1. Duplicate problem step:

   step 1: Inserted the camera module (camera ov5640_mipi driver: clock rate:24 MHZ)

   step 2: Plug in your headphones (sgtl5000-audio driver: clock rate:16 MHZ)

   step 3: Boot the device

   step 4: Playback video (1920*1080; audio rare: 44kHz; bitrate:192kbps)

   step 5: It will be occurred audio and video fast forward problem

2. If I do step 2~5 (Doesn't insert the camera module), It's work fine.

3. Do you have any suggestions to help me solve this problem?

4. I find that Audio clock [AUDIO_CLK (GPIO_0)] and camera mclock [CSI_MCLK (CSI0_MCLK)] share the same source.

    Can I separate Audio clock and camera mclock to use? If yes, How do I do?

 

Thank you.
