+# This script toggles state between a few of my audio cables:
+#  combine sink -> default_output | hyperx_output
+#  clementine sink -> combine sink | default_output
+# The script also outputs a symbol indicating which configuration is active.
+# Usecase: My USB-C headset is a different sink than the one in the laptop; sometimes I want to have audio over the headset, sometimes through the laptop.
