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

    creative+emu
    SB Live! and Audigy
    To install, run creative script. Reboot is not needed. To uninstall run uninstall creative and reboot.
    To record, launch the kX AC97 app and select the microphone or line source in Rec. The correct input sampling rate is 48 kHz.

    E-MU
    To install, run the install emu script. Reboot is not needed. After installation, you need to run edspctrl. To uninstall the installed files, run uninstall emu and reboot.
    Initialization at start is incorrect. The solution is to switch the frequency to another and back, then it works correctly.
    Input sample rate: 44.1 -192 kHz
    Output sample rate: 44.1 -192 kHz
    SPDIF - 2 channels, up to 96 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, High Sierra, Catalina.

    HQ
    HQ is a test version of the driver with support for the CA0151 chip, only for the Audigy 2 / ZS card line (except for the Audigy 2 value), Audigy 4 Pro (not tested) . Playback at 48, 96, 192 kHz without resampling, 2 channels. Recording is not supported.

    Ok, I will do this a little later.

    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.

    I am the author of that driver and with my version of alejandro's driver i will contnute to support a wide range of sample rateds with the consumer cards (from 7khz up to 176.4 khz), professional cards are limited to 44.1 khz and 48 khz as sample rates, as said by alejadro they require a different tecnique to switch sampling rate, so this limits such cards to just that 2 rates.

    For consumer grade cards we need also to figure out the corrected values for the sample offset and the n_frames to solve the cracking issues and to add sample rate switching for the inputs (if some one knows how to do that i will be very happy to add it into the driver), but the new driver looks very promissing to me, it has not a lot of the issues of the old one.

    Added 192kHz for playback for Audigy cards. Recording only works at 48 kHz.

    Good to know, is your sorce code on github updated, so i can start play with it?

    And also there are a couple of user's features request, i think it's worth adding to your branch of the driver, i'll pm you.

    Owners of Audigy 2 cards (not Audigy 2 value), you can try the driver without resampling, see the HQ archive. Playback frequencies - 48, 96, 192 kHz. Recording is not supported.

    If someone has a crackling sound while watching a video on YouTube, try the new version of the driver.

    I added 44.1-192 kHz support for E-MU cards. This driver is for e-mu only, it is currently not compatible with the Sound Blaster series.

    Hi! Are you testing headphone or line out? Headphone out does not work for 1820. Line out should work but I haven't tested.

    I updated driver, "e-mu only" version is no longer needed.
