Audio muted on login by default

Audio Server: PipeWire with WirePlumber
Hardware: Tiger Lake-LP Smart Sound Technology
Driver: sof-hda-dsp
DE: KDE Plasma with Wayland

alsamixer shows MM on Headphone/Speaker (sof-hda-dsp) by default whenever I log in Arch

Things that I've tried to fix this:
- Unmuting audios using alsamixer then save alsa config (sudo alsactl store): Didn't work
- Resetting user configurations in ~/.config/pipewire and ~/.local/state/pipewire: Didn't work
- amixer scripting by creating a systemd user service to run amixer sset 'Headphone' unmute and amixer sset 'Speaker' unmute: Didn't work
- wpctl Scripting:
    - Attempt 1: wpctl set-mute @DEFAULT_AUDIO_SINK@ 0: Didn't work
    - Attempt 2:  Found my correct sink ID is 52 using wpctl status, then hanged the service to wpctl set-mute 52 0: Didn't work

Please help

Re: Audio muted on login by default

"by default" means you still have manual control over it afterwards? Or can you not unmute the sound at all?
Plasma might "restore" it from a bogus value w/ the session or when loading the volume indicator widget or so - have you checked whether there's some fixed value in systemsettings or so?

Ugly brute force solution: use https://wiki.archlinux.org/title/KDE#Autostart and schedule "(sleep 30; foo)&" a job to fix the state.
