No Audio over Analog ( Jack OUT ) M8 s802 amlogic box

1st Official Post

    Hi to all firiends.

    i have this old m8 s802 box and would like to use in my bedroom.. i would like to use an external ( stereo ) amp.. this amp does not have any digital options as input so i need to use the analog output from this box..

    in android audio was always working.. but in non OE or LE versions i have seen this working..

    i hope some one is willing to help me out.. as i don't want to use any external DAC or other device..

    and of course i am willing to do anything what is needed to be done like logs or testing..

    Some info :

    LibreELEC-M8:~ # aplay -L

    Our 3.10 kernel has been hacked enough to make HDMI and S/PDIF work properly but analogue audio was not a priority. There are no plans to go back and fix that among any of the staff devs. Community contributions are welcome.
