No sound on wake, Dummy Output always takes over. 'pulseaudio -k' the fix
It be caused by a new kernel introduced in 19.10 like this case:
- Lagging after update to 19.10 from 19.04
If not then you can use this script /etc/systemd/system-sleep/reloadpulse
:
#!/bin/sh
# NAME: reloadpulse
# PATH: /lib/systemd/system-sleep
# CALL: Called from SystemD automatically
# DESC: PulseAudo 8 sets sound to dummy ouput when going to sleep.
# This script kills and reloads pulse audio.
# DATE: November 25, 2019.

case $1/$2 in
pre/*)
echo "$0: Going to $2..."
;;
post/*)
echo "$0: Waking up from $2..."
pulseaudio -k
;;
esac
Mark the script executable with chmod a+x /etc/systemd/system-sleep/reloadpulse
After updates deactivate it with chmod a-x /etc/systemd/system-sleep/reloadpulse
Then if the update didn't fix the problem make it executable again.
You need to reboot for changes to take effect.
I have a similar problem with Ubuntu 20.04.
This command solved the problem: pulseaudio --start
