Comment 64 for bug 829051

@eschoeller: what link have you created?

I tried but didn't work:
sudo ln -sv '/usr/lib/pulse-15.0+dfsg1' /usr/lib/pulse-13.99.1

I have Ubuntu 21.10 and:

$find /usr/lib -maxdepth 1 -name "pulse-*" -type d -not -type l
/usr/lib/pulse-15.0+dfsg1

$strings $(type -P paprefs) | grep -i pulse
libpulse.so.0
PULSE_0
