Audio doesn't work (LG All in One)

Hey, guys. I installed Arch Linux recently and my audio doesn't work properly. When I start without a headset, the sound works very well, but it stops working when I turn on the headset, working only as long as I hold the volume up button. I tried PulseAudio and ALSA wiki's solutions, but without success. What can I do?

PC info:

DE: Gnome
Operating System: Arch Linux
          Kernel: Linux 5.11.13-zen1-1-zen
    Architecture: x86-64
 Hardware Vendor: LG Electronics
