IMMDevice Interface

The IMMDevice interface encapsulates the generic features of a multimedia device resource. In the current implementation of the MMDevice API, the only type of device resource that an IMMDevice interface can represent is an audio endpoint devices.

A client can obtain an IMMDevice interface from one of the following methods:

• IMMDeviceCollection::Item
• IMMDeviceEnumerator::GetDefaultAudioEndpoint
• IMMDeviceEnumerator::GetDevice

For more information, see IMMDeviceCollection Interface.

After obtaining the IMMDevice interface of an audio endpoint device, a client can obtain an interface that encapsulates the endpoint-specific features of the device by calling the IMMDevice::QueryInterface method with parameter iid set to REFIID IID_IMMEndpoint. For more information, see IMMEndpoint Interface.

For code examples that use the IMMDevice interface, see the Rendering a Stream topic.
