Hi You can call waveOutMessage function. waveOutMessage((HWAVEOUT)WAVE_MAPPER, DRVM_MAPPER_PREFERRED_SET, id, 0); DRVM_MAPPER_PREFERRED_SET is defined in old mmddk.h. Simply enum waveOut devices, find id and call this function. I tested this on 2000 and XP. Of course this will be working after mmsystem is loaded.

Now there's a problem because Windows tries to play its sounds through my lines (device is used by TAPI). I can't set soundcard as preferred audio device with sound control panel - there are only 10 positions. So, how can I set preferred playback device (manually, with code or registry modifications) ??? It has to work for W2k and XP. best regards Konrad ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.de/ -- No virus found in this incoming message.
