This sound card supports asio mode. In your case, I estimate that nine times out of ten, the rack can't be opened and used normally at the same time, that is, the host software.

You have to open other rack software that has occupied the asio channel, and then au will not be loaded, and then it will be displayed that only MME mode can be used.

Solution: Close other related host software and reload asio mode.

Your sound card is supported when you close other software and can choose asio mode.
