It be caused by a new kernel introduced in 19.10 like this case:
If not then you can use this script
#!/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. # NOTE: Written for ask ubuntu question: # https://askubuntu.com/questions/1191649/why-no-sound-on-wake-dummy-output-takes-over-pulseaudio-k-the-fix 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.
