For more information, see Device Roles in Windows Vista.įor a code example that implements the OnDefaultDeviceChanged method, see Device Events. Depending on how the OnDefaultDeviceChanged method responds to role changes, the behavior of an audio application developed to run in Windows Vista might change when run in a future version of Windows. In that case, if the user changes the assignment of only one or two device roles to a new rendering or capture device, the system will call the client's OnDefaultDeviceChanged method only once or twice (that is, one call per changed role). Polycom CX300 R2 is a Microsoft Certified USB Audio Device that is Simple and Easy to Use USB Audio Device Plug-and-play installation Microsoft Certified. In a future version of Windows, the user interface might enable the user to assign individual roles to different devices. Thus, when the user changes the default rendering or capture device, the system calls the client's OnDefaultDeviceChanged method three times-once for each of the three device roles. When the user changes the default rendering or capture device, the system assigns all three device roles (eConsole, eMultimedia, and eCommunications) to the new device. The user interface in Windows Vista enables the user to select a default audio device for rendering and a default audio device for capture. In Windows Vista, the MMDevice API supports device roles but the system-supplied user interface programs do not. The three input parameters specify the data-flow direction, device role, and endpoint ID string of the new default audio endpoint device. If the user has removed or disabled the default device for a particular role, and no other device is available to assume that role, then pwstrDefaultDevice is NULL. The string remains valid for the duration of the call. This parameter points to a null-terminated, wide-character string containing the endpoint ID. Depending on how many accessories are connected to your console or device.

Pointer to the endpoint ID string that identifies the audio endpoint device. Learn how to fix audio and connection issues with your Xbox Wireless Headset. This parameter is set to one of the following ERole enumeration values: The device role of the audio endpoint device. The data-flow direction for a capture device is eCapture. The data-flow direction for a rendering device is eRender. This parameter is set to one of the following EDataFlow enumeration values: The data-flow direction of the endpoint device. and subsequent rise in its share price, created three billionaires and an.

These properties include KSPROPERTY_SYSAUDIO_DEVICE_INTERFACE_NAME and KSPROPERTY_SYSAUDIO_DEVICE_FRIENDLY_NAME.Ī get-property request retrieves the device ID of the current (last opened) virtual audio device.The OnDefaultDeviceChanged method notifies the client that the default audio endpoint device for a particular device role has changed. MEDIA - Microsoft - High Definition Audio Device Drivers Download - Update. Under the Audio Device section, select your primary device from the drop-down menu. Some SysAudio properties allow the current device to be identified by a null device ID of -1 rather than by a valid device ID in the range 0 to n-1, where n is the number of available virtual audio devices. The last device to be opened is referred to as the current device. RemarksĪ KSPROPERTY_SYSAUDIO_DEVICE_INSTANCE set-property request opens the virtual audio device specified by the device ID contained in the property value. Otherwise, the request returns an appropriate error status code. Return ValueĪ KSPROPERTY_SYSAUDIO_DEVICE_INSTANCE property request returns STATUS_SUCCESS to indicate that it has completed successfully. If SysAudio enumerates n virtual audio devices (see KSPROPERTY_SYSAUDIO_DEVICE_COUNT), then valid device IDs range from 0 to n-1.

The property value (operation data) is of type ULONG and specifies the device ID of a virtual audio device. The KSPROPERTY_SYSAUDIO_DEVICE_INSTANCE property specifies the current instance of a virtual audio device.
