I just thought I'd update the list on my progress working with Dmitry, the Portaudio maintainer, on properly supporting the Audio4DJ sound card under linux. Right now the Audio4DJ doesn't work correctly with ALSA but works fine with JACK. It turns out the Audio4DJ has some strict requirements in terms of its audio input format: it requires 24 bit Big Endian samples, and nothing else will do.
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. I had the card at 2ms and it worked great. cheers, Owen Williams -------- Forwarded Message -------- > From: Dmitry Kostjuchenko <dmitry...@iauxsoft.com> > To: Owen Williams <owilli...@mixxx.org> > Subject: Re: Fw: Audio4DJ progress > Date: Sat, 11 Feb 2012 05:02:32 +0200 > > Hi Owen! > > Thank you very much for test.
