This solution works very nicely (although it takes a little time). > > Good luck, > > Eric Klein > eklein@ait.nrl.navy.mil > > I have a camcorder cable, that has one 4-pole mini-jack connected to 3 mono RCA plugs, but the connections are all wrong. i.e. the ground or sheild on the RCA plugs is not connected to the Ground pole of the mini jack as far as the Audigy LS sound card is concerned. It is only correct for use with a camcorder. This is all quite annoying, because a simple mono jack to RCA plug does perfectly for SPDIF out to Coax input on the Audigy 2. But this does not work with the Audigy LS. So, I will probably have to go with option (1).
