Hi guys! Me again :)

Just a quick question:
Is there a way to play sounds on Windows Mobile with adjustable volume?
I've already found the following API calls while Googling:

SndOpen(LPCTSTR pszSoundFile, HSOUND* phSound)
SndPlayAsync(HSOUND hSound, DWORD dwFlags)
SndClose(HSOUND hSound)
SndStop(SND_SCOPE SoundScope, HSOUND hSound)

But right now I can't see a way to affect the sound's volumes. Can anyone help?

Thanks! :o

Aw, I forgot that FMOD isn't completely free :o

Maybe anyone has used OpenSL ES? That seems to be a free sound library specially for mobile phones. But strangely there is NO material on Google about it...

Google WaveOutSetVolume; its the api you need to interact with WM's sound controls:
here is the declaration:
DllImport("coredll.dll")> _ Public Shared Function waveOutSetVolume(ByVal hwo As IntPtr, ByVal dwVolume As UInteger) As Integer

oh, and use winmm.dll if you want to use the same for windows instead of WM
