Abstract: A playback synchronization method and device and a USB sound card are disclosed. In the technical solutions according to the present disclosure, the number of writes for writing data into the audio data buffer by the write pointer of the master device and the number of reads for reading data from the audio data buffer by the read pointer of the slave device are acquired, and it is determined whether the data transmission of the master and slave devices is synchronized or not by judging the magnitude relationship between the number of writes and the number of reads. If it is not synchronized, the position of the read pointer is adjusted so that the write pointer and the read pointer are synchronized again, i.e., the write data and the read data are synchronized again. Thus, the problem that the clocks of the master and slave devices are relatively independent and the data transmission is not synchronized due to the clock deviation is solved.
