Hello, The wave driver will allow you to use the 001 as your preffered playback device. The ASIO driver will allow you to use the 001 with other audio apps that support ASIO. However, you can not have both the ASIO driver and the Wave driver installed at the same time. This is a current limitation of the drivers. In your case I would remove the ASIO driver and install the Wave driver. The ASIO driver can be removed from Control Panel > Add/Remove Programs. You can download the Wave driver here: I hope this helps. Mike
