Is Wasapi in Audirvana event or push driven?

I want to upgrade my DAC, the Audio-gd R8, with the all new Anamero USB card. It seems it only works properly when the source is Wasapi event driven.

Hi Nemo,

i my experience the Amanero USB has its own driver, which requires ASIO:
download Combo384 Driver 1.067 for Windows 10 - Windows 8 - Windows 7

You are right, but the DAC accepts only Wasapi. I just contacted the dealer of the DAC. He told me that with the upgrade the firmware also will be renewed. With the new firmware Asio will be possible.
