Amarok not playing after package updates - Fixed

I had exactly the same problem described by Jonb62 in the thread Amarok no longer play MPEG-4 AAC-strem. After accepting a bunch of package updates (codecs etc) Amarok lo longer responded to the play button for any file types. I found that I had the Packman repository sourced from 3 different packages so i disabled 2 of them. Then I followed the advice from wolfi323 specifically:

sudo zypper dup --from 'Packman Repository'

Finally after deleting the file

~/.cache/gstreamer-1.0/registry.x86_64.bin

the problem was solved. Amarok now plays again. Thanks to wolfi323 & Jonb62 for paving the way.lol!
