ALDS AudioPlayer/AudioOut How to change volume

[SleepCZ]

Hi, I have a problem and i want to ask you about some help. I am programming Music/Video Player in Builder C++ 6 and I dont know how to set/change application output audio volume. Is there any way how to change it with some component from AudioLab? I preffer it. Thanks for answer.

Hi! You can try an ALAmplifier to adjust the volume or ALSystemMixer and adjust the master-volume. If you don't use audio/video-lab components for your audio and video you should use the ALSystemMixer.

I was trying almost everything with ALSystemMixer, but i have no idea how to get somewhere where is possible to set any number value /0-100%/ or something ... dont you have any example, or where I should be looking? Thanks.

I've used this to control the master volume back on XP:
ALSystemMixer1->ControlGroups->Faders->Items[0]->Value=somevalue;

On Vista/Win7 it controls the applications volume only, range is 0-65535.

Hope that helps.
