Abstract: An audio control method, a system, and device, the method including displaying, by a first device, in response to a first user operation, a candidate device list, obtaining, in response the user selecting a second device from the candidate device list, an audio capability parameter of the second device indicating a hardware capability and a software capability for playing audio, determining a first audio play policy based on the audio capability parameter of the second device, obtaining second audio data by the first device by performing first processing on first audio data from a first audio application according to the first audio play policy, and sending, by the first device, the second audio data to the second device, so that second device plays the second audio data or processes the second audio data and plays processed second audio data.

Abstract: A first audio timestamp of first audio is corrected based on a first latency corresponding to the first audio, to correct a correspondence between the first audio timestamp, the first audio, and a first image. In this way, a stored correspondence between the first image and the first audio is consistent with a correspondence between a picture corresponding to the first image and a sound corresponding to the first audio, thereby implementing audio and image synchronization.
