Solved it. I had to use pacmd set-default-sink rather than pactl set-card-profile. To be able to use it in a script, you must export PULSE_RUNTIME_PATH also. Create /usr/local/bin/hdmi_sound_toggle: #!/bin/sh HDMI_STATUS=`cat /sys/class/drm/card0/card0-HDMI-A-1/status` export PULSE_RUNTIME_PATH="/run/user/1000/pulse/" if [ $HDMI_STATUS = "connected" ] ...

Today, in my "Sound" ...
