Make sure your selected microphone is connected to your computer. See Microphone modes for more information. If the button is blue ( ), the microphone is in sleep mode.

To use a Bluetooth audio device, you must have a USB adapter (dongle).USB devices must be plugged directly into your computer.Nuance encourages users to dictate using the internal microphone where possible. All iMac and MacBook computers have excellent built-in microphones.If your microphone is not on this list, Nuance cannot guarantee that it will work with Dragon for Mac. Talk to the manufacturer of your product and bother them until they provide these firmware files to you, or see if you can find out which particular chip it uses and if there are files floating around online.Troubleshooting audio and recognition Supported DevicesĪ complete list of Nuance-supported devices is available at. "UAC3556B", "UAC3576B" or similar is Trident/Micronas.) ("USB Advanced Audio Device" is one of several C-Media chips. You can most likely fix it (temporarily?) by re-burning the firmware, but this requires obtaining the firmware image and a burner software for your particular USB IC. This means the EEPROM chip that stores the firmware has failed, or become unreadable for some reason (Power spike? Poor quality EEPROM with bad data retention? Cosmic rays/radiation? Tin whiskers? I don't know), and the USB chip has reverted to its generic default program. (You can prove this by plugging it into a different computer, especially one with a different OS, and it will still identify as the wrong name.) If you search for these names, you'll see that products by a bunch of different companies are affected. When a device identifies as "USB Advanced Audio Device" or "UAC3556B" or "UAC3576B", this is not a driver issue it's a firmware/hardware issue.
