FreeFull tried out the portaudio example today and was getting an overflow error. Here's his full output:

Successfully terminated PortAudio.

Perhaps there is still some work we need to do to get things running smoothly on Linux?

[mitchmindtree]

He has multiple other software that uses PortAudio as a backend, so it must be something to do with our bindings.

[mitchmindtree]

This should be fixed by #77, #78 and #81. Will reopen this if anyone else reports further issues.

Unfortunately, now behaviour is even worse. The blocking example terminates after just one read with fish: Job 1, “./blocking ” terminated by signal SIGSEGV (Address boundary error) and the non-blocking example floods the console with underrun messages.
