I recently bought an Asus Vivobook S14 with a Realtek ALC294 chip (according to alsamixer) and the Intel Lunar Lake-M HD Audio controler (according to pwvucontrol).
When I try to play any sound, it goes silent once or twice per second and when I plug in my headphones with a jack cable there is no sound, instead I get a very loud cracking/popping repetitive sound through the headphones if I try to play something.
I am using Pipewire with Alsa as my audio config. Here are the packages I have installed

I have tried removing some of these packages with no result. I have tried changing the `default.clock.rate` and `default-clock-quantum` in /etc/pipewire/pipewire.conf to no avail. I have no idea what the problem may be.
I noticed that if I go to `alsamixer`, select the sound card `sof-hda-dsp` and unmute the Headphone option, magically the laptop speakers work! However, the headphones remain the same, so this is no permanent solution altough it may give someone more experienced a clue. I am not very well versed in linux, so any help/advice is well appreciated. Thank you
