Hello, NXP

 

I have a custom board with imx6q and sgtl5000, but when the machine get into suspend or wake up or shutdown, the speaker had a "pop" noise. I had tried this: setting the DAC_MUTE_LEFT and DAC_MUTE_RIGHT bit in suspend function, and clear them in resume function, but it didn't works. Any advices? Thanks.

 

Best Regards,

bo xu
