	Hi Ken, you need to enable those in your SConstruct file ( turn those 0s into 1s ). I compile with all of them on, portaudio, alsa, and jack. Then you should be able to use it. If you don't need to be running anything else at the same time, alsa is the best. Running with --expression-opt --sched and -+rtaudio=alsa I can get very low latency and rock solid stability as long as I make sure my cpu use doesn't spike up into the 90's. Running at 70-80% cpu use it is very stable.

	And yes, as mentioned you do need portaudio v19 for portaudio output. But if that is a problem, you may be able to compile fine with only the alsa option enabled in SConstruct.
