# 1. Confirm PipeWire sees speakers and volume is zero
wpctl status | grep -A5 Sinks
# → Speaker [vol: 0.00] — hardware works, volume zeroed

# 2. Manually set volume and test
wpctl set-volume @DEFAULT_AUDIO_SINK@ 50%
pw-play /usr/share/sounds/freedesktop/stereo/bell.oga
# → Sound plays — driver and sink are fine

# 3. Check what the keybind calls
grep 'XF86Audio' ~/.config/hypr/hyprland.conf
# → pamixer — not installed

# 4. Verify pamixer is missing
command -v pamixer
# → (nothing) — silent failure confirmed

# Before (pamixer — fails silently if not installed)

#!/usr/bin/env bash
# fix-hyprland-volume-keys.sh — Replace pamixer binds with wpctl (PipeWire-native)
#
# WHY: Hyprland volume/mute keys silently fail when pamixer is not installed.
#      wpctl ships with PipeWire — no extra package needed.
#
# WHAT THIS DOES:
#   1. Backs up hyprland.conf
#   2. Replaces 4 pamixer keybinds with wpctl equivalents (via awk)
#   3. Shows before/after diff
#
# USAGE: bash fix-hyprland-volume-keys.sh
#        Then reload Hyprland: hyprctl reload
