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.

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.

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
