Stop Clicking Through Sound Settings — Switch Audio Devices and Per-App Volume From a Hotkey

If you’ve ever plugged in headphones and groaned
at the four-click trip through Windows’ sound settings, or watched one rogue Chrome tab blast over your
music, Volume Level Adjuster is for you. It’s a tiny AHK v2 tool that gives you a
per-app audio mixer and a one-click default-device switcher — plus CLI flags so you can wire it to a
hotkey or a scheduled task.

The Problem

Windows hides per-app volume controls behind menus that change every release.
SoundVolumeView is fine but it’s a black-box exe. If you live in AutoHotkey and want something
scriptable, transparent, and easy to bind to your own hotkeys — there hasn’t been a clean option. Until now.

What It Does

• Per-app session list — see every process making sound right now: name, PID, volume %, mute state, and which device it’s routed to.
• One-click default device switch — dropdown at the top flips the system default playback device instantly.
• Auto-refresh every 2 seconds while the window is open, so the list stays live as apps come and go.
• CLI flags for scripting from a hotkey, scheduler, or another tool.
• No external dependencies — Core Audio COM interfaces are wrapped inline in pure AHK v2.

CLI Examples

Why You’ll Like It

That last command is the killer one. Bind /SwitchDefault "Speakers"
"Headphones" to a single hotkey and you’ll never poke at the system tray again — one keystroke
flips audio between your two most-used devices. The same goes for a meeting hotkey that sets the default
to your USB headset, or a “movie mode” that swaps to your TV’s HDMI output.

Get It

Volume Level Adjuster is a one-time download — script source plus a compiled
exe so you can run it without AutoHotkey installed. Customize the hotkeys, extend the GUI, or just drop
the exe on a coworker’s machine.

Tired of clicking through four menus every time you plug in headphones? Grab it and bind one hotkey — done.
