Ah ok, yes it is too expensive in my opinion also.
yes the 2.15 driver is activated, but I do not désinstaler the old driver: /
I had try to go through ASIO, WASAPI and other, increase the buffer, but always sizzling.
I plug therefore hiface 2 on a USB 2 port but it is placed on the wrong side of my DAC, therefore the cable goes around the laptop, but it is not too serious :)
By cons they should not say that hiface 2 is compatible with USB 3: D
Actually, I was not aware that they say Hiface 2 is compatible with usb 3? I thought they specifically said it was not. Anyway, many have found that it will not work properly with usb 3 ports, but it may be dependent on the specific motherboard. On my computer I can't get anything out of the usb 3 ports with the Hiface 2. So I just use a usb 2 port and it works perfectly.
