I've put a linuxppc version of pd-032 up at http://mambo.peabody.jhu.edu/~karlmac/download for anyone who is interested. It is fairly well tested but not garuntees. Most likely you will have to specify -frags n to get it to work with the built-in sound. Hopefully I will get alsa to work on my G4 soon so that I can test full duplex (the only extra card I have is only full duplex with alsa). Is anyone else using linuxppc?
