The title says it all; at some point Ubuntu 18.04 stops playing sound and the only available sound device is "Dummy Output". Apart from rebooting (which fixes the issue) this command executed from the terminal fixes the issue: pulseaudio -k && sudo alsa force-reload Contributed by user Kim, source: https://superuser.com/questions/17312/restart-ubuntu-sound-processes-via-command-line

Installing the live image on a USB stick: bring some patience The first obstacle is that … Continue reading Ubuntu 16.04 LTS on the Acer Aspire E15
Having failed the 3rd repair attempt at the Thinkpad E540 [1] I gave up and bought the next best laptop from the nearby store that somehow is usable for programming. Behold: the Acter Inspire E15. 8GB RAM, i5, matte screen (1920x1080).

Update 25.03.2015: I strongly recommend against the Thinkpad Edge 540. There seems to be a systematic manufacturing problem with keyboards in many Edge models. Mine broke down a week after ordering, I installed a replacement keyboard which broke within two weeks of installing.

One of those on the Asus N56VB is handling of screen brightness which, for my taste, comes in too steep steps. Especially the minimum brightness is still too bright … Continue reading Smaller brightness steps with the Asus N56VB and Ubuntu
In ubuntu 12.04 VLC runs out of sync when pausing a video. First, when pausing the video, sound will continue playing for a couple of seconds.

Windows does that well and you'd expect that Ubuntu can do that as well, unfortunately it doesn't. Not without some scripting. So here we go: The … Continue reading Automatically regulating volume on a USB headset with Ubuntu
