Hi Miriam -
My problem seems to have been with the wav file I was using. I'd always
assumed a wav file consisted of little more than raw binary samples, in
what case there'd be very little to go wrong, but it seems the structure
is more complicated than that. In particular, the file I was using
Hi Philip,
I appreciate the update.
Yes, I was surprised to find that WAV files are a series of chunks of
data with headers when I first looked into it a while back.
At the time I was mucking about generating raw waveforms mathematically
using simple programs to basically just build a file
I found this, which might help:

If you don't have any failures then you're not trying hard enough.
- Dr. Charles Elachi,
I got rid of the xcb_connection_has_error() by unsetting shell
environment variable DISPLAY, which PuTTy was helpfully setting for me
(for good reason in other circumstances).
The line os.environ[SDL_VIDEODRIVER] = dummy still seems to be
necessary.
However, I still get no sound. I'll try the
I did try forcing output to the 3.5mm socket using raspi-config even
though sound works with omxplayer, but with no effect. But thanks for
posting anyway - your second link contains a link to a sound
troubleshooting page which I'll follow up later.
Regards - Philip

Thanks Miriam, but since I can play sounds with omxplayer that wouldn't
seem to be the problem.
Kind regards - Philip

It just occurred to me that I recall reading somewhere that there are 2
sound outputs in the Raspberry Pi (the audio jack, and the HDMI
connector) and that some people have had difficulty switching between
them. You are probably trying to get sound from the audio jack. Did you

Ah. Then by elimination it does seem that python/pygame on Raspberry Pi
is the source of the problem somehow. Good luck. Let us know when you
solve it. I have a Raspberry Pi too and though I haven't got around to
playing with python and pygame on it yet, I hope to in the future. :)
Cheers,

Thank you for that, but still no joy whatsoever. I also tried

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?

This has happened to me too on several occasions. I have resolved this by
1.pygame.mixer.pre_init(44100, 16, 2, 4096) # setup mixer to avoid sound lag
2.pygame.init()
3.pygame.mixer.set_num_channels(64)
Try deleting the name of the file completley and renaming it. Sometimes

to do most things with pygame you need to initialize a pygame window.

Just trying to get started with pygame and stuck at square 1. All I want
to do is play sounds on a Raspberry Pi (Raspbian). No screen. Nothing
visual. So I do:
import pygame, os, sys
from pygame.locals import *
os.environ[SDL_VIDEODRIVER] = dummy
pygame.mixer.init()
