New Mac OS compatibilty?

Arjan P I changed the (Source Invert per 8) the input to SLOT1-1 through SLOT1-16 per your suggesting and still no sound. This has to be something minor and most likely in my face but I can't find it for the life of me. As I said before no hardware changes were made and all I did was reinstalled my OS to clear the anomalies I was having. Ugh this is getting real frustrating. Meters are moving in the software but something is blocking it from coming into the DM and out to the speakers

I am not familiar with the workings of the driver in Windows, but after a fresh/first install on the Mac I have to manually switch on the 'second stream' in the firewire card, which makes channels 9-16 available to the computer. I am not at home at the moment, but could make a screenshot tonight or tomorrow morning European time.
Is there such an option in the settings for the driver in your computer?

I'm unaware of that option but when I get off from work I will be trying again and advise
