Hi,
Fighting for over a week try to get the headphone sound working on a orange-pi
4b (rk3399 + rt5651-codec)
as simple-card setup. So far I got all clocks working on the i2s1 bus and use
alsamixer set Dac1 mix to HPO_L/R.
Jack plugin gpio is working correct and I see the status change in the /sys/
kernel/debug/sound/card1/Headphones Jack/status
All I got is a 'knack-noise' when starting/stopping the stream.
More details below.
Please, someone spot the missing link?
I have no idea what is going wrong.
Thanks!
Chris
To have the clocks running, there are two simple codes applied to the 6.12 kernel.
rk3399-cru.h: add
#define SCLK_I2SOUT_SRC 64
