There is no sound what so ever from the speakers and testing sound from the GUI doesn't work even when the normal sound works. The crashes seem to happen after I restart the computer or when I wake it up from standby. Solving the problem may take more iterations of the following procedures: 1) sudo alsa reload or 2) sudo apt-get remove --purge alsa-base pulseaudio sudo apt-get install alsa-base pulseaudio sudo alsa force-reload The methods for getting back sound have been taken from here: http://itsfoss.com/fix-sound-ubuntu-1304-quick-tip/ The problem is that this appears to happen randomly when I start my computer, so doing the before-mentioned steps is not really that fun.
