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
