I would be interested in this as well, some test framework for auto regression
checks would be great.

I think Mark would be at KS and can update if we can leverage something for
kselftest stuff being discussed there

I think ASoC has grown a lot with DPCM etc making it very dynamic atm. So
yes it will help to add more

yes, I think the current control names were too HDA specific. With DSP and
audio hub proliferation on SoCs/Codecs revisiting this would certainly be
great. Like how do I specify volume control for gain before a mixer, or gain
in capture BE which is different from the one on capture FE.

Configuration convergence:
>From the OS side, we have Desktop OSes relying on PA, Chrome using CRAS,
Android using flinger. With DSPs and tons of configuration it doesn't bode
well to have multiple configuration for same stuff for the sound cards. Can
we talk about unifying the configuration at least. Sure OSes will have their
own ways to use, but from ALSA can we standardize configurations which
can be reused across.

And lastly, our users :)
Ask from PA, Android, ChomesOS folks??
