Hi,

   sgtl5000 is the codec chip in my zynqMP project and the play is OK.The key register value is as following,

CHIP_DIG_POWER = 0x63

CHIP_SSS_CTRL = 0x10

CHIP_ANA_CTRL = 0x22

 

The record has noise when playing the same time, and has no voice when not playing.

I analyze the code of the chip(mxs,imx,tegra)。The mentioned chip all have "audio-routing" in the device tree.

Does the zynqMP(xilnx) need it?

Can anyone help me?
