If you also have a Digidesign card in your PC, you can use your 192 via the Digidesign ASIO driver. 8 channels only, apparently.
The Digidesign ASIO Driver provides the following numbers of input and output channels:
Up to 8 channels of input and output with Pro Tools|HD systems
The ASIO Driver is not multi-client. Only one application at a time can use the ASIO Driver. Be sure to disable the Windows system sounds. It is also recommended that you use a separate sound card for games or other general work.
