Exposing multi-mode audio device as a single coherent audio device |
摘要 |
The driving of an audio device that supports two or more audio modes is accomplished by associating a first physical device object of an audio device with a first device identifier, the first physical device object representing a first audio mode enumerated by a bus enumerator; associating a second physical device object of an audio device with a second device identifier, the second physical device object representing a second audio mode enumerated by the bus enumerator; and if the first device identifier matches the second device identifier, enabling a coupled kernel streaming audio interface compatible with both the first physical device object and the second physical device object. |
