This should be an audio chipset-specific issue of the ALSA(Advanced Linux
Sound Architecture) sound system. There should be a command to toggle
mute/unmute the speakers but I cannot help you with that because I does not
use ALSA. I recommend you to try out the OSS4(Open Sound System v4) as an
alternative. It also comes with some benefits. You can read more here: , and
here: . Note, that the official (Trisquel's) documentation is a bit outdated
and inaccurate so here's my own one:
Open Terminal (press [Ctrl]+[Alt]+[T]), then follow:
To INSTALL OSS4 on Trisquel 4.0(+):
$ sudo su
$ apt-get update;apt-get install oss4-dkms oss4-gtk linux-headers-generic
linux-image-generic libc6-dev
$ dpkg-reconfigure linux-sound-base # Select OSS
$ xdg-open https://trisquel.info/wiki/installing-oss4-trisquel-40#toc4
$ FILE=/etc/pulse/default.pa;cp $FILE $FILE-old;gnome-text-editor $FILE #
Follow step 4
$ ossmix vmix0-src OFF # This will avoid low quality output.
$ reboot # This will RESTART your system!
To REMOVE OSS4:
$ sudo su
$ apt-get remove oss4*
$ FILE=/etc/pulse/default.pa;mv $FILE-old $FILE
$ dpkg-reconfigure linux-sound-base # Select ALSA
$ reboot # This will RESTART your system!
Optionally, follow steps 5-6:
$ xdg-open https://trisquel.info/en/wiki/installing-oss4-trisquel-40#toc5
If the problem persist, use this:
$ echo [Desktop Entry]>>~/Desktop/spkmute.desktop
$ echo Type=Application>>~/Desktop/spkmute.desktop
$ echo Name=Speaker Mute>>~/Desktop/spkmute.desktop
$ echo Exec=ossmix jack.int-speaker.mute TOGGLE>>~/Desktop/spkmute.desktop
$ echo Icon=xfce-sound>>~/Desktop/spkmute.desktop
$ echo >>~/Desktop/spkmute.desktop
$ chmod +x ~/Desktop/spkmute.desktop
This will create a handy shortcut on your desktop with which you can toggle
mute/unmute the internal laptop speakers. I also recommend you to put it on
your panel, so you does not need to switch to desktop and double-click on it
everytime you need it.
Also note, that these commands are originaly written for a shell script (made
for my own purposes) so the code may look a bit unclean for a 'Terminal' use.
Hope this help.
