update portaudio

[dansgithubuser]

Hey, hope it's not too forward to lead with a PR. Figured it's a tiny change so might as well clarify that part up front.

I was hitting PortAudio/portaudio#268 and noticed the portaudio people solved it somewhere in 2020, and made a release in 2021. I tried installing that version of portaudio, but need a static build. pgk_config has its own unsolved problem with static system libraries rust-lang/pkg-config-rs#102.

Not sure of a couple things:

• how married is this wrapper to 2014 portaudio?
• am I missing some other way to get what I need?

I can confirm this changed solved my issue. Not sure about anything but dead obvious regressions, though.

All the best,
Dan

• how married is this wrapper to 2014 portaudio?
  • Not sure... haven't followed portaudio development but if it works for you its probably fine.
• am I missing some other way to get what I need?
  • No, this is probably the way but... the Rust community has largely converged onto https://github.com/RustAudio/cpal for the same space that portaudio covers. Is there any reason you prefer portaudio over cpal?

Hey, thanks for the merge!

Yeah I've been keeping my eye on CPAL. I rely on small fixed frame size and find that CPAL does not guarantee a frame size, at least on ALSA.

Code: https://github.com/dansgithubuser/playground/blob/master/languages/rust/cpal/src/main.rs

Example run:

playground/languages/rust/cpal$ cargo run --release
   Compiling cpal v0.1.0 (/home/dan/Desktop/repos/playground/languages/rust/cpal)

Happy to write up an issue if it'd be useful. I just assumed it's one of many things CPAL is working through as it matures. Or just not considered an issue.
