+# volume-helper.sh — Unified volume control script for Hyprland using pactl
+#
+# Purpose:
+# Many systems have multiple audio output devices (sinks), such as onboard
+# audio and an external device (e.g. M-Audio M-Track). This script adjusts the
+# volume of both:
+#
+#   - The default sink (`@DEFAULT_SINK@`)
+#   - A second sink (identified by partial name, e.g., "M-Track")
+#
+# Supports:
+#   - up       → Increase volume by 5% (defined by STEP, capped at MAX_VOLUME)
+#   - down     → Decrease volume by 5%
+#   - mute     → Mute all sinks
+#   - unmute   → Unmute all sinks
+#   - toggle   → Toggle mute state of all sinks
+#
+# Do NOT run this with sudo! pactl must run in your user session.
+#
+
+MAX_VOLUME=140
+STEP=5
