Without HDMI or Headphones audio not work

Support Sound
1

Hello to all,
I’ve recently intalled Manjaro KDE on my laptop hp 15-cb015nl and audio not work.
After I plugged in and ejected the headphones, everything was working again.
Now I connected my monitor via hdmi, and audio work on my monitor (and on my headphone), but now the audio without headphones or hdmi not work again.
I’m using 5.10.15-1 kernel, on alsamixer it’s all ok.
My exit is already on duplex.
cat /proc/asound/cards output:
