Relevant detail:

"Because this is for unit test, I have the effects on a button press.
So it's very likely that Mix_SetPanning() gets called multiple times.
No other effects were set on that channel.

Here's the flow:

Mix_OpenAudio
Set volume to MAX
Allocate 2 channels
Load the 2 different chunks (1 on each channel)
Load the music
Play the music (loop forever)
Play chunk 0 on channel 0
(while sfx is playing) Set Panning on both channels to (255, 0)
Halt Channel (passing -1, i.e. halt all channels)
Free chunk 0
Free chunk 1
Mix_AllocateChannels(0) // free all channels
Halt Music
Free Music
Mix_CloseAudio


Cheers,
Kos"

Whoops, this is an SDL_mixer bug, not an SDL bug...

Ryan, can you take a look at this for the SDL_mixer 1.2.8 release?
Comment 3 Ryan C. Gordon 2007-07-15 07:43:05 UTC

test case.


Here's a test case that triggers the bug. "whoosh.wav" and "icculus.org" can be just about any file you have laying around your hard drive.
