    I'm also having that "extreme" memory allocation problem. It always happens when I double click in some DSP effect.
    It also happens if when I boot the machine and that effect's window (it's config) opens (when the user logs in). In that case I don't have any program generating sound (excluding Windows itself, but I don't have it set up to play login sounds).

    It seems the "kx.mixer" is trying to allocate the maximum amount of virtual memory possible (it hits my virtual memory limit, ~16GB) so it hangs my PC for some minutes (about 5) until it starts to respond. The same symptoms has other people are having (it seems).

    Is it related to some graphical stuff? (windows handles) I don't much of windows programming, so I'm not sure.

    The moment I remove the effect I added (before the problem) all comes back to normal, for instance (now, after it has happened) about 124 MB Virtual memory, 344 KB working set and 10 MB private memory, used by "kxmixer.exe" (reported by process explorer). Before, you can see the usage in the screenshot. In the screenshot, the "problematic" effect is "ProPhaser" and is between the 10B Equalizer and gainHQ (outside the screen). Check the link:


    I'm really looking forward for the solution of this problem, as it has happened a lot of times before (and it will happen again, for sure...)

    Kind regards,


    My hardware/OS:
    Intel Core i5 750,
    6 GB DDR3,
    Gigabyte GA-P55-UD3R,

    Windows 7 x64 updated (latest).

    the not working volume/muteknob on my breakoutbox is not the only problem.
    It seems, that volume/mute keys on my multimedia keyboard and on my steelseries "fang" gamerkeyboard does not work too.
    The only effect when using this keys is popping on the OSD but with no effect.

    after installing the 3550 driverpack, i had to copy all the files to system32 folder to get ASIO to work.

    My System Specs:

    Win Pro 7 32-bit
    2GB Ram
    Core 2 Duo E6600
    Audigy 2 ZS Platinum Pro
    kX Driver 3550

    1.) can someone confirm problems with this knobs/keys?
    2.) or can someone confirm that everything whith volume/mute knobs/keys is fine on win7
    3.) does someone knows, how to fix the problem with the volume/mute knobs and keys?

    Sorry for my english

    KX Driver 3550, windows7 ultimate, AMD X2 4400, gigabyte M55 plus S3G.
    E-MU 0404 PCI + Live 5.1.

    Asio, EMU 0404, foobar 2000 (vol=max), Signal level out of range, a little signal distortion presents. If playing to master mixer, it`s Ok (vol=max).
    Real signal level in Line Out Asio > Master mixer = x2.
    Playing formats - Flac.

    After starts Windows is no sound. Sounds is works after pressed button "Reload Firmware" in E-DSP control.

    I can`t play signal from line in, i want make trasit sound and here line in signal on line out.

    Live 5.1 default playing in "black" out (0/1). I`m set (2/3) but this option no save after windows restarts.

    Very Thanks for your work!
