I am currently having the following problem with Csound5. Trying to output Toot1 with the command csound -+rtaudio=alsa -o dac:hw:0,0 gives me this error: *** error: unknown rtaudio module: 'alsa' Failed to initialise real time audio output If I want to render to disk, there's no problem. I had no problems building Csound5. In the terminal as it built, I read that it included portaudio and alsa. My PortAudio is pa_snapshot_v19.tar. bin/patest_sine worked fine. Alsaplayer works fine. I've edited csoundrc as Istan Varga described Fri, 04 Mar 2005: To enable use of the ALSA plugin, add this line to $HOME/.csoundrc: -+rtaudio=alsa My Csound5 is from csound5-2005-08-27.zip. My alsa is 1.0.9b. My kernel is 2.6.12-gentoo-r6. Am I making some other mistake? I'm not sure myself how to further troubleshoot this. I've read in the csound-devel archive that others (Steven Yi) got this to work. How do I get it to work? Renick -- Renick Bell http://www.the3rd2nd.com -- Send bugs reports to this list.
