A similar thing happens to blocking.rs, saw.rs, sine.rs, but not on devices.rs or hosts.rs.
I suspect that some struct passed to the C functions isn't correct.
Hmm this might have something to do with not having the linux ALSA extension header bindings set up yet. We only have bindings to the general portaudio.h so far. #22 is the related issue.
Would you mind running the devices.rs and hosts.rs examples and posting their output to here?
I only have OS X available to me at the moment, but I'm hoping to use rust-portaudio w/ ALSA for some embedded audio stuff mid-next month which is when I was planning on having a go at this. It shouldn't be too tricky to run rust-bindgen on the necessary header and set it up (I'm happy for someone else to beat me to it).
I can't get into the computer on which I've initially done that, but on another computer, also running Ubuntu 14.04, but running Pulseaudio, I get the same error and I get:

fyi, i was seeing this with debian bullseye as well, however, it seems to be resolved with portaudio 19.6.0-1.1
