Hi,
That information could be useful, we'll leave it. Heh, I did not even know there were that many backend packages, although my two Plasma 5 systems have good working audio. Thanks.
Just for the record, our kde-standard metapackage installs phonon4qt5-backend-vlc automatically so you will get the audio working out of the box.
A little bit off topic, but this is one of the top results in Google for installing KDE 5 in Debian. I've written up some instructions for installing Plasma 5 in Debian Sid using Siduction's repos: http://tombh.co.uk/plasma5-(kde5)-debian-sid/
Indeed the kdenext packages could be installed in debian because they don't depend on other stuff we have in the ther siduction repositories. Another story is upgrading from the current debian sid kde packages to kdenext, that wasn't actually tested (but I could add d-u test to my current routine), and I guess that's why you mentioned how to remove plasma and kde stuff from debian first.
Another thing: the instrucions in the first post are outaded, the current instructions (for siduction) are available in the KDE community wki:
https://community.kde.org/Plasma/InstallingNext#siductionThat being said, we have more stuff in siduction than kdenext, for instance towo is doing a splendid job providing us linux kernels more updated than debian, these kernels are also co-installable with debian's kernels, so if you have any problem with towo's you can always switch. You are very welcomed to try siduction and evaluate if you want to switch from debian sid. If you decide to stay with debian sid and keep using the kdenext packages you are also very welcomed to post in the forum if you find any issue.
I'm locking this topic now because it's outdated and may confuse users, we have a more updated thread here:
