1 year ago Hi, hope someone can give me some hints to debug the problem.
The problem has a minimum working example that is simple as that: open a terminal and call python3, then in the python commandline just type: import sounddevice
The python commandline will NEVER return, so you are stuck.
I also removed the video card, just in case the hdmi out create problems, but nothing improved.

1 year ago Wow, that sounds mysterious!
I don't really have a clue what could go wrong there, but there is one thing you could try: you could disable the call to _initialize():
This should at least let you import sounddevice as sd.
After that, you can manually call sd._lib.Pa_Initialize() and see if that works.
If that works, the problem has likely to do with the redirection of stderr output, which is done in _initialize().
If not, I guess that's a problem with the underlying PortAudio library.
This issue may or may not be related: #90.

1 year ago Hi, I only had now the chance to try it.
Commenting the Initialize() solves the crash. This is what happens when I later do the Initialize manually:

0Thanks for the update!
According to your output, Pa_Initialize() is successful.
The many error messages are expected, and are the reason why I'm trying to redirect stderr.
So the problem indeed seems to be caused by the redirection. Can you please try the minimal reproducing example from https://github.com/spatialaudio/python-sounddevice/issues/90#issuecomment-1182709958?

1 year ago Yes, the fix works! I followed your commits in #444 I assume that the problem is already fixed if instead of installing with pip, one clones sounddevice from the github repo, right?

No, it's not yet merged into this repo, because it hasn't been tested on Windows yet. But you should be able to install it with something like:
python3 -m pip install git+https://github.com/mgeier/python-sounddevice@redirect-with-dup2Uhm, is the branch redirect-with-dup2 correct? I installed that but still get the kernel fault.

1 year ago Here's a bit more detail with respect to my previous comment.
On the same machine where I had previously fixed the issue with success I reinstalled Ubuntu, this time the 2022 LTS instead of the 2020 one. I installed the redirect-with-dup2 branch for sounddevice and I stumbled in the same issue.
I have reviewed the code, made some changes and I see that the kernel fault is triggered by Pa_initialize:
_check(_lib.Pa_Initialize(), 'Error initializing PortAudio')
I will revert to Ubuntu 2020 LTS and see if things get solved...

If Pa_Initialize() makes problems, there isn't much I can do on the Python side, this would have to be reported to the PortAudio project.
But it seems that os.dup() and os.dup2() are working, that's good to know.
Hi all, I've been using a small GUI application written in python 3 and kivy that uses sounddevice to record and analyze audio.
This works well on my Linux mint 19 machine. Now I am launching the application on a fresh Ubuntu 20 install on a NUC and I have the following problem: on application launch I see a black GUI, nothing happens, the application can't be killed (not even with kill -9 from command line). I have started debugging the application from PyCharm and it seems that the program is locked on import sounddevice. After that line the debugger loses control and can't even kill the application. Maybe sounddevice got the wrong audio card and gets lost? I don't know...
I've got Ubuntu 20.04.4 on a NUC 9i9 with: Card: sof-hda-dsp Chip: Realtek ALC256 and a graphic card: product: TU117 [GeForce GTX 1650] [10DE:1F82] which is also seen as audio device (through HDMI) and also Chip: Nvidia GPU 94 HDMI/DP
Currently I have the nuveau drivers installed but the official nvidia drivers behave the same. What can be wrong?!
