This error usually means that pulseaudio isn't running.

VLC tried to use alsa instead of pulseaudio, but some other application
kept the sound card busy.

That sounds like you've removed pulseaudio. client.conf is shipped with
libpulse, which you clearly have installed, but /etc/pulse should also
contain daemon.conf, default.pa and system.pa, and those files come
with the main pulseaudio daemon package.
