With the regulator claiming the pin, the amplifier stays off and the headphone jack is silent. Patch 1 moves the regulator and the sdmmc vmmc-supply into rk3588s-orangepi-5-5b.dtsi, which only the 5 and 5B include. The compiled 5 and 5B DTBs have the same nodes and properties as before. Patch 2 describes the amplifier as a simple-audio-amplifier aux device on the Pro and routes the headphone path through it. Tested on an Orange Pi 5 Pro (Linux 7.3-rc7): SD card boot and analog headphone output both work.
