    Question How to hook up 7.1 sound on z170 OC formula

    External jacks only show front rear central bass. This results in 6 speakers.
    7.1 =8 speakers. (7+SUB)

    Can someone give me the diagram for plugging in 8 speakers to this?

    I can't post a diagram because you don't throw a bunch of speakers together to get 7.1, you buy them in a 7.1 system, so it depends on the system which there are very very few for computers.
    You're are right, you have three ports which is 6 channels.

    The reason you can run 7.1 is because the sub woofer carries the center channel and one other set or two sets of channels, depending on the system.

    If the Sub has two speakers attached and a center, that's in reality four channels on the sub even though the center uses only one channel, which leaves two channels off the Mobo for the remaining 4 speakers.

    So depending what what the system calls for off the sub is how you get 7.1 from only a 6 channel Mobo.

    If you want real sound, you run optical out to a $800.00 home receiver with a $2000.00 7.1 home theater speaker system. The dollar amount is what you want to spend, on quality, as an example.
