MacOS BigSur: ||PaMacCore (AUHAL)|| Error on line 1316: err='-66748', msg=Unknown Error

[sharonlev]

When attempting to run sample code from (https://python-sounddevice.readthedocs.io/en/0.3.7/_downloads/play_file.py) on a macOS Big Sur (clean venv based on py3.7), I am getting the following:

||PaMacCore (AUHAL)|| Error on line 1316: err='-66748', msg=Unknown Error
PortAudioError: Error opening OutputStream: Internal PortAudio error [PaErrorCode -9986]

any idea what needs to be re-build to support the new OS?

[mgeier]

Sorry, I have no idea what causes this error and how it could be fixed, but for the record, the same problem seems to appear when using PyAudio (which uses the same underlying library PortAudio), see https://stackoverflow.com/questions/65432130/pyaudio-oserror-errno-9986-internal-portaudio-error.

You should probably report this issue to the PortAudio project, see http://portaudio.com/contacts.html.

Maybe related:

• Can't open stream on macOS 11.x PortAudio/portaudio#395
• CoreAudio add support for new HAL API for applications that target Mac OS X >= 10.5 PortAudio/portaudio#356

Hi, I tried to reinstall and it's working now.
brew uninstall portaudio
brew install portaudio --HEAD

[sharonlev]

Thanks for the HEADs up ;)

brew install portaudio --HEAD

Looks like that did the trick here (regular install did not resolve yet)

[mgeier]

See also PortAudio/portaudio#468 and PortAudio/portaudio#470.

This hopefully goes away once the new version of the .dylib is used, see also #333.

[mgeier]

I've just created a new .dylib in case somebody wants to test it: spatialaudio/portaudio-binaries#8.

[mgeier]

If anyone still has this problem (especially on an M1 Mac), can you please try the .dylib from spatialaudio/portaudio-binaries#10 and report if it works?

[vrslev]

@mgeier I have M1 Mac and everything works fine without your custom built. I use PortAudio from brew (ARM version).

I am getting this on my Mac M1:

||PaMacCore (AUHAL)|| AUHAL component not found.

I have used home-brew to reinstall, but am not using head ATM

Can someone help me with this? I'm installing portaudio with conda. I don't really know how packages are published in brew or conda. Is there a nightly conda package that I could try to use, similar to that --HEAD command for brew?

[mgeier]

@stefansjs and @onehundredfeet

You can try to uninstall portaudio with conda and brew and then install sounddevice with pip.

I'm currently updating the installation docs here: #495.

Is there a nightly conda package

No.

If you really want to try the latest development version (which I think you don't need to solve the problem at hand), you can install it with pip as well: https://python-sounddevice.readthedocs.io/en/0.4.6/CONTRIBUTING.html#development-installation

However, the PortAudio packages from conda and brew will interfere with that just a badly.
