The above packages are in (and only in) https://launchpad.net/~jon- hedgerows/+archive/ubuntu/get-iplayer. That ppa also uses other libav type packages. I use that ppa in order to use get_iplayer app as the BBC keep changing iPlayer re their servers for it.
I used y-ppa-manager (from https://launchpad.net/~webupd8team/+archive/ubuntu/y-ppa-manager) to find that out. I purged that ppa using y-ppa-manager and it showed that the relevant packages had been changed to different versions. I checked that it was purged with sudo ppa-purge https://launchpad.net/~jon- hedgerows/+archive/ubuntu/get-iplayer. That showed no package list for that ppa. I did the standard 'sudo apt-get update' & 'sudo apt-get upgrade' and everything Ok. I checked the version number for libavcodec- extra of that installed against the ppa's version and it had successfully done the reversion away from the ppa. In summary, now using the standard (rather than the ppa's) versions of the libav packages. However, still no sound for mp3 files using vlc. I haven't checked all the other possibilities e.g. playing CDs. Output from 'dpkg -l | grep libav > libav.txt' attached. ** Attachment added: "libav.txt" https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1755144/+attachment/5080107/+files/libav.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1755144 Title: No audio on vlc or videos sound or video files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1755144/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
