Re: [pygame] Mailing List Discard Tweak

[Philip Le Riche]

The only snag with sending reject replies is that it's then open to
abuse. If I took a dislike to someone (not a subscriber), I could send
hundreds of emails to the list, spoofing his email address as the
sender. He'd then get his inbox swamped. It's some standard mailing list
software which may or may not have the capability to rate-limit reject
messages.

I flagged this the other day. There's a copy on the Internet Archive at

Re: [pygame] Noob question: playing sounds

[Philip Le Riche]

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 was
one of the standard Windows sounds taken from c:\Windows\media, which
are in stereo. I imagine Pygame must be able to play stereo wav files,
given the right settings, but not with the defaults.

I eventually came across the GPIO Music Box at
https://www.raspberrypi.org/learning/gpio-music-box/worksheet/ which
contains a very simple demo program using the Sonic Pi sounds which are
pre-installed in|/opt/sonic-pi/etc/samples/|

Running my Pi headless and logging in with PuTTy I got an xcb_comection
error message, which I got rid of by typing
unset DISPLAY
at the shell prompt before launching the Pygame program.

Hope that helps. Regards - Philip

[pygame] pygame.org broken link

[Philip Le Riche]

The webmaster might like to note that pygame.org/docs contains a link to
install.html which doesn't exist. According to archive.org it
disappeared some time between Feb and July 2014. I tried install with a
capital "I" and .htm instead of .html but without success.

Thanks Miriam, but since I can play sounds with omxplayer that wouldn't

Re: [pygame] Noob question: playing sounds

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.

Re: [pygame] Noob question: playing sounds

[Philip Le Riche]

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 RPi forums and see what
anyone can suggest there.

Re: [pygame] Noob question: playing sounds

[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?

Re: [pygame] Noob question: playing sounds

[Philip Le Riche]

Well, this is strange. In
/usr/lib/python2.7/dist-packages/pygame/examples there is sound.py. This
must have worked for someone once, and it doesn't include anything about
creating a window. When I run it for the first time it makes a click but
doesn't play the sound. It produces the xcb_connection_has_error()
message but seems to ignore it.

Adding pygame.display.set_mode((1,1)) to my program (which otherwise now
is very similar to sound.py) doesn't help. This is driving me nuts!

[pygame] Noob question: playing sounds

[Philip Le Riche]

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()
sound = pygame.mixer.Sound("Exclamation.wav")
sound.play(loops = 0)
while pygame.mixer.music.get_busy() == True:
continue

Having saved it in file try.py, I do

python try.py

and get

xcb_connection_has_error() returned true

Yes, I've done an apt-get update and upgrade. I can make sounds with
Sonic Pi but this produces nothing. Googling the error seemed to give no
relevant results. Can someone give me a hint please?

Regards - Philip
