2 years ago Right now PulseAudio isn't set up to work with pipewire. Related: #92. Some of the other errors might be separate issues. Do you still have alsa? Can you find an alsa.conf file? The invalid PaErrorCode message is a bit of a bug: we should be throwing a better error there.

2 years ago I have the pipewire-alsa compatiblity shim enabled and there are some related-looking files:
% ll /etc/alsa/conf.d
lrwxrwxrwx 48 root 18 Sep 12:09 49-pipewire-modules.conf -> /etc/static/alsa/conf.d/49-pipewire-modules.conf
lrwxrwxrwx 40 root 18 Sep 12:09 50-pipewire.conf -> /etc/static/alsa/conf.d/50-pipewire.conf
lrwxrwxrwx 48 root 18 Sep 12:09 99-pipewire-default.conf -> /etc/static/alsa/conf.d/99-pipewire-default.confWell one thing to try would be to add /etc/static/alsa/ to the list here:

2 years ago Another thing to try might be to build a newer version of PulseAudio in BinaryBuilder:
https://github.com/JuliaPackaging/Yggdrasil/blob/master/P/PulseAudio/build_tarballs.jl
But I suspect the best way to solve it would be to build Pipewire with binary builder and then make alsa-plugins aware of it:

1 year ago I tried setting the ALSA_CONFIG_DIR environment variable which got me past the build step but creating a stream failed. The error is coming from
https://files.portaudio.com/docs/v19-doxydocs/portaudio_8h.html#adc955dfab007624000695c48d4f876dc
which says
The user should first determine the available device ids by using the supplied application "pa_devs".
and then set the environment variable PA_RECOMMENDED_OUTPUT_DEVICE
so I look at pa_devs.c and it's calling Pa_GetDeviceCount. But
julia> PortAudio.LibPortAudio.Pa_GetDeviceCount()
0even after
julia> PortAudio.LibPortAudio.Pa_Initialize()
0
julia> PortAudio.LibPortAudio.Pa_GetDeviceCount()
0so something's wrong.
I didn't set ALSA_PLUGIN_DIR but I don't know if that's relevant.
In Python it works fine.

>>> import sounddevice as sd

I tried to follow the readme.
