No sound in RioTboard (Android)

Former Member

Hello,

 

I recently started with RIOTBOARD. When I connect, image and network speed was great, however I have no audio when playing videos on youtube or anywhere element14 not work either, even connect music with a USB that is "played" but no sound any.

 

Does anyone have some advice?

Does anyone else have this problem?

    I did some research and it seems that the Android Image ist missing some Settings to get Sound output over HDMI.

     

    If you can connect on the board to the console you can type this:

     

    setprop ro.HDMI_AUDIO_OUTPUT 1

    setprop sys.hdmi 1

     

    The sound should then work. (Can´t test it right now)

     

    Problem is those settings are temporary. After a reboot it´s not working anymore.

     

    You need to set the system partition as read-write and change the settings in build.prop to make it permanent.

    But for that it seems root is needed?
