This package has a number of issues.

It pulls git HEAD but sets pkgver=0.1.7. Either pin to the release tag, e.g, #tag=${pkgver}, or rename to python-rtmixer-git and do proper VCS versioning.

arch=(any) is wrong (build produces arch-specific artifacts via CFFI). Use real arches.

git and python-sounddevice dependencies are missing, and runtime deps are in the wrong place. Suggested:

depends=(python portaudio python-cffi python-pa-ringbuffer python-sounddevice)
makedepends=(git python-build python-installer python-setuptools python-wheel)

On 2026-01-10 Rosslaew's recommendation worked for me as well.

i got this error:

For a manual intervention I managed to install the package by adding this fix at the end of the prepare() step: sed -i "6a#include <stdbool.h>" src/rtmixer.c

@Stroopwafel: thank you for the explanation and the python-rtmixer-git package.

@T-vK: You could try to extract the portaudio source to the path where it is expected instead of modifying flags.

The reason it cannot find pa_ringbuffer.c is because portaudio is a submodule of the project. Submodules don't get included in the source code archive in Github.

The way I got around it is by changing the PKGBUILD to be essentially a -git package. Following the AUR guidelines, I've attached a pastebin https://pastebin.com/GPiWCzQT

I don't know how to compute the checksum, so (while it is generally a very bad idea) I installed using --skipchecksums
