Abstract
An optimized method for supporting simultaneously multipath Bluetooth audio application in a system includes said system establishes Bluetooth audio connections with a plurality of remote Bluetooth device simultaneously said system selects or adds dedicated Bluetooth soundcard audio device for each Bluetooth audio connection the data of each Bluetooth audio connection makes interaction with Bluetooth audio application in the system via respective dedicated Bluetooth sound card thus supporting multipath Bluetooth audio application simultaneously is realized in the system. Said system configures the sampling frequency and the sound channel mode of the Bluetooth soundcard audio device based on the format of the Bluetooth audio connection, in order to match the sampling frequency and the sound channel mode of audio data of the Bluetooth audio connection and reduce audio data format conversion. When said system exists a plurality of sound card audio devices only one of the sound card audio devices can become default sound card audio device usually the system sets automatically system default sound card audio device and notify correlative Bluetooth audio application. Said system also can notify correlative Bluetooth audio application that corresponding soundcard audio device hand been all set after said Bluetooth audio connections are established successfully so that multiple sound card are transparent for users.
