Audio-Output Device

An application can use the IVTxtAttributes::DeviceSet member function to set the audio-output device for a site. To change a device, an application must specify the device identifier of the new device. You can use the waveOutGetNumDevs and waveOutGetDevCaps multimedia functions to obtain the identifiers of the available audio-output devices in the system. The IVTxtAttributes::DeviceGet member function retrieves the device identifier of the current audio-output device for the site.
