Good question. Once you have downloaded the .deb files you can install them directly and they will replace the existing (newer) version you had installed. You shouldn't try uninstalling those packages because there are dependencies on them elsewhere in Ubuntu. Only change the versions that you have (which will automatically and atomically replace what's there at present).
To install a bunch of deb files run this command in a terminal: sudo dpkg -i *.deb or similar. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1755144 Title: No audio on vlc or videos sound or video files Status in pulseaudio package in Ubuntu: Incomplete Bug description: Up until a few weeks ago there was no problem with playing sound from mp3 files. I have a pair of usb speakers. Audio plays Ok on them for video clips using Chrome (e.g. from BBC website). Using vlc 2.2.2 (from Ubuntu repos), neither a CD nor DVD (video is Ok) nor mp3 file plays audio. mp3 files play Ok using Rhythmbox. I've also tried vlc 3.0 with no success. Interestingly, the standard Videos app (Totem?) also doesn't play sound on these speakers either of an mp4 file (downloaded from YouTube, though it plays Ok on YouTube website using Chrome) or a DVD. Clemenetine plays mp3 files Ok. I first reported this as bug 1752267 as I thought that the problem was with vlc. On that bug, it was suggested that the problem is with Pulseaudio. Just now, I've tried to play sound through my monitor's built in speakers connected by hdmi (though the monitor displays Ok) with no success even though the built-in speakers play sound using pavucontrol when testing is invoked.
