Hi Praphan,

Thank you for your reply.

I also have a RME ASIO sound card in my pc. It has been deactivated since I start using the X-box. Maybe I should give it a try and put it back to work. Not an easy task; I had serious issues with the RME drivers.

Thanks anyway.

PauL.

I did a new install of XXHighend. Tried to select the AKDesign USB ASIO output device I need to drive my Playback Design dac. But the device is not on the list. How can I add this device to the output device list?
