* Interval [wMin=-12308, wMax=0] is not a multiple of wRes=426
This seems like a problem. Indeed (0 - -12308) = 12308 is not a multiple of 426.

Hi, from here:

The driver supports one single volume range only. If the Volume Control GET
RANGE request returns more than one range, then subsequent ranges will be
ignored.
With best regards,

Thanks Matthew,
For ACClockSource ranges, it allows length up to 258 bytes so I would expect
the get volume range to follow kind of the same structure as stated in the spec.
Here is part of the logs.

Subject: [wdmaudiodev] Re: UAC2 volume multiple range control
The OS send the volume range request one time on enumeration. I even tried to
use the audiocontrol interrupt endpoint to request OS to grab one more time. It
did come, but now the sound control now shows the 2nd range that I gave. The OS
does not seems to accept multiple volume ranges.
My device have hardware buttons to control volume which have its own range and
resolution. Currently I always use the audiocontrol interrupt endpoint to ask
the Os to snap to our device volume. Only recently found a bug which only
happen on MacOS, the current volume will keeps reducing due to the volume
correction on every start/stop audio playback stream. Therefore volume snapping
on our part introduce the bug, but then we can't synchronize the device volume
and the PC sound control volume if we remove the feature.

This sounds like something that has to be tested in detail on all relevant
operating systems. What is so special that you can’t use one range and work it
out in firmware?

I understand what is required to send back the feature unit volume range
request command from the host PC (Windows 10/MacOS). But the problem is the
host PC only allow 8 bytes of data length to be sent back for the volume range
command. Anyone have any idea how to implement this?
Interesting. I would expect it to make one request of 8 bytes, then make
another request based on the wNumSubRanges you returned. That's the usual
protocol for variable-length layouts. Do you not see the second request?
