Sorry I'm not sure how to fix that, it's an error with ALSA, which I only interact with indirectly through pyaudio. Does sound work otherwise on your laptop?

[Berend Kapelle]

I have the same issue, running with Ubuntu 13.04 on a Lenovo T430s Laptop. Otherwise Sounds works perfectly.

I installed pyaudio via the .deb package. pip install pyaudio failed

I have the same problem, running Ubuntu 13.10

Actually, it's working despite the "error" message.

Same problem... Did anyone happen to get it running?
