Dependent claims

A method for transmitting call audio data, applied to a first electronic device, wherein the first electronic device comprises a first pulse code modulation (PCM) device, a second PCM device, and a third PCM device, wherein the first PCM device, the second PCM device, and the third PCM device are configured to cache PCM audio data, and wherein the method comprises:

establishing a call with a peer electronic device through a modem in response to a call operation, wherein the first electronic device and a second electronic device are in a multi-screen collaboration mode;
receiving call audio downlink data from the peer electronic device;
storing the call audio downlink data in the first PCM device by:
opening the first PCM device and a collaboration call downlink path by opening a first PCM device file, wherein the collaboration call downlink path is configured to connect the first PCM device and the modem;
transmitting the call audio downlink data in the first PCM device to the second electronic device through the collaboration call downlink path;
receiving call audio uplink data from the second electronic device;
storing the call audio uplink data in the second PCM device by:
opening the second PCM device and a collaboration call uplink path by opening a second PCM device file, wherein the collaboration call uplink path is configured to connect the second PCM device and the modem;
transmitting the call audio uplink data in the second PCM device to the peer electronic device through the collaboration call uplink path;
and
storing the call audio uplink data and the call audio downlink data in the third PCM device in response to an incall record operation.
