Finally got audio working on my #rockchip #rk3188 tablet!🥳

@plaimbock @edvans Of course in the end the root cause was quite trivial: There are no pull-up resistors on the board and the default #RK3188 device tree configures the SD pins without pull-up.🙈

So enabling the internal ones solved all the problems.

What puzzles me is that it worked without pull-up resistors in the first place.🤔

Are there any #rockchip #rk3188 #linux experts on the fediverse?

I know this chip is ancient but I am porting #linux to one of my old tablets and experience massive stability issues with everything related to SD(IO).
