To our knowledge, labwc uses aamixer to handle volume keys. Most likely, aamixer (via PipeWire) controls the volume of the actual audio device sink (not the default sink), which causes the discrepancy in behavior. We recommend to specify the sink associated with the actual audio device in volumeSinkName (pactl list sinks).

You should change the commands triggered by XF86_AudioLowerVolume, XF86_AudioRaiseVolume and XF86_AudioMute in the $HOME/.config/labwc/rc.xml file to pactl (e. g. pactl set-sink-volume surround51_to_41 -5%).

Since pactl allows you to raise the volume above 100%, you can use a simple bash script that will limit the volume level and be triggered when pressing the aforementioned keys:

volume.sh

Code: Select all

#!/bin/bash

SINK="surround51_to_41"
ACTION=$1
STEP=5

case $ACTION in
    up)
        CURRENT_VOL=$(pactl get-sink-volume "$SINK" | grep -Po '\d+(?=%)' | head -n 1)
        
        if [ $((CURRENT_VOL + STEP)) -gt 100 ]; then
            pactl set-sink-volume "$SINK" 100%
        else
            pactl set-sink-volume "$SINK" +${STEP}%
        fi
        ;;
    down)
        pactl set-sink-volume "$SINK" -${STEP}%
        ;;
    mute)
        pactl set-sink-mute "$SINK" toggle
        ;;
    *)
        exit 1
        ;;
esac

then

Code: Select all

/home/pi/volume.sh up
/home/pi/volume.sh down
/home/pi/volume.sh mute

For the volume level changes from pactl to be visible in Hudiy, you need to modify the volume of the sink that is specified in volumeSinkName (to match the name of the sink controlled via pactl) - https://github.com/wiboma/hudiy/blob/ma ... n.md#sound
