Re: Bought 4 different Rockchip players- none come with F/Wa
On page 7 of the Rock Datasheet you can see that there is a special pin for
sensing the insertion of the jack plug, which means that it can be all controlled by firmware instructions to the Rockchip itself, so no need for any mechanical switches.
it's pin number 81 "HP_SENSE I Sense of jack insertion"
Problems in this area could mean an incorrect or corrupt firmware has been installed.
