Hi guys,
I admit the logitech X540 5.1 manual is awfully discreet about the matrix functionality.
I had the same problem as many here, until I figured out how that "matrix" mode works:
- if you do not enable the Matrix mode (the switch at the right on the volume control) you will not hear anything in the rear speakers when listening to a 2D source (music, streaming video, or most divx formats)
- on the other hand if you enable the Matrix mode and listen to a 5.1 dvd movie you will just not hear some sound.. or very low. Like you will barely hear the voices for instance.
Conclusion:
Enable matrix most of the time, unless you know the source is 5.1 (dvd or mkv movies, and in games I guess...)
The matrix mode is here to mix any left-right stereo sound into a kind of surround sound.
Too bad the driver does not detect automatically if the source is 2 or 5.1...anyway.
What is even worse is the impossibility to rebalance the sound volumes in Matrix mode.
Voyd, I use Realtek HD Audio manager as well but I do not see any where the option to enable a "speaker fill option" nor the possibility to set speakers to "full range"..(what does that mean anyway?). This tool sucks!
I'd like to boost the rear speakers as well, the front-rear balance is really bad, it actually does not "surround" anything because the volume of the rear is barely hearable.
Any advice on that?
