NO /boot/config.txt - jeffjazzer - 01-Jul-2019
Trying to get digital output to function on my add on card with the pi3b
Card is not shown as an ALSA output device.
I'm running Snakeoil on a pi3b. Snakeoil ALSA choices I have are
bcm2835 ALSA
or
bcm2835 IEC958/HDMI
which I believe are from the pi3 itself not my add on card.
The card uses the standard CM5122 driver and needs to be configured to the Hifiberry DAC+ setting.
I've made it into the terminal and read on the forums how to change settings in /boot/config.txt
Problem is I am unable to get that text to display to make changes.
Thanks for any help from a newbie.

OK I got in by using
sudo nano /boot/config.txt
looking for an overlay for my card
RE: NO /boot/config.txt - Bromf - 01-Jul-2019
I thought there was a readme in /boot/config.txt that had the overlays available listed....?
However, RPI overlays are listed here....
https://www.raspberrypi.org/documentation/configuration/device-tree.md
For your requested Hifiberry DAC+
add a new line to /boot/config.txt (copy and paste below)
Code:
dtoverlay=hifiberry-dacplussave ('ctrl+o' to writeout the changes. 'Enter' to accept the change, and 'ctrl+x' to close the terminal) then reboot and it should work.

This gives me an idea. :) I'm going to add this as an experimental feature for U7 - add ability to modify /boot/config.txt.
