ALSA: hda/realtek - Fixed Headphone noise issue for Dell QCM1255

Browse Source 
This platform booted with Ubuntu 24.04 with Pipewire audio server. So,
it has 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.
