The issue is not related to WSL. Please report any on-topic issues.

The portaudio.h file is provided by portaudio19-dev package. The file list of that package can be found here https://packages.ubuntu.com/jammy/amd64/portaudio19-dev/filelist.

[EdSeymore]

It is my understanding that portaudio is provied by standard Ubuntu package and that WSL supplies a non standerd Ubuntu for the WSL support. The files referenced are not present in my Ubuntu 22.04 image under WSL2 with Windows 11.

[Biswa96]

The portaudio19-dev has to be installed to get that portaudio.h file.

@EdSeymore you need to add the portaudio19-dev package. This package contains the development files and not installed by default. apt install portaudio19-dev should take care of it.

Thanks. Now Successfully installed PyAudio-0.2.13.

Now I am getting a stream of messages from ALSA lib:

This may not be an WSL2 problem; but, I am trying really hard to use WSL2 with Ubuntu in place of a separate Ubuntu system and the complexity of the Operating Systems is making this really difficult.

End users should not have this much trouble setting up a working environment to run python applications. Trying to debug configuration problems with web search has not been productive for me.

I really have no idea how Windows and Ubuntu share devices on a single system and very little desire to know. I just would like for supportted systems to actually work when installed.

WSL2 just happens to be a key component.

Has anyone gotten PyAudio to work on Ubuntu 22.04 with Windows 11 and WSL2 without the ALSA lib messages?

Suggestions would be appreciated.

The python3 code to illistrate this conditions is as follows:

!/usr/bin/env python3

-- coding: utf-8 --

import pyaudio import wave import sys CHUNK = 1024 file_path = "audio.wav" wf = wave.open(file_path, 'rb') # Modified ets 01/31/2023 t_audio =wf.getnframes() / wf.getframerate() p = pyaudio.PyAudio() stream = p.open(format=p.get_format_from_width(wf.getsampwidth()), channels=wf.getnchannels(), rate=wf.getframerate(), output=True) while len(data := wf.readframes(CHUNK)): stream.write(data) stream.close() p.terminate() wf.close()

I am having the same issue. Has there been any update regarding this please?

At the time being, has anyone succeeded to have pyaudio working in WSL2?
