silencing portaudio warnings #64
Comments

This is portaudio, the C library we use in PySoundCard. You are using a version of portaudio with debugging output enabled. You can fix this by using a version of portaudio without debugging output. Debugging output is a compile-time option of portaudio. There are other compile-time options, including support for ASIO and other Windows audio APIs. Is this the version from our installer? |

Yeah, I thought that might be the case. I'm on ubuntu and using the packaged version from software centre but I guess I'll have to compile it myself [sigh]. Actually I want ASIO support too for the card I have so it's probably worth it. cheers |

ASIO is Windows-only. I think that I packaged a version without debugging output and with ASIO in the Windows installers. I'm not 100% sure though. On Ubuntu, you should have the choice between OSS, ALSA, and JACK. |

Thanks for the info Bastian, I'll check your versions of portaudio.dll Jon Peirce |
Hi there, I'm looking at PySoundCard/File for use in PsychoPy as a cross-platform way to load and play sounds quickly (not necessarily with lots of high-level features). I'm currently testing on linux and things look pretty good so far (it was easy to install, load and start playing!)
I'm getting a load of warnings though as the pysoundcard package loads. I suspect they're coming from portaudio and it looks like they're due to devices/channels not loading correctly. Doesn't have any effect that I can see on using the default_output_device though. I wonder if they can be silenced, or whether this is some flag set at compile time in libportaudio?
They'll be pretty annoying if I see that every time I run a script!
