Sample rate switching a problem in WDM drivers only. Other have problems with pops clicks etc.using ASIO.
I have a problem with a company not doing what they promise. Happened with multiple units using zero monitoring and now( apparently) with official Windows 10 drivers. Maybe with El Capitan drivers now.
I have never encountered a company that would just refuse to communicate with the owners of their products. It as if any communication with Mr816 in it just goes into some sort of spam folder.
