sounddevice blocks input() about python-sounddevice HOT 6 CLOSED

Thanks for the report!

I can reproduce this with macOS and Linux.
I hope I can find a way to make this work but to still ignore the annoying PortAudio outputs.
I guess I'll have to undo the redirection after _initialize() ... or move the whole redirection thing into _initialize() ...

In the meantime, you can just remove the line _ignore_stderr() (very close to the end of sounddevice.py) as a work-around.

This is quite strange, since the input() prompt is supposed to be shown on "standard output" instead of "standard error". I've asked about this at http://stackoverflow.com/q/41394554/.

Wow, this is surprisingly complicated!

It turns out that my stackoverflow question is a duplicate of http://stackoverflow.com/q/14009714/.

And the whole thing seems to be somewhat of a bug in Python, at least it's not quite clear what the desired behavior should be. This might or might not be changed in a future Python version, there's an open issue: http://bugs.python.org/issue1927.

Since the current situation is so complicated, I don't really know what the proper solution for the sounddevice module should be.

Any suggestions?

For now, there is another work-around: just import the built-in readline module!

This should work as expected:

import readline
import sounddevice as sd
name = input("Enter your name: ")
print ("your name is " + name)

The order of imports doesn't seem to matter.

Thanks for investigating! That is indeed more complicated than I expected. The readline workaround fixes the issue for me, but if I have any thoughts on how to solve this for sounddevice I'll let you know.

I may have a clue to this old issue. Seems that an sd.InputStream will stop calling callback if you hit the enter key. I will raise with code as another issue.

This is fixed in the newest release.
