TAS5719 power on fail

Other Parts Discussed in Thread: TAS5719

Dear Sir,

We have a problem when using TAS5719 .

When power on and send reset / PND and I2C command. Speaker is no output.

If we short PDN to GND and release it to 3.3V. Output is OK!

Can you give me a suggestion and thanks in advance !

Attach waveform as below:

Pink: 3.3VDD

Green: PDN (Delay by RC)

Yellow: RESET(Delay by RC)
