Hi,
today I found out that the rpi-update script that is available on Raspbian will attempt to bump the kernel to 4.19.y. I understand the ADC+DAC kernel driver has been mainlined some time in 4.18.
Does that mean it is no longer necessary to run your custom update script in order to use the ADC+DAC, just sudo rpi-update?
Hi,
the 4.19 kernel should already include the DAC+ ADC driver. I haven't tested this yet, but as it has been merged some time ago already into 4.19, I don't see a reason why this shouldn't work
Best regards,
Daniel
It's been a while, but I can confirm that on a current Raspbian that has been updated to 4.19.y using "rpi-update", the DAC+ADC will work out of the box, provided you have added "dtoverlay=hifiberry-dacplusadc" to your /boot/config.txt.
