heads up: timidity causes pulseaudio to not find sound cards

[Eric S Fraga <e.fraga@ucl.ac.uk>]

Hello all,

I recently did an 'apt update; apt upgrade' on my desktop which is
running testing (aka buster).  Doing so led to my losing sound through
any application that relies on pulseaudio, e.g. firefox.  I could still
use console based tools (e.g. mocp) to listen to music but pulseaudio
could not find my default built-in sound card, only the nvidia card
which provides sound through HDMI.  Unfortunately, not having any audio
device connected via HDMI, I could not hear anything.  I only have
speakers connected through the headphone jack.  (old skool)

Purging timidity from my system fixed the problem.  I did this based on
the advice from this web page:

https://bbs.archlinux.org/viewtopic.php?id=154002

although I am not entirely sure why this worked.  Halfway through the
purging operation, sound came back without even having to reboot or
restart any services.

Just a heads up in case somebody else loses sound all of a sudden.
