To get USB boot mode hold two buttons (in powered off state): 'Power' and 'Forward' (>>)
To get original recovery hold two buttons (in powered off state): 'Power' and 'Volume Up' (Vol+)

Boot log in attachment and here is DAC/Audio related part of boot log:
I have no clue how to deal with FPGA based buffer since I didn't find any of completed Rockbox port on Ingenic SoC with SA2000/HBC2500 FPGA. There is reference to HBC2500A on ShanlingM2s https://www.rockbox.org/wiki/ShanlingM2sPort.html but the page https://www.rockbox.org/wiki/HBC2500A.html is missing.
Note: original firmware v2.2 is for three version of R3Pro - first revision has cs43131, second revision has es9218p and 2022 revision has es9219c.

There are 7 input devices. I think we have to care about only two (three) of them - buttons related devices and touch screen device.
There are also remote control by wired earpods and accelerometer but I don't think we really need this in Rockbox.
There was disappoint that only tho physical buttons are on GPIO, the others are related to unknown ADC device.
