Another member here suggested,

"The settings outlined in here
https://volumio.org/forum/es9018k2m-...ion-t2087.html
with an ESS K2M and Volumio 1.51 and it worked with the Soekris - I simply connected the i2s to pins 12, 35, 39 & 40".

It did not work for me on the rpi 2 but it may work on the earlier models.
It also seems that Volumio, Rune, and Archphile will not play 16 bit over i2s. I changed bit depth to 24 on a few tracks with sox and they worked after. Unfortunately they sounded worse for the extra processing.

I loaded piCorePlayer to Rpi 2, set up i2s, and connected to Logitech Media Center online and it worked like a charm. Easy instructions here, including i2s setup:

Also another member has endorsed Voyage MPD:

It requires a linux computer to set up. I will be excited to try it!

Subscribing - Subjects I need to learn more about
  • Recommended text screen and needed libraries to use with piCorePlayer
  • Libraries needed for RS232 communication with DAM1021

I did not manage to connect to the dam1021 with UART from the GPIO with raspberry pi2. I think it is because that the rs232 in the DAM needs 5v. The rs232 from Raspberry is 3.3v.
Søren said that next firmware would fix this.

But an usb-serial adapter in the RPI worked fine with the DAM.
Using minicom as "emulator".
"pacman -S minicom" - if you got an arch distro.
Here is a good description

Reposting my question from the implementation thread.

Did anyone manage to get Rpi -> I2S -> Dam1012 to work?

Yep, from day 1 I've been using Squeezeplug on the RPi > I2S > Dam1021, worked first time!
