Hi Clements,
thanks for your reply.

The AK4528 ADCs indeed have no adjustable volume: http://www.asahi-kasei.co.jp/akm/en/product/ak4528/ak4528.html
Nevertheless I'm confused why other people reported similar problems where their ADC sliders were present and at some point (newer ALSA version) disappeared.
It's actually a fix of bogus controls. As Clemens mentioned, AK4528 has no ADC volume control in the hardware level. But the earlier driver provided the register access even though they didn't do anything correct.
I wonder if older ALSA version shows the ADC sliders by accident and it was corrected in later ALSA versions or if newer ALSA version have a bug... But I read in the post above that ADC adjustment works for some time with his 2496.
It must be a placebo.
Or exists some Audiophile cards were ADC adjustment is possible and some were not (different board revisions)?
That's also possible :)
