The IAMStreamSelect interface controls which logical streams are played and retrieves information about them. An example of logical stream selection is selection from a set of audio streams that encode different national languages. For example, the client might be able to choose from a set of logical audio streams that included English, German, and French.
In addition to the methods inherited from IUnknown, the IAMStreamSelect interface exposes the following methods.
| Method | Description |
| Count | Retrieves the number of available streams. |
| Enable | Enables or disables a given stream. |
| Info | Retrieves information about a given stream. |
