You have an OpenRD Client or Ultimate ? I'll consider you have an
Ultimate.

You need to patch some files (assuming the Ultimate as a cs42l51 at i2c
address 4a like the Client) like I did in the patch sent with this mail.

I don't see snd-soc-openrd.ko and snd-soc-kirkwood-i2s.ko loaded and you
need them. Also, please give kernel boot logs if the sound is still not
working with my patch and all needed modules loaded. Checking if the
codec is still a cs42l51 at 0x4a would be nice too.
