Test file to reproduce the problem

Test like this:

- make sure ibus-typing-booster is installed to have the test .wav file used in the script available
- Run the script like this: `python3 pyaudio-test.py`

Thank you very much for the bug report and the PRs. I'll use the opportunity to include some additional changes (update spec to latest Python packaging guidelines, migrate to SPDX license).

pyaudio-test-trigger-hang.py

With the updated python3-pyaudio, it works but not reliably. It sometimes hangs, pretty often actually.

The attached script makes it rather easy to reproduce the hang. It should do 99 beeps, but does the full amount of beeps not always, quite often it hangs like this:

and here at this `ALSA lib pcm_dmix.c:999:(snd_pcm_dmix_open) unable to open slave` message it hangs, there is no more sound and the script never finishes.

I can stop it here with Control-C only because I added:

    # Make Control-C work when it hangs:
    signal.signal(signal.SIGINT, signal.SIG_DFL)

to the script.

When it hangs, stopping the script with Control-C and starting it again, usually reproduces the hang immediately.

Using

    aplay /usr/share/ibus-typing-booster/data/coin9.wav

in a different terminal while this test script is hanging does not work, aplay then hangs as well.

But after stopping the test script with Control-C, running

    aplay /usr/share/ibus-typing-booster/data/coin9.wav

once seems to "fix" the problem, aplay produces the correct sound and the next run of the test script usually works as well.

I should probably make a new bug report for this hang.

I can quite easily reproduce the hang using your latest build on Fedora 38: https://koji.fedoraproject.org/koji/buildinfo?buildID=2287903

I can reproduce similar issues (see below). Anyway, I suggest a new bug report as well. Let's keep using this one for the update and fixing the issue that the package didn't work at all.

Just to double-check: Do you see the same issues with your own local builds of pyaudio?

A few notes from my tests:
- works worse if there are other active audio players (e.g. a browser): lots of stutter, sometimes hanging pyaudio
- I tried using mpg123 with portaudio plugin (to test the underlying portaudio library): issues couldn't be reproduced
