Increase Sound level

Is it possible to set the default sound level more than 100% ?Every time after booting i have to manually increase the sound level from the sound settings which is a bit irritating. I am using Ubuntu 13.04.

Solution 1:

Using the following command in terminal, you can set sound level as you wish:

pactl -- set-sink-volume 0 150%

In this case we have set the volume of the sink #0 to 150%.

Now, if you want to set this setting as default at startup, add the above command in /etc/rc.local file. You can use sudo -H gedit /etc/rc.local to open an edit this file:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

pactl -- set-sink-volume 0 150%

exit 0

Solution 2:

in Ubuntu 20.04 LTS, you can simply open Settings and after that search for "sound" or just click on the Sound tab on the left side of the Settings panel. After that press "Over-Amplification" and change your max sound volume to more than 100% (more details on the screenshot below)
