    Hi all! Owners of E-MU 1616, test this version of the driver.

    Analog inputs work. Supports 44.1-48 kHz.
    The mixctrl application (test version) has a mixer and switches of the levels of inputs and outputs pro / consumer. The hardware limiter also works.

    Tested on the Mavericks and High Sierra.

    To install, unpack the archive and run the install emu script. Reboot is not needed. After installation, you need to run edspctrl. To uninstall the installed files, run uninstall emu.

    For SB Live! and Audigy requires the kX AC97. Use install creative in attachment for them. For input select mic or line-in in Rec.

    Alejandro! You are the Best!
    First, thank you for the working inputs in E-MU 1616! (my card is 1616m) You make my day! ))

    But, I have a problem with your driver. When I watch videos (for example) on YouTube. I hear a crackling sounds.

    Solution: Need to change n_frames values. From -2048 to -8192.
    Here is link to fix it in code: https://github.com/herrnst/kx-audio-driver/commit/aa1a4d6ee2302de4d0e30375c28a73bcfffc9c20

    I was make a little changes in your binary file (Because I don't have your sources), and attach it to this message. Now, it's works fine for me. ;)

    Also, some guys make another version of this driver here:
    https://www.insanelymac.com/forum/t...mod-sound-blaster-live-audigy-124rx-emu-edsp/
    It would be great if you joined them. Their version supports multiple frequencies:
    64000, 88200, 96000, 176400, 192000, 8000, 9600, 11025, 12000, 16000, 18900, 22050, 24000, 32000, 37800, 44056, 44100, 48000 ..

    P.S. I hope, you will continue to work of this driver. Thank you!

    Hi dynaudio! My card is 1616m too. I saw that the buffer increased 4 times. I reduced it as was initially and no problem with sound. My MB is ASUS P7P55D. Was tested Audigy (sb0090) with other MB, everything is good too. Increasing the buffer increases the latency. Perhaps problem it's not in the driver, maybe with interrupts, or something else. Try another pci-e slot, if possible.

    Why so much, does anyone need this? :)
    SB and EMU use different algorithms for switching frequencies. EMU should not use oversampling.

    Updated kX AC97.app. The red button closes the application. Fixed crash when closing.
