How to change default volume for Linux Mint?

Question

I have Linux Mint (with KDE desktop, if it matters) installed on my notebook. Every time when I power it on the volume is set on 100 (maximum level). How can I change this value? Or maybe enable saving volume level at shutdown?

Answer 1

Changing Volume from CLI

From looking at this Unix Stack Exchange post it looks like there is the pactl command that can be used to control the volume, such as:

# Increase volume by 50%
pactl set-sink-volume 0 +50%

# Decrease volume by 50%
pactl set-sink-volume -- 0 -50%

You will need to identify the sink to change the volume for with pactl list short sinks.

Running Command at Boot Time

This command can be added to the crontab so that it is executed at boot time, to do this:

• Open crontab file for editing (this will use the $EDITOR or $VISUAL variable if set)

  crontab -e
  

• Add an entry similar to the following (this will take 50% from the volume level at boot time)

  @reboot        pactl set-sink-volume 0 -50%
