The analog volume/pan controls control a hardware amplifier, right?
Could the capabilities and state of that amplifier be exposed via the Kernel
Streaming properties, so the analog controls and the Windows controls affect
the same setting?

Thanks Frank and Tim... I really appreciate it. The audio device is a high-end
DAC which has analog volume/pan controls so the customer wants to make sure the
volume is always 100% digitally.
So I am working on a solution where driver publishes a very small range for
Volume control. For Mute, driver will ignore the requests from OS.

I should also mention- it's reasonable that you or your customer might be
hesitant to reveal product details on a public mailing list. In that case, feel
free to contact me or Matthew directly if you wish.
Also, the work-around that Tim Roberts described may be reasonable, again
depending on your reasons for not wanting a volume control. Your driver can
express a volume control that has a very small range and effectively ignore the
volume change requests from the OS. That doesn't stop the UI from showing of
course. But without knowing more about your problem, we don't know if that
matters.

Sure. It's not "important" and it doesn't change the answer to the specific
question, but it may allow us to suggest alternative solutions, and allows us
to understand the use case and scenario more deeply so that we can consider
changes in a future update.

May I know why is it important to know the details of their requirement? Does
it change the answer to my question?

OK... so... why do they want to?
