I have a Tv Box V88 4K with the firmware rk322x_box-userdebug 6.0.1 MXC89L and is connected to my tv by HDMI. The prblem is that the sound wont work. Neither in kodi or in youtube. I try change the HDMI cable and it wont solve the problem.
I read somewhere on internet that i had to set the digital output to HDMI but the weird is that i cant find that setting in the android 6.0.1.
Can someone help me?
