[QUOTE="doveman, post: 822573, member: 67412"] I'm having trouble with ffdshow and my Realtek control panel. I want to set it to 5.1 in the control panel with only Center ticked as shown in the attached picture (I've only got three speakers connected at the moment) and then use ffdshow profiles to switch the mixer settings between Mix all to Stereo, Mix all to Stereo except Centre, etc. When I add some rear speakers, I'll want a Mix to 5 speakers profile as well. The problem is, as soon as I tick Center in the control panel, I lose most of the volume on L&R, like the two channels are cancelling each other out. This seems to be confirmed by the fact that if I set the R->R column to 0, the volume goes back up to normal on the L speaker. I've also tried all the options under Output Speakers Configuration but none helped. The Centre speaker (amp connected to Blue socket, assigned as Centre/Subwoofer Out) is working OK and if I untick Center in the control panel, this gets added to L&R, boosting the volume but not cancelling it out. If I tick Rear pair instead of Center (and assign the Blue connector to Rear Speaker Out), set Output Speakers Configuration to 2/0/2 Quadro and direct L->Back L, I can get sound out the Center speaker and the L&R speakers work normally but this isn't going to be any good when I add some rear speakers. This also works with 3/0/2 - 5 channels and sort of with 3/2/2 - 7 channels (but it's a lot quieter) whilst with 3/2/1 - 6 speakers I have to direct L&R to Back C instead to get any sound out the Center speaker, which doesn't make any sense. I note the Volume filter doesn't have a slider for the Back Center channel and when I direct sound to this channel, it's shown in Volume on Back L.
