Both waveOutSetVolume and the mixer APIs should be working on any recent builds
(with the caveat that Frank mentioned below: waveOutSetVolume using IDs didn't
work in all cases until recently).
If you attempt to set the capture volume using the mixer APIs, it won't work
(the API call should succeed, but the call will be ignored), the bug fix for
this didn't make the Feb CTP.
Please note that the wave and mixer volumes are plumbed to the per-stream
volume for render endpoints.

I have tried both handles and ids....But, I just realized that I am testing the
Mixer API implementation on build 5270 and not the latest build. I know that
both wave handles and device ids fail under the later version of Vista.
But, I am not sure about the mixer api under the lastest version of Vista. I'll
try it.

Are you using wave handles or wave IDs? Both will eventually work, but wave IDs
were not working until recent builds of Vista. You might not have a build with
this correction. I don't have the information at my fingertips regarding when
this was corrected.

MMSYSERR_NOTSUPPORTED
Hi,
I wrote a bunch of code to set/get the volume using the Mixer API and it works
under XP with my driver...but the same code with same driver does not work
under Vista.
So, I cannot set the volume using the Wave API or the Mixer API under Vista.
Yet, when I change the volume using the control panel under Vista, the messages
do get to my driver.

MMSYSERR_NOTSUPPORTED
Hi,
I wrote an audio driver that works under XP and Vista. It passes XP WHQL. Under
XP, when I call waveOutSetVolume() and waveOutGetVolume() everything works.
But, under Vista both those functions return MMSYSERR_NOT_SUPPORTED.
Does anybody know why this would be? Is that API not supported anymore? Do I
have to do something different in my driver under Vista to make this call work?
Under Vista the driver works very well...for example, when I change the volume
using MSN messenger that works. It is just the waveXxxGetVolume and
waveXxxSetVolume calls that fail.

MMSYSERR_NOTSUPPORTED
Hi,
I am receving MMSYSERR_NOTSUPPORTED when I call waveOutSetVolume() under Vista
(latest CTP version). Under XP, the same code returns no error.
Is this API no longer supported under Vista?
Is there a new API for controlling the volume, or do we have to use the
MixerAPI?
Thank you
