I’m new here. I’m trying to set up an HC 4500 to run with OTS AV. I’m having all manner of problems trying to get two stereo outs working. I’ve tried it on two separate laptops with two versions of ASIO drivers - The latest and the one before and so far nothing has worked. I have a feeling that it might help if I update the firmware, but on both laptops (vista and windows 10) the updater programme tells me the “file is not ready” and half the time tells me that the unit is not connected. This is of course not true. Can anyone else out there help?
