Failing to start under Pipewire #121
Comments
|
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. |

I have the pipewire-alsa compatiblity shim enabled and there are some related-looking files: |

Well one thing to try would be to add Line 137 in 06c6fd0 |
|
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: https://github.com/JuliaPackaging/Yggdrasil/blob/master/A/alsa_plugins/build_tarballs.jl |

I tried setting the https://files.portaudio.com/docs/v19-doxydocs/portaudio_8h.html#adc955dfab007624000695c48d4f876dc which says
and then set the environment variable so I look at 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 In Python it works fine. https://github.com/spatialaudio/python-sounddevice/blob/master/sounddevice.py#L453 >>> import sounddevice as sd
>>> sd._lib.Pa_GetDeviceCount()
13julia> ENV["ALSA_CONFIG_DIR"] = "/etc/static/alsa"
pkg> add PortAudio, SampledSignals
julia> using PortAudio, SampledSignals;
julia> stream = PortAudioStream(2, 2; warn_xruns = false);

I tried to follow the readme.
NixOS, with Pipewire emulating Pulseaudio.
Julia 1.7.1
