Hello guys. I installed new debian 11 on my old cubox 510, how can i make it work s/pidf audio kirkwood? It only worked on kernel 3.6.9, anything newer does not include a driver for this audio.

This Cubox 510 is not a Kirkwood. It's Marvel Dove SoC. We have a thread for the HP Thin Client T5335z here:

https://forum.doozan.com/read.php?2,66989,116839#msg-116839

The older kernel 3.6.9 is most likely a non-FDT kernel, so s/pidf audio is enable in the kernel setup code. The later kernel are FDT, so all devices, including audio, are defined in the kernel DTS.

Since you mentioned installing Debian 11, I assume you installed mainline kernel, using Debian netinstaller or CD?

I'll take a look at the mainline Cubox DTS to see if I can tell why s/pdif does not work.

OK. I've looked at the mainline Cubox DTS (arch/arm/boot/dts/dove-cubox.dts). It does not look complete as far as sound system is concerned. That's probably why normal audio is working, but not s/pdif.

I have not tested the HP Thin Client T5335z sound system yes. But I recall with its cousin HP Thin Client T5225 (Kirkwood SoC), there is a lot more than what the Cubox DTS has right now. I did test the HP T5225 sound system and s/pdif was working.

For the HP T5335z (Dove SoC) DTS, see the patch linux-5.16.5-mvebu-tld-1.patch in the release thread: https://forum.doozan.com/read.php?2,32146.

For the HP T5225 (Kirkwood SoC) DTS, see the patch linux-5.16.5-kirkwood-tld-1.patch in the release thread: https://forum.doozan.com/read.php?2,12096.
