How to Fix Discord Audio Issues: No Sound, Static, Echo (2026)

The fastest way to fix Discord audio issues is to check your input/output device selection in Discord’s Voice & Video settings – the wrong device is selected about 60% of the time. If you hear nothing, get static, or your friends complain about echo, the fix usually takes under two minutes once you know where to look. For more context, see our PC gaming troubleshooting guide.

This guide covers every common Discord audio problem: no sound at all, crackling or static noise, echo and feedback loops, mic not picking up your voice, and audio cutting out mid-conversation. Start with the quick checks below – most people solve their issue before reaching the advanced fixes.

Fix: No Sound at All in Discord

You joined a voice channel, you see the green ring showing someone is talking, but you hear nothing. This is the most common Discord audio complaint and almost always comes down to output device selection.

1. Select the Correct Output Device

Open Discord and go to User Settings (gear icon) > Voice & Video. Under “Output Device,” check what is selected. If it says “Default,” Discord is using whatever Windows has set as the system default – which might not be your headset.

Click the dropdown and pick your headset or speakers by name. If you use a USB headset, it shows up as a separate audio device. If you use a 3.5mm headset plugged into your motherboard, it is usually called “Speakers (Realtek)” or similar.

2. Check All Volume Levels

Discord has its own output volume slider separate from Windows. Make sure both are turned up:

• Discord: User Settings > Voice & Video > Output Volume slider (drag it to at least 80%)
• Windows: Right-click the speaker icon in your taskbar > Open Volume Mixer. Make sure the Discord slider is not muted or turned down
• Per-user volume: Right-click a person’s name in the voice channel. Each user has an individual volume slider – if someone set it to zero, you will not hear that person even with everything else at max

3. Check If You Are Server Deafened

Look at the bottom-left corner of Discord where your username shows. If you see a headphone icon with a line through it, you deafened yourself. Click the headphone icon to un-deafen. Server admins can also server-deafen members – if the icon persists and you cannot toggle it, ask an admin to check your permissions.

Fix: Static and Crackling in Discord

Crackling, buzzing, or static during voice chat usually points to a hardware conflict or audio processing issue. The sound might come and go, or it might be constant. Here are the fixes in order of likelihood.

1. Toggle Discord’s Audio Processing

Discord applies noise suppression, echo cancellation, and automatic gain control by default. Sometimes these filters conflict with your headset’s built-in processing and create artifacts.

Go to User Settings > Voice & Video and scroll to “Audio Processing.” Try toggling these one at a time:

• Noise Suppression – Switch between Krisp, Standard, and None. Krisp is aggressive and can distort audio on some setups
• Echo Cancellation – Turn it off if your headset already handles echo cancellation in hardware
• Automatic Gain Control – This boosts quiet sounds and cuts loud ones. Disable it if you hear pumping or breathing artifacts

2. Match Your Audio Sample Rate

A sample rate mismatch between Windows and your headset driver causes crackling that sounds like tiny pops every few seconds. Here is how to fix it:

1. Right-click the speaker icon in your taskbar and select Sound settings
2. Click your output device, then click Additional device properties
3. Go to the Advanced tab
4. Set the default format to 24-bit, 48000 Hz (this matches Discord’s internal sample rate)
5. Do the same for your input device (microphone)

If your headset software forces a different sample rate (like 44100 Hz), set Windows to match the headset instead. The goal is consistency – both sides need the same rate.

3. Fix USB Interference

USB headsets and USB microphones can pick up electrical noise from other USB devices. If your headset shares a USB controller with a high-draw device (RGB hub, external drive, USB fan), the electrical noise bleeds into the audio signal.

Move your headset to a different USB port – ideally a rear motherboard port that is not next to other USB devices. USB 2.0 ports sometimes have less noise than USB 3.0 ports for audio devices because the 3.0 data lines generate more electromagnetic interference.

Fix: Echo and Feedback in Discord

Echo in Discord means someone’s output audio is feeding back into their microphone. The person causing the echo usually cannot hear it themselves – their teammates hear it. If everyone tells you that you are echoing, the problem is on your end.

1. Use Headphones Instead of Speakers

This is the number one cause of echo in Discord. If you play audio through speakers while your microphone is active, the mic picks up the speaker output and sends it back to everyone else. There is no software fix that works as well as just putting on headphones.

Even low-volume speakers cause echo if your mic is sensitive. If you must use speakers, switch to Push to Talk so your mic is only active when you press the key.

2. Disable Stereo Mix and Audio Monitoring

Windows has a feature called Stereo Mix that loops your output audio back into an input channel. If Discord grabs Stereo Mix as your input device, it sends everything you hear right back to the voice channel.

1. Right-click the speaker icon > Sound settings > scroll to More sound settings
2. Go to the Recording tab
3. Right-click Stereo Mix and select Disable
4. Also disable any “What U Hear” or “Loopback” devices

If you use a USB audio interface or mixer, check for a “Direct Monitor” or “Monitor” button. Direct monitoring plays your mic back through your headphones locally, but some interfaces route it back into the system audio too.

3. Configure Echo Cancellation

If headphones are not an option, make sure Discord’s echo cancellation is turned on. Go to User Settings > Voice & Video > Audio Processing and enable Echo Cancellation. This works decently for casual calls but struggles during loud gaming sessions where explosions and gunshots blast through your speakers.

Fix: Mic Not Working in Discord

You can hear everyone else, but nobody hears you. Your mic works in other apps. What gives?

1. Verify Input Device Selection

Same as the output device fix – go to User Settings > Voice & Video and check the Input Device dropdown. Select your microphone by name instead of leaving it on “Default.” If you see multiple entries for the same mic (common with USB headsets), try each one until you find the working input.

Test it right there: speak into your mic and watch the green bar under “Input Sensitivity.” If it does not move at all, Discord is not receiving audio from that device.

2. Adjust Input Sensitivity

Discord has a voice activation threshold that ignores sounds below a certain volume. If this threshold is set too high, it filters out your voice entirely.

1. In Voice & Video settings, scroll to Input Sensitivity
2. Toggle off “Automatically determine input sensitivity”
3. Drag the slider to the left so the threshold sits below your speaking volume (watch the green bar as you talk)
4. If your voice barely touches the threshold, you will cut in and out – set the threshold well below your normal speaking level

3. Check Windows Microphone Permissions

Windows 10 and 11 have a privacy setting that blocks apps from accessing your microphone. If Discord does not have permission, it gets zero audio input even when the correct device is selected.

1. Open Settings > Privacy & Security > Microphone
2. Make sure “Microphone access” is toggled On
3. Scroll down and make sure “Let desktop apps access your microphone” is On

This setting resets itself after major Windows updates. If your mic worked last week and suddenly stopped, this is a likely culprit.

Fix: Audio Cutting Out Mid-Call

You hear everyone fine for a minute, then audio drops for a few seconds, comes back, drops again. This pattern points to network problems or Discord server issues rather than audio device problems.

1. Change the Voice Channel Region

Discord picks a voice server region automatically, and sometimes it picks poorly. If you are on the US East Coast routing through a European server, latency causes dropouts.

Channel admins can change the region: click the gear icon next to the voice channel name > Region Override > select the closest geographic region. If you are in a one-on-one call, the caller can change it by clicking the signal indicator.

2. Disable QoS High Packet Priority

Discord has a Quality of Service setting that marks voice packets as high priority on your network. Some routers and ISPs do not handle QoS-tagged packets correctly and actually drop them instead of prioritizing them.

Go to User Settings > Voice & Video and toggle off Enable Quality of Service High Packet Priority. If the cutting-out stops, leave it off. Your router was mishandling the priority tags.

3. Reduce Network Congestion

Discord voice uses about 64 kbps per person – not much bandwidth, but it is sensitive to packet loss and jitter. These network tweaks help:

• Use wired ethernet instead of Wi-Fi. Wi-Fi drops packets during interference, and every dropped packet is a split-second audio gap
• Close bandwidth hogs – pause downloads, turn off cloud backup syncing, and ask your roommates to stop streaming 4K video during your ranked matches
• Restart your router if audio problems started recently. Routers accumulate connection table bloat over time and a reboot clears it

Advanced Fixes

If the standard fixes above did not work, the problem is deeper – usually at the driver or operating system level.

1. Update or Reinstall Audio Drivers

Outdated or corrupted audio drivers cause all kinds of weird behavior: static, dropouts, devices disappearing from the list. Here is the full reset process:

1. Open Device Manager (right-click Start button)
2. Expand Sound, video and game controllers
3. Right-click your audio device and select Uninstall device
4. Check “Delete the driver software” if the option appears
5. Restart your PC – Windows will reinstall a generic driver
6. Then install the latest driver from your motherboard or headset manufacturer’s website

For Realtek audio (most motherboards), download the latest driver from your motherboard manufacturer – not from Realtek’s website directly. Motherboard vendors customize the driver package and the generic Realtek installer sometimes misses features.

2. Reset Discord Voice Settings Completely

Discord stores voice settings locally, and they can get corrupted. The nuclear option:

1. Open User Settings > Voice & Video
2. Scroll all the way to the bottom
3. Click Reset Voice Settings
4. Confirm the reset
5. Close and fully restart Discord
6. Reconfigure your input/output devices from scratch

This clears all custom voice settings including keybinds, noise suppression preferences, and per-user volume adjustments. It is a hassle to reconfigure, but it fixes mysterious issues that no single setting change resolves.

3. Disable Exclusive Mode in Windows

Windows can grant apps exclusive control over an audio device, locking other apps out. If another program grabbed exclusive control before Discord launched, Discord gets no audio.

1. Right-click the speaker icon > Sound settings > click your audio device > Additional device properties
2. Go to the Advanced tab
3. Uncheck “Allow applications to take exclusive control of this device”
4. Do this for both your output device and your input (mic) device
