The changes looks good to me, thanks.

I added an UCM file [1] to my setup to test this and tested as follows
(you can also use alsamixer but as you know this is not safe though ;)
)

# enable the speaker at bootup:
alsaucm -c ROCKCHIP-I2S set _verb HiFi
# set speaker to half loudness:
amixer set Speaker 50%
# play something
aplay music.wav
# enable headphones (disable speaker):
alsaucm -c ROCKCHIP-I2S set _verb HiFi set _enadev Headphone
# set headphones to half loudness:
amixer set Headphone 50%
# play something
aplay music.wav
# disable headphones (enable speaker):
alsaucm -c ROCKCHIP-I2S set _verb HiFi set _disdev Headphone
