OSError: [Errno -9986] Internal PortAudio error

[fabihoern]

Hi,

I'm programming with PortAudio / PyAudio. I installed the library with homebrew. On my windows Pc I never got this error.
Desktop

• OS: Mac OS
• OS Version: Big Sur 11.1
• PortAudio version: latest
• PyCharm

Simple sr code:
import speech_recognition as sr

r = sr.Recognizer()
mic = sr.Microphone()
with mic as source:
r.adjust_for_ambient_noise(source)
audio = r.listen(source)
transcript = r.recognize_google(audio)
print(transcript)

I always got this error:

||PaMacCore (AUHAL)|| Error on line 1277: err='-66748', msg=Unknown Error
Traceback (most recent call last):
File "/Users/fabianhoernlein/Desktop/testsr/main.py", line 6, in
with mic as so
File "/Users/fabianhoernlein/Desktop/testsr/venv/lib/python3.9/site-packages/speech_recognition/init.py", line 138, in enter
self.audio.open(
File "/Users/fabianhoernlein/Desktop/testsr/venv/lib/python3.9/site-packages/pyaudio.py", line 750, in open
stream = Stream(self, *args, **kwargs)
File "/Users/fabianhoernlein/Desktop/testsr/venv/lib/python3.9/site-packages/pyaudio.py", line 441, in init
self._stream = pa.open(**arguments)
OSError: [Errno -9986] Internal PortAudio error

Process finished with exit code 1

I tryed a lot around packages, reinstall, update, ...
thx for help,
Fabi

HI,
I have a similar Issue on

• Machine: Macbook Air Early 2015
• OS Version: Big Sur 11.1
• PortAudio version: 19.6.0

sounddevice.PortAudioError: Error opening InputStream: Internal PortAudio error [PaErrorCode -9986]

I tried to run guest Ubuntu VM under VirtualBox with passing input audio to it and works as expected there so it is something specific for MacOS.

Please take a look as probably ppl have a similar problem

Test snippet:
import sounddevice as sd
from scipy.io.wavfile import write

fs = 44100 # Sample rate
seconds = 3 # Duration of recording
myrecording = sd.rec(int(seconds * fs), samplerate=fs, channels=2)
sd.wait() # Wait until recording is finished
write('output.wav', fs, myrecording) # Save as WAV file

//Arek

I believe also this is a duplicated issue as #395 looks the same

[philburk]

Yes, this is a DUP of #395
A fix is pending in #356

Actually based on comments from other connected issues:
brew uninstall portaudio && brew install portaudio --HEAD worked for me as WA so it looks like needed changes are already there
