    Hi !
    I've install APO to get a little amplification and bass boost. I own a logitech g433 who get an external usb sound card. Everything seems to work great until I test it ingame. I don't hear when the sound come from behind me. My g433 propose 7.1 DTS but I don't use it. It also have an app named G-Hub but isn't as that much good. I've done a little draw to show you what type of sound I can't hear. In red this the sound I can't hear.
    I hope you have understand what's my problem and if someone can fix it !
    Thanks for your time !

    It happens that just now someone else fixed the same issue. I've posted this to to help him out. It seems that the surround sound effect of G Hub is the cause. By unchecking the "Use original APO" checkboxes of the troubleshooting options in the Configurator for your Logitech G433 the surround effect of G Hub is bypassed. Do you know how to do this?

    It could be that you need additional step if this doesn't fixed it. This is downmixing done with the below commands but first try the above without doing a downmix.

    Copy: L=0.350*L+0.157*C+0.022*SUB+0.210*RL+0.261*SL
    Copy: R=0.350*R+0.157*C+0.022*SUB+0.210*RR+0.261*SR

      Thanks for the answer !
      I'm sorry, I don't know how to uncheck the "use original APO" checkboxes...

        No problem, I'll explain. The Configurator of Equalizer APO, the app that you already have saw or used at installation, has some troubleshooting options for each device. Basically the Configurator (which you'll find in the Windows Equalizer APO menu) has 2 tab pages containing playback devices (speakers, etc.) and capture devices (usually only mics). By clicking the device name in the connector column (next to the left checkboxes) the Troubleshooting options checkbox can be checked. Then these options will appear below this checkbox.

          Thanks for the explaination I found it ! Uncheck it, restart my computer and the problem is still there. I have no idea about how to do a downmix. I search a bit in the Equalizer APO folder and found in "config">"selective_delay.txt" some line where I can put the downmix you told me about. Is that what you mean ?

            Also in the "multichannel.txt" I only see chanel L and channel 2 C. Isn't there any missing things ?

              By default the config folder of Equalizer APO doesn't contain any useful configuration files. If you were to use Peace, an Equalizer APO interface, then many configs are available. In fact, downmixing is as simple as flipping a downmix switch on the Effects panel of Peace. But downmixing is also possible when using the Configuration Editor of Equalizer APO. First put the downmix commands I've stated into the config.txt file. After saving the downmix becomes active. And if you want to change it either edit the file or open the Configuration Editor and change it there.

              One other troubleshooting options you should try if the downmxing doesn't work. Set the "Install as" checkbox to SFX/EFX when on Windows 10.
