I've created a new user called 'mumble' using adduser, when logging a shell
into the user and running mumble, I get many permission errors (e.g.
PulseAudio server etc.). But, if I do this then mumble works fine and stores
settings etc:
(add new user 'mumble')
su mumble //login-as mumble, enter password
sudo mumble //gives elevated priveleges if mumble requires them
This is working so far, I'll fix the permissions so the user 'mumble' can run
mumble without sudo; at the weekend when these exams are gone.
P.S. I tried clearing every morsel of mumble (and ALL it's dependencies)
doing an apt-get remove/clean/purge, and looking for any .config files
remaining and no luck. This new user idea did work however.
