go install github.com/daved/shound/cmd/shound
mkdir ~/.config/shound
curl -o ~/.config/shound/config.yaml https://raw.githubusercontent.com/daved/shound/main/cmd/shound/example.config.yaml
# add the following or equivalent to the shell rc file (e.g. ~/.bashrc)
type shound &>/dev/null && eval "$(shound export)"
shound -h # shows all top-level subcommands
shound -h theme # shows subcommands for the theme top-level subcommand
shound theme install github.com/daved/shound-star_trek
shound theme set github.com/daved/shound-star_trek
Then modify the config file (~/.config/shound/config.yaml) as preferred. The value that will most likely require a change is the command to use for playing audio. It may end up being something like aplay or paplay. Some modifications of the config file may require the shell to be restarted.
This readme was written up from memory, so my apologies if something is out of order. There's simply not a lot of time available for me to test this at the moment.
