Does not work on mac

On mac with python 3.9.9:

Pyo warning: Portaudio input device `MacBook Pro Microphone` has fewer channels (1) than requested (2).
||PaMacCore (AUHAL)|| Error on line 1301: err='-66748', msg=Unknown Error
Portaudio error in Pa_OpenStream: Internal PortAudio error
Pyo error: From portaudio, Internal PortAudio error

Hi,

Try with:

Server(ichnls=1)

[Fraer]

thank you! looks like portaudio was also missing, so i've installed it:

brew install portaudio --HEAD

I'm running the following code:

from pyo import *
pyoServer = Server(ichnls=1).boot()
pyoServer.start()
sf = SfPlayer("/Users/toto/Downloads/sound.wav", speed=2, loop=False).out()
print("ok")

i hear the sound, it's fine but the print("ok") statement is not executed and the following log appears:

||PaMacCore (AUHAL)|| Error on line 2500: err='-50', msg=Unknown Error
||PaMacCore (AUHAL)|| Error on line 2500: err='-50', msg=Unknown Error

I'm getting similar errors. Intel Mac, macOS Monterey, Python 3.8.9.

Using Python 3.9, here's a similar error:

In [3]: s = pyo.Server(ichnls=1).boot()
||PaMacCore (AUHAL)|| Error on line 1301: err='-66748', msg=Unknown Error

Pyo error:

It looks like there's a related discussion here, unresolved as of today.

I was able to move forward with the most recent posts there, by doing this:

>>> import pyo as p
>>> s = p.Server(audio="coreaudio")
>>> s.boot()
>>> s.start()
>>> sf = p.SfPlayer("sound.aif").out()

Same problem here macOS 12.6 (21G115)

This does not run and corrupts CoreAudio. I can't play any song after running this script and must reset sudo killall coreaudiod to get it to go back to normal

s = pyo.Server(audio="coreaudio").boot()
s.start()
a = pyo.Sine(mul=0.01).out()
