I see that you are using ASIOAll. I would use the 18i20 native ASIO drivers. ASIOALL is just a MME/WDM wrapper that sometimes works with some audio interfaces while native drivers are make specifically for your interface. They are generally faster and less problematic.

There also may be a rate problem but I don't know for sure as I do not use ASIOALL. But one screen says 41KHz while another says 48KHz.

I hope this helps.
