Thanks, I missed that the bash-completion package is from extra - I'll 
update the README

Which pulseaudio version? The most recent 7.0 uses the 
/usr/share/bash-completion/completions directory, as does the 
bash-completion package itself (not /etc/bash_completion.d).

You're right that the directory (either 
/usr/share/bash-completion/completions or /etc/bash_completion.d) is 
created by 'make install' and a pulseaudio script is installed there. 
However the symlinks to that pulseaudio completion script are generated 
separately, using a different, flawed, method (see below) to determine 
where to generate them.

I think the missing bash-completion package remains the cause. If you 
look at the pulseaudio top level Makefile after the configure stage is 
done, you'll find:

install-bashcompletion-aliases:
         $(LN_S) -f pulseaudio $(DESTDIR)$(bashcompletiondir)/pactl
         $(LN_S) -f pulseaudio $(DESTDIR)$(bashcompletiondir)/pacmd
         $(LN_S) -f pulseaudio $(DESTDIR)$(bashcompletiondir)/pasuspender
         $(LN_S) -f pulseaudio $(DESTDIR)$(bashcompletiondir)/padsp
         $(LN_S) -f pulseaudio $(DESTDIR)$(bashcompletiondir)/pacat
         $(LN_S) -f pulseaudio $(DESTDIR)$(bashcompletiondir)/paplay
         $(LN_S) -f pulseaudio $(DESTDIR)$(bashcompletiondir)/parec
         $(LN_S) -f pulseaudio $(DESTDIR)$(bashcompletiondir)/parecord

Since $(bashcompletiondir) is empty if the bash-completion package isn't 
found, this install target generates the useless links described by the 
OP. The bash-completion package is considered found by the configure 
stage if it can find the bash-completion.pc file, part of the 
bash-completion package. Only then can the bashcompletiondir variable be 
set to something reasonable (non-empty at least).
