I was listening to a recording of the Tonkin Mix from 94.7 FM when all
of a sudden I heard no more music from my computer's speakers rather
they were coming from another computer's speakers. After the user
logged out of the other system audio returned back to my computer. I
could also get the audio back by executing 'pulseaudio -k' in a
terminal. We were able to recreate this by having the other user log in
again and they received the sound.
I feel this is a security issue because I could have been listening to
something like fluffertrax or having a conversation using a telephony
application.
