I just changed my computer and installed guix thereon. I found that, curiously, my notification was not working. I spent the day debugging; the script itself ran the sound just fine. The permissions were legal. Finally I found a command that mentioned other earlier errors in my dunstrc file:
dunst -conf /home/ME/.config/dunst/dunstrc
WARNING: Setting notification_height in section global doesn't exist
WARNING: Setting startup_notification in section global doesn't exist
WARNING: Setting verbosity in section global doesn't exist
I learned that those warnings mean the setting SHOULD NOT exist, but it is (wrongly) there. Apparently that was stopping my configuration from being read. So, I commented out the misplaced settings:
# notification_height = 0 ## no more
# startup_notification = true ## no more
## verbosity = debug ## no more
There are newer locations for those settings, but I got up and running – with my audio script being read – by commenting those out.
