[pulseaudio-discuss] nearly solved pulseaudio configuration

[Jude DaShiell]

I found out running:
sudo -H lsof /dev/snd/pcm*
That espeakup appears twice in the table and that's the screen reader in 
use so espeakup is using the sound card directly.  Before this I had 
also changed default.pa so only the default-sink would be used and 
manual sink changes on reboot would have no effect.
