where I plug in the USB just to run Edit, and whatever audio is playing (YouTube, etc.) freezes and has to be restarted. SongSurgeon, unfortunately, freezes and will not restart again properly at all unless I do some fiddling that I can't quite remember. I think I have to turn off the HD itself, leave the USB in, start SS, then turn on the POD again. Or some stupid ritual like this that I will have to figure out again next time it happens. Things would be much better if I could just tell the HD to keeps its hands off the computer audio output altogether, and connect only to the Edit program. Thanks in advance for any advise.
