TAS5825M: Double SPK scheme.When no audio data is input and Automatic mute state, there is a idle noise in the speaker.There is also noise in playing music.

Part Number: TAS5825M

Description of test phenomena:

1、SDIN pin has no signal input.

2、LRCLK and SCLK signal input is normal.VR_DIG voltage 1.496V,GVDD voltage 5.10V,AVDD voltage 5.18V.The ripple was less than 12mV.

3、The impedance of SPK is 8 ohm.PVDD voltage 24V.

4、Adjusting gain has no effect on idle noise.
