Erm... perhaps you can clarify this to avoid confusion. Possibly you mean that PortAudio tries to open the ALSA hardware device directly but is not capable of providing the correct sample format. In which case "the Audio4DJ doesn't work correctly with PortAudio" would be more accurate? Because the Audio4DJ works fine with ALSA, including low latencies.

The actual sample format supported by the hardware is not an issue because, as intended by the ALSA design, a 'plug' will handle any conversion; eg. plughw:Audio4DJ,0,0 > Long story short, we are very close to solving the issue, and pretty > soon Audio4DJ (and probably the other NI cards) will be fully supported > on linux with native low-latency ALSA, no JACK required.
