Discord call problems usually come from one of three places: your internet connection, Discord's permission settings, or a conflict with your audio device

When Discord can't connect to a call, the app either can't reach Discord's servers, can't use your microphone or speakers, or is blocked by Windows or macOS settings. Most of the time you can fix this yourself by checking your internet, restarting the app, and making sure Discord has permission to access your audio hardware. If those don't work, the issue is usually a setting buried in Discord's audio menu or a problem with how your computer recognizes your headset or microphone.

The fastest way to narrow down the cause is to test whether the problem is Discord-specific or affects all your apps. Try opening a video call in Google Meet or Zoom. If those work but Discord doesn't, the problem is Discord's settings or permissions. If nothing with audio works, the problem is your computer's audio setup or internet connection.

Key Takeaways

  • Restart Discord completely (close it fully, then reopen it) before trying anything else — this fixes roughly half of connection problems.
  • Check that Discord has microphone and speaker permission in your operating system settings, which Windows and macOS sometimes revoke after updates.
  • Make sure your microphone and headset are set as the default audio devices in your computer's sound settings, not just plugged in.
  • Test your internet connection by opening a web browser and loading a website; if the internet is down, Discord calls won't connect even if the app appears to be working.
  • If Discord connects but you can't hear anyone, the problem is usually your speaker or headset settings, not your microphone or internet.

Restart Discord and check your internet first

Close Discord completely — don't just minimize it. On Windows, right-click the Discord icon in the system tray (bottom right corner) and select "Quit Discord". On macOS, click Discord in the menu bar and select "Quit Discord". Wait 10 seconds, then reopen the app. This clears Discord's memory and forces it to reconnect to the servers fresh.

While Discord is closed, open your web browser and load a website like Google.com. If the page loads, your internet is working. If it doesn't load or loads very slowly, your internet connection is down or unstable — Discord can't connect to calls without it. Restart your router by unplugging it for 30 seconds, plugging it back in, and waiting for the lights to stabilize before opening Discord again.

Give Discord permission to use your microphone and speakers

Discord needs explicit permission from your operating system to access your microphone and speakers. Windows and macOS sometimes remove these permissions after system updates, which is why Discord calls stop working even though nothing changed on your end.

On Windows 10 or 11: Open Settings, go to Privacy & Security, then Microphone. Scroll down and make sure the toggle next to Discord is turned on (it should be blue). Do the same for Camera if you plan to use video calls. Then go back to Privacy & Security, select Camera, and turn on Discord there too if you use video.

On macOS: Open System Settings, go to Privacy & Security, then Microphone. Look for Discord in the list and make sure it's checked. Do the same for Camera. If Discord isn't in the list, it means you've never given it permission — close Discord, go back to these settings, and the next time you open Discord it will ask for permission. Click "Allow".

Set your microphone and headset as default audio devices

Discord uses whatever microphone and speakers your computer has set as default. If you plugged in a headset but didn't set it as default, Discord will try to use your built-in laptop microphone and speakers instead, which often don't work well for calls.

On Windows: Right-click the speaker icon in the system tray (bottom right), select "Open Volume mixer", then scroll down to "Advanced" and click "Volume and device preferences". Under "Input" you'll see your microphone — click the dropdown and select your headset microphone. Under "Output" you'll see your speakers — click the dropdown and select your headset speakers or headphones.

On macOS: Click the Apple menu, go to System Settings, then Sound. Under "Input" select your microphone from the list. Under "Output" select your headphones or speakers. If your headset doesn't appear in either list, unplug it, wait 5 seconds, and plug it back in — macOS sometimes needs a moment to recognize new devices.

Check Discord's audio settings

Open Discord, click the gear icon next to your username (bottom left), and go to Voice & Video. Under "Input Device" make sure your microphone is selected — if it says "Default" or shows a device you don't recognize, click the dropdown and select your actual microphone. Do the same for "Output Device" and your speakers or headphones.

Scroll down to "Input Sensitivity" and make sure it's not set all the way to the left (which mutes your microphone). A good starting point is somewhere in the middle. If you're not sure, click "Let Discord automatically adjust my input sensitivity" — this usually works better than manual adjustment.

If you see a red X next to your microphone or speaker in these settings, Discord can't detect that device. Unplug your headset or microphone, wait 10 seconds, and plug it back in. If the X doesn't go away, try a different USB port or restart your computer.

Test your microphone and speakers in Discord

In the Voice & Video settings, scroll down to "Mic Test" and click the button that says "Let's Check". Discord will record a short message from your microphone and play it back to you. If you hear your own voice, your microphone is working. If you don't hear anything, your microphone isn't working or Discord can't access it.

If the mic test works but you still can't connect to calls, the problem is usually your internet connection or Discord's servers. Try joining a call in a different Discord server to see if the problem is specific to one server. If you can't connect to any calls, restart your router and try again.

Disable hardware acceleration if Discord keeps crashing during calls

Some computers have trouble with Discord's hardware acceleration feature, which uses your graphics card to speed up the app. If Discord crashes or freezes when you try to join a call, this might be the cause. Open Discord settings, go to Advanced, and turn off "Hardware Acceleration". Restart Discord and try joining a call again.

This will make Discord slightly slower on your computer, but it's worth it if it stops the crashes. If Discord still crashes after you turn off hardware acceleration, the problem is likely a conflict with another app or a driver issue, and you may need to reinstall Discord or update your graphics drivers.

Frequently Asked Questions

Why can I hear people in Discord calls but they can't hear me?

Your microphone isn't working or Discord doesn't have permission to use it. Go to Voice & Video settings and run the mic test — if you don't hear your own voice, your microphone isn't set up right. Check that Discord has microphone permission in your operating system settings and that your microphone is set as the default input device.

Discord says I'm connected to a call but I can't hear anyone

Your speakers or headphones aren't working or Discord doesn't have permission to use them. In Voice & Video settings, make sure your speakers or headphones are selected under "Output Device". Check that Discord has speaker permission in your operating system settings. If you're using a headset, unplug it and plug it back in — sometimes Windows or macOS stops recognizing it.

Why does Discord say "No Route" when I try to connect?

This usually means Discord can't reach its servers, which is a network problem on your end. Restart your router and try again. If that doesn't work, check whether other apps can connect to the internet — open a web browser and load a website. If nothing connects, your internet is down. If other apps work but Discord doesn't, Discord's servers might be having problems; check the Discord status page at status.discord.com.

I updated Windows and now Discord calls won't work

Windows updates often reset app permissions. Go to Settings, Privacy & Security, Microphone, and turn Discord back on. Do the same for Camera. Then restart Discord and try joining a call again. This fixes the problem for most people after a Windows update.

Can I use Discord calls on WiFi or do I need ethernet?

WiFi works fine for Discord calls as long as your connection is stable. If you keep dropping from calls or the connection is choppy, try moving closer to your router or switching to ethernet if you can. If your WiFi is shared with many other devices, they might be using up the bandwidth — ask others to stop streaming or downloading while you're on a call.
