My metal isolation box shares ground with the computer. That way I can use normal audio jacks and cables. On the other side, I use a DB9 connector to isolate the box from any wires going to the radio. My PTT connection is isolated via an optoisolator (4N33), requiring another DB9 to the computer serial port for control. If you isolate the audio signals but not PTT, then you've again "un-isolated" everything. If you use VOX for PTT, this isn't an issue.
