There's an upstream commit (part of 5.12) that Vincent referenced that nicely
illustrates the difference between what I want to achieve with this bug report
and a possible solution applied in that commit (IIUC):
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=25572fb5aa986bdbb35d06c0fb52a9b9d9b3b2c9

In that commit there's a switch from 'audio-graph-card' to 'simple-audio-card'.
If that change were applied to Debian, that should make the audio work (too)
on a Rock64. And if upstream would backport that commit to 5.10, Debian would
only have to upgrade to a latter 5.10 version to get it.

But there's a line in that commit message that illustrates what I want to 
achieve with this bug report:

"For newly adding nodes, ASoC guys recommend to use audio-graph-card."

What I get from that and is what I assumed previously, is that 
'audio-graph-card' is seen as 'basic building block' for audio in SBCs.
(Just like 'simple-audio-card' is). And that is why I want it enabled in 
the Debian kernel(s).
Just a 'backport' of above referenced commit would fix my issue on my Rock64s,
but afaic it wouldn't fix this bug.

Cheers,
  Diederik
