Hi Takashi,

This platform booted with Ubuntu 24.04 with Pipewire audio server. So, it h=
as pop
noise with headphone. But it's normal with Pulseaudio server.
This patch was the workaround. Connect the headphones to DAC 0x2.
The popping sound will disappear.

This solution was approved by Dell.

Thanks.
Kailang
