The Acer Swift SF314-42 laptop is using Realtek ALC255 codec. Add a quirk so microphone in a headset connected via the right-hand side jack is usable.

Acer Swift SF314-42 laptop is using AMD Ryzen SoC audio with Realtek ALC255 codec. The are three ALSA cards: HDMI audio, AMD ACP card, and AMD HDA card. There is an internal stereo microphone connected to the ACP card, and a mini-jack connected to the Realtek codec. There are no LEDs.
I'd like to be able to use a mic+headphones headset. Unfortunately, out of the box ALSA does not correctly detect the microphone input of the Realtek codec. The suggested patch fixes that, though I cannot be sure it's 100% correct.
With the patch, the experience is unfortunately still not ideal. I have noticed a couple of issues:
1) at high enough gain, recording the microphone is picking up what is being played via the headphones; maybe it's supposed to be like that, but it surprised me;
2) there is a very noticeable "pop" when plugging the headset in/out, accompanied by
pcieport 0000:00:08.1: PME: Spurious native interrupt! pcieport 0000:00:08.1: PME: Spurious native interrupt!
in dmesg. I'd appreciate info and any help about this issue.
Thanks. Alexander
