Hello
Im struggling with disabling auto-mute during kde startup
kde has a lovely startup sound and i want to hear it on every boot 
I know that arch wiki has 3 different ways achieving that but in my case nothing works so far , during every boot pulseaudio is muted
on alsamixer the auto-mute is absent its not there so i get an error that i cant find auto-mute option to disable
amixer --card=0 sset ‘Auto-Mute Mode’ Disabled
amixer: Unable to find simple control ‘Auto-Mute Mode’,0
anyhelp?
It’s not an auto-mute. Startup sound is effectively broken in the latest Plasma releases. Manjaro is not the only distribution affected by this, and the problem is known to the upstream KDE developers. 
startup sound will be something beautiful to have,
but its not about that , kde starts muted i have to manually unmute it every time, and archwiki doesnt helped me so far
Try to unmute it using alsamixer and then store the settings with sudo alsactl store
I have this same problem. Using the tricks on this page do not help. Using alsasctl store does not help.
This started happening several months back after a Manjaro patch. Was working fine for years prior. Every time I boot up, I have to unmute.
I tried deleting the pulse directory under my user account and that didn’t help either. It recreates it, but things are still muted.
I had the same issue on one of my computers, and someone suggested this, and it worked! See it that helps.
Disabling auto mute:
systemctl --user mask pipewire.socket --now
systemctl --user disable pipewire.service --now
Thanks, but this did not work. Also tried disabling locally as well as masking the pipewire.socket globally. I am guessing pipewire is not the cause.
Do you have "PulseAudio Volume Control (Pavucontrol) 1:4.0-2 " installed? I installed this as well when I was having the same issue.
Tried installing that too now, but no go. Muted on startup. It is not a showstopper, just annoying, especially when it was originally working when it was working at one time.
I just noticed that it defaults to muted every time I change the output controller from stereo to quadrophonic… So seems to mute itself every time the audio restarts.
