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?

Yup.
Why do you want to?
Is this a speaker or a microphone?

Hi,
We have wavecyclic miniport WDM audio driver. We would like to remove the
volume slider and mute control for our WDM device in Windows Sound and
Audio control panel.
I read this discussion on freelist:
//www.freelists.org/post/wdmaudiodev/SPAM-Bayesianalltestmode-Re-Disable-volume-control-or-Level-tab-at-MSVAD,1
Where Matthew had responded:
"If you remove the KSNODETYPE_VOLUME node then a software volume APO will be
put
in the capture path; there's always a slider on the Levels tab."
Does this mean that there is no way that we can remove volume slider and mute
control for our device?
I have already tried removing VOLUME and MUTE nodes from the nodes list that
is reported to Filter Descriptor.
Also I have removed volume and mute nodes from connection descriptor but it
does not remove volume and mute controls from levels tab.
Thanks,
Neetu
