Hi community,


I have a question about i.MX6DQ Yocto BSP.

Pop noise is occurred when start video playback and finish playback if the video and audio is output to HDMI display.









1. Set bootargs "video=mxcfb0:dev=hdmi,1920x1080@60,bpp=32" to use HDMI display.

2. Boot L3.10.17_1.0.0-ga BSP.

3. Play a video with following command.

gplay test.mp4

4. Pop noise is output from HDMI display.




Could you let me know how to prevent this pop noise?
