Air Mouse and USB Audio on Android

Using a MELE F10 PRO Air Mouse Remote on an Android TV Box will disable your HDMi Audio.  This is due to the fact that the MELE F10 PRO has a built-in microphone that will take over the Audio on your TV BOX.  So, unless like the ZIDOO devices, you have access to USB AUDIO to disable this function, your audio will stop working.

For user who run into this problem you can fix this by:

 

  • Install ES File explorer and edit the audio policy file to disable USB as an audio option
    • Recommend you do this with a proper keyboard / mouse attached.
    • Install and run ES File Explorer
    • Under tools (left), make sure root explorer is ‘on’
    • Click root explorer and then Mount R/W – make sure /system is set to RW
    • Then under local (left), select / then in the main window navigate to /system/etc and click ‘audio_policy.conf’ to edit it (chose ES Note Editor)
    • Click the menu and select ‘edit’
    • Find the line that starts with USB and comment out all the lines in that section like this:

    Code:
    # usb {
    # outputs {
    # usb_accessory {
    # sampling_rates 44100
    # channel_masks AUDIO_CHANNEL_OUT_STEREO
    # formats AUDIO_FORMAT_PCM_16_BIT
    # devices AUDIO_DEVICE_OUT_USB_ACCESSORY
    # }
    # usb_device {
    # sampling_rates 44100
    # channel_masks AUDIO_CHANNEL_OUT_STEREO
    # formats AUDIO_FORMAT_PCM_16_BIT
    # devices AUDIO_DEVICE_OUT_USB_DEVICE
    # }
    # }
    # inputs {
    # usb_device {
    # sampling_rates 8000|11025|16000|22050|32000|44100|48000
    # channel_masks AUDIO_CHANNEL_IN_MONO
    # formats AUDIO_FORMAT_PCM_16_BIT
    # devices AUDIO_DEVICE_IN_USB_DEVICE
    # }
    # }
    # }

    • Click back then save.

After that reboot (not sure if it’s required, but it won’t hurt).
