Re: [pygame] Noob question: playing sounds

[Michael Lutinsky]

I can verify that running:

$ python /usr/lib/python2.7/dist-packages/pygame/examples/sound.py

plays without error on my Kubuntu distro (x86_64 Linux kernel 3.19.0-18, 
pulseaudio 6.0). Must be a RPi issue?

I think you'll have more luck asking in the RPi forums.
Looking at the last post in this thread it seems to be a problem with
pulseaudio:
https://www.raspberrypi.org/forums/viewtopic.php?t=45548&p=360197

Are you able to run other sound applications?

[Philip Le Riche]

Thank you for that, but still no joy whatsoever. I also tried
uninstalling python-pygame and installing python3-pygame instead, but
that gave the same error and furthermore, wouldn't recognise the
existence of my wav file. I also tried installing pulseaudio,
python-alsaaudio and python-pyalsa, thinking that it looked like pygame
was failing to connect to the underlying sound system, but nothing made
any difference.

Are people successfully using pygame on the Raspberry Pi, or is it just
broken?
