How to control Zoom's volume on its own, apart from the rest of your Mac

You can't give Zoom its own volume from the Mac's system controls — macOS has a single master output level, so the volume keys move Zoom, your music, your browser, and every alert together. Zoom's own Speaker slider looks like the fix, but it's tied to your output device and usually drags the whole system volume with it. The only reliable way to keep Zoom quieter (or louder) than everything else on your Mac is a per-app volume mixer that gives the Zoom process its own level. This guide covers the free options, exactly where they run out, and the fastest way to pin Zoom's level in one keystroke.

It comes up all day for anyone on calls: a Zoom meeting you're half-monitoring while music, a browser, and Slack keep going in the background. You want the call at a steady, comfortable level and everything else sitting under it — or the reverse when the call goes quiet and you want your music back. On Windows you'd open the Volume Mixer and drag the Zoom slider. On a Mac, the single master volume moves everything at once, so there's no system-level way to say "Zoom at 60%, everything else at 100%."

Why Zoom's own Speaker slider isn't the answer

Zoom does have a volume control — Settings > Audio > Speaker, with a Test button next to it. It's easy to assume this is a private, Zoom-only level. It usually isn't. That slider is linked to your Mac's selected output device, so on the built-in speakers or a normal pair of headphones, dragging it typically moves the system output volume — the same level the F-keys control. Turn Zoom "down" there and you can find your music dropped with it. On some external audio interfaces the slider is disabled entirely, because the device owns its own hardware level and macOS won't let Zoom override it.

This is a macOS behavior, not a Zoom bug — the app is only ever talking to one shared output. It's also why Zoom feels different from an app like Spotify or VLC, which each carry a genuinely internal slider that scales only their own playback. Zoom doesn't have that kind of independent level to give you, which is the whole reason this question keeps getting asked.

What actually controls incoming Zoom audio

One more source of confusion worth clearing up: Zoom's most famous shortcut, Command-Shift-A, mutes your microphone — it changes what other people hear, not what comes out of your speakers. The same goes for the mute button in the toolbar. There's no built-in Zoom hotkey that turns down or silences the call audio you're listening to. So if your goal is "make the call quieter without touching my music," none of Zoom's own controls get you there cleanly. You have to reach outside Zoom.

Option 1 — Lean on the other apps instead (free, partial)

Since Zoom can't give itself a separate level, the free move is to turn everything else down around it. Most media apps carry their own internal slider: Spotify in its now-playing bar, YouTube and other web players in the video, VLC in its window. Drop those and you effectively raise Zoom's relative loudness without moving the system volume.

It's a real workaround for a fixed setup, but it's backwards and it leaks. You're adjusting three apps to change one, the sliders all live in different places, and the moment an app with no slider joins the mix — a game, a system alert, a conferencing tool other than Zoom — you've got nothing to grab. And you still can't make the call quieter than your music; you can only make the music quieter than the call. If the call itself is the loud one, this approach can't help. It's the same wall you hit any time you try to lower one app without lowering everything on a Mac.

Option 2 — A per-app volume mixer (the real fix)

A per-app mixer sits at the macOS audio layer and gives every running app — Zoom included — its own level in one place. This is the Volume Mixer Apple never shipped. You set Zoom's channel to 60%, leave your music at 100%, and the balance holds until you decide to change it. Unlike Zoom's Speaker slider, this really is a per-app level: it lowers the Zoom process and nothing else. Tools that do this include Background Music (free, open source), SoundSource by Rogue Amoeba (paid, deep), and Fader (paid, keyboard-first).

All three set a true separate level for Zoom. Where they differ is how fast you can reach the control while a call is live — and that's what decides whether you actually ride the balance or just set it once and forget it.

Background Music is a genuinely good free option: if you're comfortable with an open-source utility and a menu-bar list, it will give Zoom its own level at no cost. SoundSource is the polished, feature-rich choice — per-app volume plus EQ and audio effects, $49 one-time. Fader's angle is narrower and faster: a separate Zoom level you can reach without lifting your hands off the keyboard.

Why the keyboard matters during a call

Mid-meeting, the speed of the control is the whole game. A menu-bar list means: move to the menu bar, click the icon, find the Zoom row, drag, dismiss — five actions while someone's mid-sentence. Zoom's own Settings slider is worse, and it's the wrong level anyway. The reason you want a separate Zoom level is that the balance keeps shifting: the call gets important, you bring it up; it goes quiet, you push your music back.

Fader's bet is that the fastest controller you own is already under your hands. You hit a toggle hotkey and the keyboard becomes a mixer — one letter column is Zoom, the next is your music — and you ride Zoom's level with key presses without ever leaving the call window. You can also bind a single per-app mute key to Zoom, so dropping the call to zero (finally, without touching your mic) is one keystroke. If balancing the call specifically against music is your setup, the companion guide on how to make Zoom quieter than Spotify on a Mac walks through that exact recipe.

A quick setup for back-to-back calls

If your day is mostly meetings, the setup that pays off is: give Zoom a fixed channel in the mixer, park it at a comfortable level, and bind a mute key to it. Then you're not fishing through Zoom's Settings or Zoom's toolbar when a call gets loud — you tap one key to drop it, tap again to bring it back, and your music and alerts never move. Set once, ride from the keyboard, and the "which slider was it again?" scramble goes away.

Bottom line

Zoom can't give itself a volume that's separate from the rest of your Mac — its Speaker slider is really the system output in disguise, and its mute shortcut only touches your mic. The free workaround is to quiet the other apps around it, which is fine for a fixed setup but breaks the moment the call itself is the loud one. For a Zoom level that's truly its own, and that you can move in a keystroke without leaving the call, a per-app mixer is the fix. Background Music does it for free; if reaching the control fast is what you care about, that's exactly what Fader is built for.
