How to turn down your game so you can hear Discord on Mac

When your game buries your squad on a Mac, the fix isn't touching Discord — it's turning the game down. Most games hide a master or effects slider in their audio settings; drop that and voice callouts rise back up in the mix while Discord stays exactly where it was. The snag is that plenty of Mac games ship no usable slider at all, and the ones that do bury it in a menu you have to pause and dig into. To duck the game against Discord in a keystroke, mid-match, you need a per-app mixer that puts both on one set of controls.

This is the flip side of the usual gaming complaint. Sometimes Discord is the loud one; often it's the other way round — the game's gunfire, music, and effects sit on top, and your friends' callouts drown underneath. Reaching for the Mac volume keys doesn't help, because macOS gives you a single master output that sits in front of every app. Turn it down and the game and Discord drop together, so you never change the balance between them. The real fix is to work one app at a time, and the app you want quieter here is the game.

Fastest fix: turn the game's own volume down

Most games carry a volume control of their own, and it only affects that game. Open the game's settings, find the audio or sound section, and pull down the master level — or, if it splits them out, the music and effects sliders while leaving dialogue where it is. The game gets quieter; Discord doesn't move, because Discord is a separate app with its own level. If your friends were getting buried, they come right back to the front of the mix.

The one downside is timing. That slider lives inside a settings screen you usually have to pause the game to reach, which is fine to set once before a session but useless in the middle of a firefight. If you know you always want the game a notch under voice chat, set it before you queue up and you're done.

When your Mac game has no volume slider

Not every game gives you one. Some ported titles, older releases, and lightweight indie games expose only a single on/off for sound, or nothing at all. When that's the case, there's no in-game way to hold the game under Discord — the game plays at whatever level it decides, and your only built-in lever is the master output, which drags Discord down with it. That's the wall the built-in route hits.

You also can't fix this from Discord's side without making things worse. Turning Discord's output up to compete just pushes voices toward clipping, and cranking the master to hear the game louder puts you back where you started. The clean answer is a real per-app volume on the game itself, whether or not the game bothered to include a slider.

Leave Discord alone — the point is to keep it loud

It's tempting to fiddle with Discord too, but resist it. The whole goal here is to keep your friends clear and present, so lowering Discord's output is the wrong direction. The only Discord tweak worth making is the opposite one: if a single teammate is too quiet, right-click their name in the voice channel and raise their personal slider — that boosts just them, for you only, and leaves everyone else alone. Beyond that, keep Discord where it is and let the game do the moving.

If your real problem is the reverse — Discord blaring over the game rather than under it — that's a different fix, and it's covered in how to lower Discord without turning down your game. Same tools, opposite direction.

Why the Mac volume keys can't help here

It's worth being clear about why this is annoying in the first place. macOS routes every app through one shared output, and the volume keys move that single level. There's no native panel that says "game at 60%, Discord at 100%." Windows has had a per-app Volume Mixer for years; macOS never shipped the equivalent. So the game arrives at its own loud level, Discord arrives at its own quieter one, and the only system control you have moves both of them at once. That gap is exactly why a whole category of Mac audio apps exists.

The keyboard-fast fix: a fader on the game, a fader on Discord

A per-app mixer sits at the audio layer and gives every running app its own level in one place — the panel Apple left out. Crucially, it works on whatever is producing sound, so it can set a game's volume even when the game has no slider of its own. Tools here include Background Music (free, open source), SoundSource by Rogue Amoeba (a deep menu-bar mixer, $49 one-time as of version 6), and Fader (paid, keyboard-first). They all set per-app volume; the difference you feel is how fast you can reach the control once the mix shifts.

Fader's whole bet is that the fastest controller you own is already under your hands. You hit a toggle hotkey, the keyboard becomes a mixer — one letter column is the game, the next is Discord — and you ride levels with keystrokes without ever leaving full-screen. Game creeping up over a callout? Tap it down two notches and keep playing; Discord never moves. Because it works at the OS audio layer, it handles the games and background apps that never gave you a slider to begin with.

If you'd rather not pay, Background Music genuinely does the job — it's a solid free per-app mixer, and for a balance you set once before a session it's plenty. What you trade is the reach: a menu-bar list you click into versus a keystroke from inside the game. For a mix you nudge constantly during a match, that reach is the difference between a mixer you actually use and one you forget is installed. If you also stream or capture your play, it's worth reading the full streamer's Mac audio setup before you buy anything.

Bottom line

When the game is drowning your squad on a Mac, turn the game down, not Discord — lower its own master or effects volume so voices come back to the front. That's free and it's the right first move. Where it runs out is games with no slider, and any moment you need to re-balance without pausing. macOS has no one place to ride the game against Discord, so a per-app mixer is the fix. If reaching the control in a keystroke, mid-match, is what you care about, that's exactly what Fader is built for.
