mic input device not find

When I download \nRFready Smart Remote 3 nRF52 v1.2.1alpha\nRF5x SDK-SR3\examples\ble_peripheral\smart_remote_3_nrf52\Projects\Firmware_nRF52832 to my 52832 device, I can't find the mic input device on my computer, either Windows or Linux. What's going on here

  • For Windows, this is correct, as BLE Audio Profile is not supported in Windows on Smart Remote 3 (SM3). This information may not be clear with the quick-start guide. Only touchpad, buttons, and gyro work in Windows. Have you configured the SM3 audio for Ubuntu? Does the SM3 show in Ubuntu at all? 

    The Quick-Start guide states:
    The Product example comes with pre-installed firmware. For a quick start with this device, just insert batteries, and continue reading in Pairing with Windows (basic use) or Pairing with Ubuntu (use with audio).

    Let me know how that works.

  • Ok, then you will need to configure your hardware accordingly. Attached are two files that you need to save in the following folder:
