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.
The drivers that I think should work with my hardware (OpenRD ultimate) are located in sound/soc/kirkwood/*.
Please remember to always CC maintainers on posts to Linux lists. I've added a CC to Arnaud and not cut any text for his benefit.
Sound on this device worked (partially) with the default software it came but not with the latest about 10 kernels I have tried.
I added bellow the output of alsa-info.sh script. If needed I can look for more or try to fix it (with some help).
Best Regards, Teodor

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.
