I2S Audio Signal Timing and Clocking Errors

Confirm this symptom by observing if the audio output is intermittent, contains noise, or fails entirely when the sample rate is changed. Check if the Master Clock (MCLK), Bit Clock (BCLK), and Word Select (WS) signals are synchronized. If the timing frequencies between the source and receiver do not match or are unstable, the system will fail to decode the audio stream.
