iMac not recognizing USB Audio CODEC for Multimix8 USB

Been using your Mulitmix8 for several years (it's silver) with several macs thru the years. Recently the iMac has stopped recognizing the device. I can see the USB Audio CODEC, but it says there are no input devices. From my online searching, I'm quite sure this is Apple's fault, but I can't find a good solution. I'm hoping your company is a bit more responsive. Do you know how to fix this? Running Yosemite 10.10.5.

  • Hi Sven,

    Thanks for posting. 

    Make sure your MultiMix is connected directly to your computer's USB port and that you aren't going through a hub. Try using another USB port and cable, as well. Since the MultiMix 8 USB is class-compliant, it won't require any drivers to communicate with your computer. Please refer to the link below for troubleshooting class compliant devices.

  • Yes, plugged directly into iMac and used a new cord. Went thru the check list and this is the answer. "If the device does pass the test above and appears in the System Report, it is not defective, and the difficulty is caused by misconfigured software settings or options." So it is a misconfigured software setting or option. Kinda what i figured. Still need a lil help.

  • Try creating a new MIDI configuration:

    Before getting started, disconnect all USB or Firewire MIDI devices or keyboards. This will eliminate any potential conflicts upon creating a new configuration.
    1. Open the Audio/MIDI Setup by going to Applications > Utilities > Audio/MIDI Setup.

    2. If the MIDI Studio window does not appear automatically, go to the menu bar at the top of the screen and select Window > Show MIDI Window.

    3. The MIDI Studio window will pop and display all of your current MIDI devices. 

      MIDIStudio Config1

      You may see icons for all of your MIDI devices that have been "greyed out." This just means that the devices are not currently connected. If a device is not connected to the computer but still appears connected in your MIDI Studio, that may be a part of the problem and a sign that the MIDI Studio needs to be reset.

      Please Note: The IAC Driver and Network will always appear in the MIDI Studio.

    4. To create a new configuration, click on the Configuration drop-down menu and select New Configuration...

      MIDIStudio Config2

    5. Name the new configuration in the window that appears.

      MIDIstudio config3

    6. Click OK and the MIDI Studio will rescan your devices. If nothing is connected, only the IAC Driver and Network should appear again.

    7. Starting with the device in question, re-connect each device one by one. Wait for the device to show up in the MIDI Studio before connecting the next one. Hint: you can also use the Rescan MIDI button at the top if a device is still not showing up while connected.

    8. And that's it!
