when I try to play sounds from https://hpr.dogphilosophy.net/test/

I am doing this in my spare time outside of moving and some other items..
so I am not sure 'how fast' I can get to this. [My current guess is that
the Firefox requirement for pulseaudio in 78+ is looking for a different
version ABI that EL6 supports.]
