Thought I'd report some issues I've found which seem buggy - hope that's ok.
SetMusicChannelVolume definitely doesn't appear to work for me - I've tried the same .dcp on Windows (XP), Mac OSX (Lion), and my iPod Touch - the volume level is simply not affected.
Also, the master sound volumes for Music, SFX and Speech, all appear to be the same, even though I have set them to be different.
The next 4 problems only seem to occur right after changing scenes.
I'm getting a lot of sound issues on all platforms - mostly random bursts of static and pops.
In OSX, sometimes after clicking to chang scene, there was static/pop and the scene didn't change - the screen faded out like normal but returned to the scene I was already on - if I clicked again, the scene changed normally. Didn't notice this in Windows or iOS.
Also getting some graphical glitches randomly - bars of colour across the screen, that kind of thing.
And the most worrying one - at one stage, in Windows, the game completely crashed on me - I clicked to change scene and the screen just went black, and I couldn't get out of it without turning off my computer.
Strangely the above 4 issues seem to be worse the first time I run the game - after that, they appear to lessen - first time on Windows, I was getting sound static and pops all the time, plus the crash - 2nd time, only one pop, and no crashes - I played it longer the second time. Same thing happens on the iPod - major sound issues (pops, randonly restarting music files, randonly jumping to another music file) the first time I load it - next time, no issues at all. Weird.
Any ideas about these issues? Sorry if I've been vague, but that's all I have.
Oh, and the game appears to run MUCH faster on Windows with WME Lite - is this normal?
