ASIO tries to be a "one man dog" in order to deliver that lower latency figure and often is the case where we can't open two audio programs that are set to use the same sound device's ASIO drivers at the same time. This might be your problem.

Try setting BiaB to MME sound drivers, which will really invoke the WDM Windows Sound on any modern OS.

Set Amplitube to use the ASIO drivers as that is the program where the low latency figure is needed for realtime playing.


Good luck,
