I dont know what to write if i just want to play a wavefile ex. file.wav and automatically change the soundvolume from minimum to maximum.
I know how to play the file in MediaPlayer but it is the soundvolume i cant figure out.

I have found this function:
waveOutSetVolume(uDeviceID: Word; dwVolume: Longint): Word;

Please write excatly what i have to do:)

Try This:
        WORD wLeft = 0x0000, wRight = 0xFFFF;
        waveOutSetVolume(0, (DWORD)MAKELONG(wLeft, wRight));

It will set the left speaker volume to 0, and the right to Full.
