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
