using EQ on music streamed from internet

I don’t know how to change this. When i select a channel in the Hardware Output section of totalmix and then turn the fader down on AN 1/2 channel in Software Playback section then that Hardware Output channels level goes down. So i selected the AS 1/2 channel in the Hardware Output and then turned the fader down in AN 1/2 on Software Playback. So now in the Hardware Output section i only have the level meters active on AN 1/2 channel and the Main Channel. But i still don’t know how to set up the Windows playback channel and the Cubase playback channel.
