[Bruce213]

hi i use adf play music demo as a network player，the pipeline as follow： RAW_WRITE --> DECODER--> I2S_STREAM_WRITE Some audio files have great playback delay, but the log shows that the i2S_write interface is called at the beginning, but after writing a lot of data to the i2S, the sound starts, but some audio files can play very quickly。

pls give me some help thanks in advance.

Hi @Bruce213

Generally speaking, after the audio data is written to i2s, there will be sound.

Could you check whether the audio data written is muted data?
