Rock64 Stereo Audio DAC support

Hello, everything is fine, great work... but I can not get this DAC work because the card is not recognized

Just to confirm, is it the audio that's broken (rather than, say, the extra Ethernet adapter on the DAC board)? And does yours work with one of ayufan's Linux builds? If so, which one, and which kernel (v4.4 or v4.14)? Does using sudo/root help?

I sadly don't have a DAC board, so I can't test things myself at this point in time.

Do you happen to know what the Rock64 Stereo Audio DAC board requires on the Linux side? Looking at the schematics linked from the Rock64 wiki page, it looks like it uses I2S and S/PDIF.

I guess it could be:

  • Something's missing in the kernel. I've compared ayufan's linux mainline repo to Linus' kernel: https://github.com/torvalds/linux/compare/master...ayufan-rock64:master, but there's nothing that to me is immediately obviously DAC board related. I am thinking of at some point creating Arch Linux PKGBUILDs for ayufan's kernels, which may help, but that's a bit of a shot in the dark.
  • Something's missing in userland: looking in https://github.com/ayufan-rock64/linux-build/tree/master/package, there are some performance, video and udev related things that might be handy to have in general, but again, nothing that screams DAC.
  • Something else...

The DAC works on ayufan debian but with this Linux build 4.14 does not work
