I finded a bug in a customer board for Android pad products. Using Android music App play a media file such as mp3. Audio has “pop” noise after pausing audio playback about 2~3.

The root cause if Android media player output some 0 data after pausing, so I2S data pin set to low. And then IOMUX pull up data pin (default I2S data pin is pulled up). So we can hear a pop noise. Fix the bug by pull down I2S data pin defaultly.
