Thanks for the hint. I just uploaded 1.2 to Ubuntu Jaunty (which will become
9.04).

needed (LP: #290691)

Tested on my beat-up Intrepid install and found no more cpu usage. Sound
works when needed and there were no obvious regressions. So, it works
there.
I tried to test on the current live cd, but the update had mysteriously
vanished from intrepid-proposed. What happened? It's not in the
repository
Poof! it's back. Tested on the live cd and found this bug solved with no
obvious regressions.

Thanks a lot for the rapid patch! Feel free to apply it, I will also add it to
the 1.x repository.

Accepted into intrepid-proposed, please test and give feedback here.
Please see https://wiki.ubuntu.com/Testing/EnableProposed for
documentation how to enable and use -proposed. Thank you in advance!

Based on a direct reply from upstream It look OK to me. In fact, I'll
also add it to the 1.x codebase., I'm going to package this for SRU for
Hardy and Intrepid.

Whatever the reason for the cpu usage, there shouldn't be a silent audio

Hi, thanks for answering so quickly :)
When I run it with alsa the cpu usage just shifts to mnemosyne (on a
Intrepid RC live cd):
[EMAIL PROTECTED]:~$ pulseaudio -k
W: ltdl-bind-now.c: Failed to find original dlopen loader.
[EMAIL PROTECTED]:~$ SDL_AUDIODRIVER=alsa mnemosyne

But still, opening a mixer stream which is idle should not take all the CPU
time, so I'm inclined to think this is pygame regression, as with previous
pygame versions it worked fine.
I agree that it would be in principle possible to work around this in
Mnemosyne, but the upcoming 2.x codebase
I agree that it shouldn't eat cpu when not explicitely asked to play. On
the other hand, I could imagine this being a design choice for (game)
performance reasons. The issue is probably low latency, no need to
restart the sound hardware for each bullet.
I had a closer look at the pygame and
This workaround stops it from playing any audio, including sound in
flash cards:
$ SDL_AUDIODRIVER=none mnemosyne
It shows an error but runs anyway:
Unable to initialise sound.
Traceback (most recent call last):

This is a pulseaudio/pygame issue, not a Mnemosyne one. Using e.g. the
alsa driver, I don't see this behaviour.
