I have a question:
I'm using an USB external Sound Card (http://www.sweex.com/en/assortiment/sound-vision/sound-cards/SC016/) and it's SW is not working on one of my PCs(running win XP), so I figured: I want to do a simple application. The main point is to set different
volume to each speaker. So when I have 5.1 I'd like to change the volume on each speaker independently(that means control the volume on center speaker, on sub-woofer, etc.). I was able to get this working for a 2 channel output (left and right)
but when I plugged 5.1 speakers it controlled them the same(so when I lowered volume for left speaker the surround left went off too, and sub-woofer too).
I used something like this to change the channel volume:
MMDeviceCollection devEnum = DevEnum.EnumerateAudioEndPoints(DataFlow.Render, DeviceState.Active);
devEnum.AudioEndpointVolume.Channels.VolumeLevelScalar = (float)trackBar2.Value / 100;
And now the question: Is it even possible to get this done? Or do I need to make my own drivers for this external USB sound card?
Thanks for your answers in advance.
