Hi everyone, a curiosity .. I recently got a Logitech z906 mounted on a sound Blaster Z sound card .. connected with 3.5 cables, because practically all games there is always a much lower sound than the rest .. for for example, the boxes that break .. the rustle of the grass,footsteps, things that in stereo you hear loud and clear in the surround sound low .. but it is not the volume problem of the speakers, those are balanced .. any explanation? thank you
