(X)Ubuntu microphone mute/unmute script

The goal of this script was to have a simple script, binded with a shortcut which allows to mute/unmute all the microphones and to display a nice notification in the process. This is the simplest version working on xubuntu 14.04 with pulseaudio.

ACTION=1 #1 mute, 0 unmute
SCNT=$(pacmd list-sources | grep muted | wc -l)
MUTED=$(pacmd list-sources | grep muted | grep yes)
if [ $? == 0 ]; then
    notify-send -i microphone-sensitivity-medium "Microphone" "Unmutting $SCNT sources..."
    notify-send -i microphone-sensitivity-muted "Microphone" "Mutting $SCNT sources..."
#SRC=$(seq $SCNT)
SRC=$(pacmd list-sources | grep index | cut -d':' -f2 | tr -d ' ')
for i in $SRC; do
    #let s=$i-1
    pacmd set-source-mute $i $ACTION


xubuntu 14.04 – Trusty Tahr

There is not much to say about the new xubuntu 14.04 trusty tahr and this is a very very good thing. I had quite some work to do when installing 12.04 on my Tuxedo Laptop but with 14.04 I managed to setup almost everything in 2h on a friday night. Here is a list of just a few small hick-ups:

  • non blocking grub error while booting from my LVM root
Error: diskfilter writes are not supported.
Press any key to continue...

This is described and solved in this bug report (requires grub scripts modification)

  • very small trouble with Oracle XE 11
  • some problems with google-earth
len@tux:~$ google-earth 
./googleearth-bin: error while loading shared libraries: cannot open shared object file: No such file or directory

This is related to the missing i386 libraries but is well described in this post.

Update 05.05.2014: Problems with eclipse:

This is described here but the fix did not worked for me (I was in 3.7)
