You might have noticed that , by
default, the volume is muted on system startup in Kali Linux – this
is more annoying then helpful sometimes. If you want to get rid of
adjusting your volume every time your system boots-up, here's how you
can fix this.
First, install alsa utils: open a console window (for windows users it's the older brother of "command prompt") and type:
apt-get install alsa-utils -y
Once installed, type in the same
console window:
alsamixer
You'll see a screen like
the one below:
Set your volume as high as you like by using the up or down directional keys.
Press F6, and from the list of
available sound-cards choose the default card you have installed on your
system – in my case it's the HDA Intel.
By using the directional keys (up-down-left-right arrows), move to the
Auto-Mute menu.
Set it from the default “Enabled”
to "Disabled". Press “Esc” to exit the alsamixer menu, reboot Kali
and afterwards you'll notice that the system volume will retain it's volume control, no more
“default mute at start-up”.
