IIRC there is some kind of console utility for GUS cards which capable to mute card's line-in. Like Inertia Player internal feature but standalone tiny program. Maybe it was special version of ultrinit.exe with additional key, maybe 3rd party program - can't remember.
Don't want unplug my Covox connected to GUS line-in and hosted on Iomega ZIP every time i use that drive otherwise i listen marvelous and very loud japanoise during disk access.
