The invention discloses a device and a method for improving the stability of a built-in audio bus slave of an integrated circuit. The device comprises a frame synchronization module, a bit counter, an error frame detection module, a shift register, a data control module and a received/sent data caching module. Wherein the frame synchronization module receives a clock signal and left and right sound channel signals sent by a host, and sends a frame synchronization signal to the bit counter; the bit counter receives a clock signal sent by the host and a frame synchronization signal sent by the frame synchronization module, and sends counting data to the error frame detection module and the data control module; the error frame detection module receives left and right sound channel signals sent by the host and counting data sent by the bit counter, and sends frame error signals to the outside. According to the method, the bit counter is reset through the frame synchronization signal, so that ...
