    JUST FOR GAMING - no music or movies

    My display is fed via my 2 x gtx 1080ti in SLI (34" ASUS)

    My audio can either run via

    ASUS Rampage V extreme onboard optical

    OR Soundblaster Z

    OR Soundblaster ZX

    To a Yamaha 5.1 receiver (optical and HDMI)

    I know HDMI will give me better sound quality (no compression)

    BUT

    How in the world do I set it up?

    My assumption is use the 1080 HDMI port for sound to the receiver and Dp to the display.

    I run the cards in SLI.

    Should I sell off the soundblasters if I only use optical to go to the amplifier?

    So confused.

    Use trial and error. Great tool for solving problems.

    If your receiver has analogue input I would use that with one of your SoundBlasters so you have control over software audio enhancements.

    Couldn't you go optical from onboard to receiver? You can then use DP/HDMI to connect to the monitor and then disable DP/HDMI audio output in Windows Playback devices or set the optical audio as the default playback device. I think you could do something similar using DP->monitor and HDMI->receiver

    I think optical is the same quality as via HDMI unless you have Dolby Atmos etc. but you did say just for gaming so that's not a problem.

    Optical can only do 2 channels of LPCM, whereas HDMI can do 8 channels. To get >2 channels over optical you need to use DD Live or DTS connect to encode and compress it before transmission.

    Yeah, good point. I guess it depends on whether they want to use surround audio in their gaming setup.
    Either way the solution is the same, just specify the default playback device in Windows and it should work.

    Did you get this going with DP out to display + HDMI out to receiver?
