DirectShow set Volume with multiple channels

C#

Hi,

I’m new to DirektShow in .NET, but so far I made very good experience with it.

I am currently writing a little player for sound and video, just to get a grip on the basic functionalities.

The first real problem I encountered is the Volume control.

I use the “IBasicAudio“-interface and the “put_Volume”-function, were I set values between -10000 an 0.

For most Audio and Video this works pretty well to controll the volume level.

However, I have a few .wav-files that are multi-channel (up to 6-channels), and when I set the volume here, only one channel changes volume.

Before I load the File, I select a certain output-Device (DsDevice) that will be used to play the sound.



So I would like to know, if it is somehow possible to set the volume for all channels, or to use DirektShow to set the volume of a DsDevice. Which ever is easier.



Best Regards, Marc
