Full of hope, I did "aptitude install mp321" which went without any visible problems.
Then hooked up a pair of earphones to the "speaker" plug on the Client and ran

So it seemed to be running OK... But there was no sound in the earphones. I also tried adding option "-g 50" to set the gain explicitly. Still no sound.
Is there a hardware jumper I need to set to activate sound on the OpenRD Client board?
On my board I need to say "amixer set PCM on". Can you post the full output from "amixer" without any parameters?
Also check if you have this line in dmesg:
asoc-simple-card sound: cs42l51-hifi <-> i2s mapping ok
If it says "spdif" the player runs but is silent.
