Hi Alexandr! rtaudio seems to be a Windoze thing.
RTAudio is a proprietrary codec which can be licensed from Microsoft<http://en.wikipedia.org/wiki/Microsoft> . And Nicolas seems to experiment with a kind of Linux. The Fedora geeks told me that OSS on Linux is not really OSS, it is an ALSA emulation of OSS. What Nicolas needs is perhaps this: /dev/dsp1 This would be his USB sound card.
