    I just bought a z-640 use doff of Craiglsit and have verified that all 5 speakers AND sub work ok but after connecting to the correct, at least I believe correct ports on back of pc and double checking and reinstalling audio drivers I cannot get any sound via the RL and RR channels for some reason. Can anyone help me?

    I am on WIndows 10.

    Exactly how are you plugging in the audio cable from the Z-640 to the audio jacks on your computer?

    Have you double-checked the sound controller settings to make sure you have the correct speaker mode selected?

    Did the computer come from the factory with Windows 10 or was it an upgrade from a previous version?

    What are the brand and exact model number of the computer?

    Hey buddy, I just bought a cheap 7.1 channel audio card, a SoundBlaster Audigy off Craigslist for 5$ I'll see if that works...

    Yes I set the correct sound settings in the audio panel as well as reinstalled the audio drivers as well.

    What is the audio source?

    Most mp3's, for example, are stereo (ie: front left and right - and with most surround systems also the sub). To get audio from center and rear speakers, you need a 5.1 source, such as a DVD movie with 5.1 audio.

    Windows audio needs to be configured for the correct output/speaker type (ie: 5.1). In Win7, I actually have to select 7.1 to get rear audio.

    Also, some audio drivers provide the option to create "surround" output from stereo source and use all of the speakers or quad output, which simply plays stereo on both the front and rear speaker pairs.
