Bug 747

Summary: Can not set channel volume louder than music

Description Ars 2009-05-29 00:33:02 UTC 
When music is playing and its volume is set, say, to 40, then channel sound is being played not louder than 40, even if SDL_Volume is set to bigger value.

Issue is seen with midi and mp3 samples.

modified playwave for example.

I can't reproduce this in the latest svn. Here's a modified version of playwave that loops a .wav file until you hit ctrl-c while playing an mp3, fading the mp3's volume in and out every few seconds.

Look for "/home/icculus" in the source and supply your own mp3 or midi.

The .wav file is attached here. Notice that the volume doesn't change, and it never prints out a warning that the volume is incorrect (so the mixer thinks the volume is correct AND it actually is).

If you have a better test case that triggers this bug, please post it here, but I can't do more with the information I have.

No response in a couple years, closing this out for now.
