I am trying to make a udev rule, for switching sound output, when HDMI is plugged and not plugged. My bash script is working if I manually call it from the terminal, and therefore the problem must lay on the udev rules.

So far I have been using the code giving on Archs wiki site:
udev and script code

Udev:

KERNEL=="card0", SUBSYSTEM=="drm", ACTION=="change", RUN+="/usr/local/bin/hdmi_sound_toggle.sh"

Script:

#!/bin/bash

export PATH=/usr/bin

USER_NAME=$USER

USER_ID=$(id -u "$USER_NAME")

CARD_PATH="/sys/class/drm/card0/"

AUDIO_OUTPUT="analog-surround-40"

PULSE_SERVER="unix:/run/user/"$USER_ID"/pulse/native"



for OUTPUT in $(cd "$CARD_PATH" && echo card*); do

  OUT_STATUS=$(<"$CARD_PATH"/"$OUTPUT"/status)

  if [[ $OUT_STATUS == connected ]]

  then

    echo $OUTPUT connected

    case "$OUTPUT" in

      "card0-HDMI-A-1")

        AUDIO_OUTPUT="hdmi-stereo" # Digital Stereo (HDMI 1)

     ;;

      "card0-HDMI-A-2")

        AUDIO_OUTPUT="hdmi-stereo-extra1" # Digital Stereo (HDMI 2)

     ;;

    *)

        AUDIO_OUTPUT="analog-stereo"

    ;;

    esac

  fi

done

echo selecting output $AUDIO_OUTPUT

exec  pactl --server "$PULSE_SERVER" set-card-profile 0 output:$AUDIO_OUTPUT+input:analog-stereo

#sudo -u "$USER_NAME" pactl --server "$PULSE_SERVER" set-card-profile 0 output:$AUDIO_OUTPUT+input:analog-stereo

---

I have already tryed

• Running the script in terminal, to see if it works, which it does.


• Checked if HDMI is detected with udevadm monitor, which it sometimes is, and sometimes not.
