Ubuntu: Test Sounds Missing After Messing With Pulseaudio and JACK



Question:

So after installing JACK and using 'sudo usermod -a -G audio username' and restarted. This made JACK work however no program using pulseaudio (more or less everything) made any sound. I purge removed Pulseaudio, restarted, reinstalled it, restarted and finally the sound was working again. The only place sound won't come from is the test area in sound preferences.

I realise that performing a command I know little about was daft and that those test sounds aren't of very high importance, but I like things to run as intended. If anyone can help, it'd be very appreciated.

Thanks in advance.


Solution:1

When you uninstalled pulseaudio, other programs and libraries were removed as dependencies. To find out what they are (so you can reinstall them) look at the log.

The log is located here: /var/log/dpkg.log

Look for the line that contains "remove pulseaudio" (without the quotes) Above that line you will see what was removed as a dependency, here's what I found:

projectm-data  paprefs  libftgl2  libprojectm2  libprojectm-qt1  projectm-pulseaudio  libcanberra-pulse  indicator-sound  

You can install these items with the following command:

sudo apt-get install projectm-data paprefs libftgl2 libprojectm2 libprojectm-qt1 projectm-pulseaudio libcanberra-pulse indicator-sound  

The one causing your particular issue is libcanberra-pulse

indicator-sound is the one that shows a volume icon at the top in Unity
