This may sound like a dumb question...
I recently got the starlogic 5.1 usb sound card and while checking out the connections etc, I noticed that all the negative signal for front, rear, sub and center are all the same. i.e. they are from one continuous output.
I don't know THAT much about speakers but I thought each speaker ground should be independently connected to divide the audio respectively into 5.1 channels.
Any experts out there?
