@kRHYME7 after merge do include this sudo systemctl enable --now swayosd-libinput-backend.service. I couldnot find a file where I should add this

[TheyCallMeSecond]

it works fine but :

this should add to hyprland.conf, not keybindings.conf :

exec-once = swayosd-server

microphone mute botton should add too :

bind= , XF86AudioMicMute, exec, swayosd-client --input-volume mute-toggle # toggle microphone mute

pulseaudio.jsonc file in waybar modules should edit to this too :

`
"pulseaudio": {
"format": "{icon} {volume}",
"rotate": ${r_deg},
"format-muted": "婢",
"on-click": "pavucontrol -t 3",
"on-click-right": "volumecontrol.sh -s ''",
"on-click-middle": "swayosd-client --output-volume mute-toggle",
"on-scroll-up": "swayosd-client --output-volume raise",
"on-scroll-down": "swayosd-client --output-volume lower",
"tooltip-format": "{icon} {desc} // {volume}%",
"scroll-step": 5,
"format-icons": {
"headphone": "",
"hands-free": "",
"headset": "",
"phone": "",
"portable": "",
"car": "",
"default": ["", "", ""]
}
},

"pulseaudio#microphone": {
"format": "{format_source}",
"rotate": ${r_deg},
"format-source": "",
"format-source-muted": "",
"on-click": "pavucontrol -t 4",
"on-click-middle": "swayosd-client --input-volume mute-toggle",
"on-scroll-up": "swayosd-client --input-volume raise",
"on-scroll-down": "swayosd-client --input-volume lower",
"tooltip-format": "{format_source} {source_desc} // {source_volume}%",
"scroll-step": 5
},

`

we can edit backlight.jsonc file too:

`
"backlight": {
"device": "intel_backlight",
"rotate": ${r_deg},
"format": "{icon} {percent}%",
"format-icons": ["", "", "", "", "", "", "", "", ""],
"on-scroll-up": "swayosd-client --brightness raise",
"on-scroll-down": "swayosd-client --brightness lower",
"min-length": 6
},

`
