We're not on pulseaudio ... likely pulseaudio checks for ak4613 .

Subject: [PATCH 056/122] ARM64: dts: renesas: ulcb: Make AK4613 sound device
name consistent
This makes AK4613 sound device name consistent throughout all
ULCB boards. This helps to avoid naming issues when pulseaudio
fails to start because the device has different names on
infotainment and starter boards. For example, "ak4613"
on Kingfisher vs "rsnd-sound" on Starter Kit.
Pulseaudio is expecting "ak4613" name.So there are probably good reasons to keep the change due to pulseaudio. AGL will have to live with that diff.

There's no confusion here.
Status is as follows:
for ebisu (and probably salvator), sound car name in asound.state must be 'rcarsound' (cogent layer is not used)
for H3/M3+KF, the sound card name must be 'ak4613'
So #24572 was there to enable dunfell w/o KF, as you stated.
And #24760 reverts #24572, as we now have the Cogent layer as we used to before migration.
What you propose is to cancel #24760 and do the equivalent in meta-agl-bsp/meta-rcar-gen3-adas, to only enable the fix only when Cogent layer is pulled. I'm fine with that but this is a separate issue. Could we see that in a second step and in a separate jira issue?

Now you confuse me:
https://gerrit.automotivelinux.org/gerrit/c/AGL/meta-agl/+/24572 was to enable dunfell w/o KF:
--> state.rcarsound
So to enable the variants with the Kingfisher (aka [h3|m3]ulcb-kf in aglsetup),
https://gerrit.automotivelinux.org/gerrit/c/AGL/meta-agl/+/24760 will rename all boards but the ebisu .
--> state.ak4613
To me it makes no sense to put this (as a revert) into meta-agl-bsp/meta-rcar-gen3/recipes-bsp/alsa-state/alsa-state.bbappend but instead it should be in
meta-agl-bsp/meta-rcar-gen3*-adas*/recipes-bsp/alsa-state/alsa-state.bbappend
and thus just apply only whenever the cogent layer is enabled.
YES it would be better to fix the root cause, but do you really wanna dig through > 480 patches 
?
See: https://github.com/CogentEmbedded/meta-rcar/tree/dunfell-Yocto-v3.21.0/meta-rcar-gen3-adas/recipes-kernel/linux/linux-renesas
Answer is no, b/c we don't have the time to redo that over-and-over again. Just my 0,02€.
