I only got a "applied" reply from Marks scripts for patch 3/5, so only today saw that all 3 actually got applied.
Anyway, I've applied this to my dts32-branch for 4.8 now [0] with some modifications regarding
- the commit subject+message
- ordering
- io_domains access (via the phandle now)
- regulator suspend property
so maybe take a look and holler if you see a mistake.
The changes looks good to me, thanks.
I was able to get audio over the headphones (so definitly an improvement), but so far not over the built-in speakers. Did you need to do something special in the configuration for this?
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
woohoo ... sound on the speakers :-D
Thanks for the hints Heiko
