I configured my RPI3 for Network Audio Receiving via PulseAudio according to the wiki and everything works great.
Additionally, I set volume to 50%: pactl set-sink-volume alsa_output.0.stereo-fallback 50%
However, after the system restarts the volume resets back to 100% which nearly killed my dog. I tried adding the pactl command into /storage/.config/autostart.sh but it has no effect.
How can I set the volume to 50% by default?
