One-liner to change the wireplumber's default sink using tofi (or rofi).
Uses jq to grab the audio sinks' names and ids from pw-dump and filters though your menu application of choice.
The final pipe uses ifne (from moreutils on arch) to only run the final wpctl command if the choice from tofi was non-empty (e.g., not cancelled or aborted).
This final line can also be used as a general recipe to run any command with input from tofi on the same condition that the result was non-empty.
