Audio Device, change Speaker setup

Question

Hi Guys,

I want to change from my program the speaker setup, which is under speaker settings / advanced... section.

I tried to find maybe there is some sort of registry entry but no luck till now :|

Any Ideas ?

Thanks a lot !

Answer 1

I found this old thread about people failing to do this under Vista.

It seems that it is possible using DirectSound using XP though and someone claims he managed to find a hacky way to do it under Vista.

Answer 2

Ok, here is the code for what I wanted

var ds:IDirectSound; begin if DirectSoundCreate(nil, ds, nil) <> DS_OK then raise Exception.Create('Failed to create IDirectSound object'); ds.SetSpeakerConfig(1);
