OK, copying and renaming portaudio_x86.dll in ReleaseMinDependency first and it seemed to work:

Those don't seem to support WDM-KS, and your error was there ...
Could you please try those: https://github.com/adfernandes/precompiled-portaudio-windows?
I don't want to disable WDM-KS in the pre-packaged DLLs, because on some (most?) systems it works fine and as I understand it's one of the more professional (i.e. low latency) backends.

@Maneesh3 Please note that the link you are recommending points to an older PortAudio version.
It would probably better to recommend Christoph Gohlke's DLLs instead: http://www.lfd.uci.edu/~gohlke/pythonlibs/#sounddevice
Those are also easier to install by simply using pip. The previous installation can be uninstalled with pip uninstall sounddevice.

Hmmm, I have no idea what's going wrong here ... but that may be because I have no clue about Windows and its sound architectures at all.
I've just tried it on Windows 7 64bit and I didn't experience the crash:
C:\Users\ilovewindows>python
Python 3.3.2 |Continuum Analytics, Inc.| (default, May 17 2013, 11:32:27) [MSC v

Type "help", "copyright", "credits" or "license" for more information.
>>> import sounddevice

Does anyone else get the assertion error?

Realised I should have specified that this is Win10 .. it should be sufficient to try in one of the trial win VMs that ms provide for testing, like those on dev.modern.ie.

Doh - silly me - I am on python 2.7.10 - you are testing 3.3.2

commented on July 28, 2024
I didn't think that the Python version matters, because the error is directly in the PortAudio library.
.. it should be sufficient to try in one of the trial win VMs that ms provide for testing, like those on dev.modern.ie
Thanks for the hint, I didn't know they offer such images, that's quite useful.
However, I don't get my audio device recognized in the virtual machine (using VirtualBox, where I did activate the audio device), it always just shows "No audio devices are installed".
Importing sounddevice works without error, but of course there are no devices available ...
Any idea how I could get the audio device working?
Anyway, if somebody wants to get into this, here's the code with the assert() in question:
static const KSTOPOLOGY_CONNECTION* FindStartConnectionFrom(ULONG startPin, PaWinWdmFilter* filter)
{
unsigned i;
const KSTOPOLOGY_CONNECTION* connections = (const KSTOPOLOGY_CONNECTION*)(filter->connections + 1);
PA_DEBUG(("FindStartConnectionFrom: Checking %u connections...", filter->connections->Count));
for (i = 0; i < filter->connections->Count; ++i)
{
const KSTOPOLOGY_CONNECTION* pConn = connections + i;
if (pConn->ToNode == KSFILTER_NODE && pConn->ToNodePin == startPin)
{
return pConn;
}
}
assert(FALSE);
return 0;
}For the full code have a look at https://www.assembla.com/spaces/portaudio/subversion/source/HEAD/portaudio/trunk/src/hostapi/wdmks/pa_win_wdmks.c (but note that the pre-packaged DLL uses older code http://www.portaudio.com/archives/pa_stable_v19_20140130.tgz).

OK, I got it to work, I just changed the "Audio Controller" in the VirtualBox settings from the default "ICH AC97" to "Intel HD Audio".

I tried only playback (because I currently don't have a mic connected) and it works for MME, DirectSound, WASAPI and WDM-KS.
I even installed ASIO4ALL, which plays a strangely distorted sound, so there seems to be another issue ...

Ah, I'm using VMWare - (sound in vbox was wrong in Ableton)..
Yeah - I also had weird sound with Asio4All in vbox - it was playing everything 1/2 speed !

I just tried it on Windows 7 on a real laptop with a real soundcard and a real ASIO driver, where it sounds perfectly fine.
So I guess this is an issue with ASIO4ALL and/or virtualization.
But back to your original problem ...
Do other PortAudio applications (e.g. Audacity) work on your (virtual?) setup?
Since this happens during initialization, I suspect that it's a general problem with PortAudio, there isn't really anything much done in Python at this point ...
You could probably try writing a minimal PortAudio application in C and switch on all debugging features to see what's the problem.

Audacity (2.1.1 - 32 bit - installed from chocolatey) seems to open and play an mp3 using
the 3 backends - WASAP, Directsound and MMI
I can't find a portaudio dll in audacity, otherwise I'd try swapping it in + see what happens.
So - on python 3.5.0 32 bit (I switched in the meantime).. .I tried swapping in the dll from here
https://code.google.com/p/portaudiosharp/downloads/detail?name=PortAudio.dll
and it doesn't crash when I import sounddevice now..

Trying the version in 'Release' didn't work - do I need more than just the dll ?

I think "ReleaseMinDependency" is the recommended version, the others might need additional libraries.
Does WDM-KS work in the first case?
I can't really see that in all the debug output ...
from python-sounddevice.
stuaxo
commented on July 28, 2024
Ah, I have no idea if it WDM-KS works on that or not - it seems to have something about WDM, but not WDM-KS..
It didn't crash python on importing sounddevice, which is the most important thing to me. I'll see if I can try some examples that actually do something.

mgeier
commented on July 28, 2024
Check out print_devices(), this lists the devices together with their host APIs.
You can also get the same thing with
python -m sounddevice
If WDM-KS is supported, it would be interesting if/how I could change my DLLs in a way that they will work, too.

Yup - the title would seem to be accurate now - Windows 10 in VMWare Player (the free one) is the only windows I have right now..

TBH, I'd convert back to vbox if the sound wasn't so borked in there - it's only so I can try ableton lite with a gizmo I bought... apart from the sound working, it doesn't work super well and slows down my computer :/

OK, thanks, so it seems to work.
If you can live with switching to a different DLL, I guess it's fine for this special case.
If you have (or anyone out there has) an idea what I could do the make my DLLs work, too, speak up!

stuaxo
commented on July 28, 2024
Maybe we can start to narrow the differences. Is there any chance of compiling the same version he has ?
First thing is the version, is there any chance of compiling the version he has (r1891) ?
I know with python modules mixing VS compiled and MingW compiled modules doesn't work, but don't see how it would apply to a DLL on CFFI.

from python-sounddevice.
mgeier
commented on July 28, 2024
Thanks for the info. There seem to be several slightly different issues with Windows 10 (and some specific drivers), I think the one where they talk about an error at initialization might be the same we have here. I didn't see a solution there, though.
I'm cross-compiling the DLLs with MXE which have their own settings for PortAudio: https://github.com/mxe/mxe/blob/master/src/portaudio.mk.
The problem is that there was no new official release since the one MXE is already using (see http://www.portaudio.com/download.html). The only newer "release" in http://www.portaudio.com/archives/ is pa_snapshot.tgz.
Just for testing purposes, I compiled DLLs for this latest snapshot in the "portaudio-snapshot" branch:
spatialaudio/portaudio-binaries@51c4331
If you want, you can try these on your setup.
But even if this works, I don't think it's a good idea to release DLLs that don't have any version information on them.
Sadly, the PortAudio people make releases very scarcely.
from python-sounddevice.
stuaxo
commented on July 28, 2024
I tried the 64 bit one and it still crashes (which is reassuring in a way).
I downloaded MXE, and also made a git copy of the port audio svn. I guess if I can build an earlier version and not crash it should be possible to bisect +find the commit that caused it.
from python-sounddevice.
mgeier
commented on July 28, 2024
Ah, I didn't know that r1891 was older than 20140130 ...
Yes, you might be lucky and find a change in PortAudio that caused the error, but it might as well be a bug/incompatibility in the Windows stuff implemented in MinGW64.
I have the feeling that the latter is more likely ...
Either way, good luck!

@stuaxo Thanks for the update!
I still don't know what's going wrong here, but since not so long ago, there is a new version of the PortAudio DLLs available from Christoph Gohlke: http://www.lfd.uci.edu/~gohlke/pythonlibs/#sounddevice
Those would probably be worth a try!

I was using Jupyter Notebook in Anaconda (python 3.8.5) on Win 10 64 bit. I had exactly the same error after I ran '!pip install sounddevice' in an .ipynb file. I fixed it by:
- Shut down jupyter notebook and open anaconda prompt (anaconda3)
- Run 'pip uninstall sounddevice' (until it successfully uninstalled)
- Run 'conda install -c conda-forge python-sounddevice' (until it successfully install)
- Open jupyter notebook again. Run 'import sounddevice' and it FINALLY works perfectly!!!
Might not be exactly the same environment but hope my solution can help!
