I recompiled with JUCE_AUDIO=1 in juce_config.h and was able to get far. The deviceSelector allowed me to select my Line6 UX2 device, but the moment I do that, I see an exception in audioDeviceIOCallback because inputChannelData[0] is null. This only happens if I scroll down to select the ASIO device.
Jules, is it possible to add example code that reads from ASIO? And preferably that mixes with a wav player?
