To set up Discord audio correctly for gaming, open User Settings, go to Voice & Video, and manually select your headset as both the input and output device – never leave it on “Default.” From there, enable noise suppression, set input sensitivity, and adjust attenuation so teammates come through clearly without drowning out game sound. Most Discord audio problems come from three places: wrong device selected, sensitivity set too low, or conflicting noise processing. This guide walks through every setting that matters and skips the ones that do not. See the full PC gaming troubleshooting guide for deeper context.
Bad Discord audio ruins gaming sessions faster than bad aim. Your squad cannot coordinate a push in Valorant if half the team sounds like they are talking through a tin can, and nobody wants to hear your mechanical keyboard every time your mic opens. Getting this right takes about five minutes.

Discord Audio Settings at a Glance
Discord buries its audio controls across multiple submenus. Here is where everything lives and what each setting actually does.
Step 1: Select the Correct Input and Output Devices
Open Discord and click the gear icon next to your username to enter User Settings. Navigate to Voice & Video. The first two dropdowns are Input Device and Output Device.
Do not leave either one on “Default.” Windows changes its default audio device whenever you plug in headphones, connect a Bluetooth device, or update a driver. If Discord is set to Default, your audio routing can silently break mid-session. Instead, manually select your specific headset or microphone from the dropdown.
How to Identify Your Devices
If you see a list of confusing device names, open Windows Sound Settings (right-click the speaker icon in the taskbar) and match the names. Your gaming headset usually shows up as its brand name – “HyperX Cloud II” or “SteelSeries Arctis Nova 7” – rather than a generic “Microphone” label. USB headsets appear as their own device. Headsets plugged into a 3.5mm jack show up under your motherboard’s audio chipset, often labeled “Realtek” or similar.

Hit the “Let’s Check” button under the mic test section. Speak at your normal gaming volume and watch the bar. It should bounce into the green zone without hitting red. If nothing moves, you picked the wrong input device.
Step 2: Set Your Input Volume and Sensitivity
The Input Volume slider controls how loud Discord receives your mic signal. Start at 80-100%. If teammates say you are too loud, drop it to 60-70%. If they say you are quiet, make sure you are at 100% before touching anything else.
Input Sensitivity (Voice Activity Mode)
If you use Voice Activity instead of Push to Talk, the sensitivity slider determines what volume triggers your mic to open. Discord draws a yellow bar showing the current threshold and a green bar showing your live mic input.
Set the threshold just below your normal speaking voice. Too low and your mic stays open – transmitting keyboard clicks and breathing. Too high and your first syllable gets clipped every time you start talking. Most gamers land between -40dB and -50dB depending on their mic and room noise.
Why Push to Talk Is Better for Most Gamers
Voice Activity has a fundamental problem: it cannot distinguish between sounds it should transmit and sounds it should not. Your voice, your keyboard, a cough, your dog barking – if it crosses the volume threshold, it goes to your teammates.
Push to Talk solves this completely. Audio only transmits while you hold a key. Set the keybind to a mouse side button (Mouse 4 or Mouse 5) or a key your gaming hand does not touch, like Caps Lock or a numpad key. The brief delay of pressing a button is a small tradeoff for guaranteed clean audio.
The exception: if you play games that demand constant communication (raid leading in MMOs, in-game leading in competitive shooters) and you have a quiet room with a good mic, Voice Activity makes sense. For everyone else, Push to Talk.
Step 3: Configure Noise Suppression
Scroll down in Voice & Video settings to find the noise suppression toggle. Discord uses Krisp AI to filter background noise in real time. Flip it on.
Krisp handles everyday gaming sounds well – mechanical keyboards, case fan hum, mouse clicks, moderate AC noise. It runs on your CPU and adds about 30ms of latency to your mic signal, which is invisible in voice chat.
When to Leave It Off
Krisp struggles with two things. First, sustained loud noise like someone vacuuming in the next room or a window AC unit at full blast. The algorithm tries to separate speech from noise and fails, creating robotic artifacts. Second, if you already run NVIDIA Broadcast or AMD Noise Suppression on your system, adding Krisp on top double-processes your voice and makes it sound worse.
The rule: use one noise suppression tool, not two. If you run Broadcast or AMD’s tool at the system level, disable Discord’s built-in Krisp. If you do not run any external noise processing, turn Krisp on.
Which Noise Suppression Should You Use?
Step 4: Dial In Output Volume and Attenuation
Output Volume controls how loud you hear other people in Discord. Set this to 70-80% as a starting point. If specific people are too loud or too quiet, right-click their name in the voice channel and adjust their individual volume slider. Per-user volume ranges from 0% to 200% and overrides the global setting.
Attenuation Settings
Attenuation is the most overlooked Discord setting for gamers. It automatically ducks your game audio when someone talks in voice chat. Without it, loud game audio drowns out callouts. With it turned too high, your game goes nearly silent every time someone opens their mic.
Go to Voice & Video and scroll to Attenuation. Set the slider to 50-70%. Enable “When others speak” and disable “When I speak.” You want the game to quiet down when teammates make callouts, but you do not want your own game audio cutting out every time you press Push to Talk.
This setting makes a huge difference in competitive games. In Valorant, hearing a teammate’s callout about an enemy position matters more than hearing ambient footsteps for that split second. In single-player games, turn attenuation off – there is no reason to duck audio when nobody is making tactical calls.
Step 5: Disable Automatic Gain Control
Automatic Gain Control (AGC) is enabled by default in Discord. It adjusts your mic volume on the fly, boosting quiet speech and reducing loud speech. In theory, this keeps your volume consistent. In practice, it creates a pumping effect where the volume jumps around unpredictably.
AGC boosts your mic gain during silence, amplifying background noise between sentences. Then when you start talking, it slams the gain back down, creating an audible “pump” that your teammates hear as sudden volume shifts. This is especially bad with mechanical keyboards – the gain boost picks up keystrokes at full volume during pauses.
Disable AGC and set your input volume manually instead. Speak at your normal volume, watch the input bar, and adjust until your voice sits comfortably in the green zone. This is a set-it-once adjustment that produces more consistent results than any automatic system.
Step 6: Increase Voice Channel Bitrate
Voice channel bitrate controls the audio quality of everyone in the channel. Discord defaults to 64kbps, which sounds muddy and compressed – like a phone call from 2005. If you have server management permissions, bump this up.
Edit the voice channel, find the bitrate slider, and set it to 96kbps. This produces noticeably clearer voice audio without putting meaningful strain on anyone’s internet connection. 96kbps uses about 12KB per second of bandwidth per person, which is nothing on modern connections.
Servers with Nitro boosts unlock higher bitrates up to 128kbps (Level 1), 256kbps (Level 2), and 384kbps (Level 3). For gaming voice chat, 96kbps is the sweet spot. The jump from 64 to 96 is obvious. The jump from 96 to 128 is subtle. Beyond 128kbps you are spending Nitro money for differences most people cannot hear over game audio.
Step 7: Audio Subsystem and QoS
At the bottom of Voice & Video settings, you will find the Audio Subsystem dropdown and the QoS toggle. These are the settings most guides skip, but they matter for specific situations.
Audio Subsystem
Leave this on “Standard” unless you have audio issues. The “Legacy” option uses an older Windows audio pipeline that fixes compatibility problems with some USB headsets and audio interfaces. If your mic randomly cuts out, produces static, or fails to appear in the device list, switch to Legacy and restart Discord. That fixes about 80% of weird device detection issues.
Quality of Service (QoS)
The QoS High Packet Priority toggle tells your network adapter to prioritize Discord voice packets over other traffic. On a busy home network where someone is streaming Netflix while another person downloads a game, QoS helps keep your voice chat smooth. On a network where you are the only user, it makes no measurable difference.
One caveat: some older routers interpret QoS packets incorrectly and actually throttle them. If your voice chat gets worse after enabling QoS, turn it back off. This is a router firmware problem, not a Discord problem.
Common Mistakes That Ruin Discord Audio
- Leaving Input Device on “Default.” Windows reassigns the default device after updates, driver installs, or plugging in new hardware. One day your headset mic works fine, the next day Discord is using your webcam mic or monitor speakers without telling you. Always manually select the device.
- Running Discord noise suppression on top of NVIDIA Broadcast. Both tools apply AI-based noise removal to your mic. The second layer processes already-processed audio, creating choppy, robotic sound. Pick one. If you use Broadcast system-wide, turn Krisp off in Discord.
- Setting input sensitivity too low with Voice Activity. The mic stays open constantly, broadcasting every keystroke, breath, and background sound. Either raise the threshold until it only opens on speech, or switch to Push to Talk.
- Leaving Automatic Gain Control enabled. AGC boosts gain during silences, amplifying background noise. Then it slams gain down when you speak, causing audible volume pumping. Set your input volume manually and disable AGC.
- Never checking voice channel bitrate. The default 64kbps sounds noticeably worse than 96kbps. If you manage the server, this is a two-second fix that improves clarity for everyone. Most server owners never touch this setting.
- Using speakers instead of headphones for voice chat. Your speakers broadcast game audio into the room, your mic picks it up, and teammates hear an echo of themselves. Closed-back headphones eliminate this feedback loop entirely.
How Discord Processes Your Audio
Understanding the signal path helps you troubleshoot when something sounds off. Here is what happens to your voice from the moment you speak to the moment your teammates hear you.
Each stage in this chain can introduce problems. If nobody hears you, the issue is usually in stages 1-4 (wrong device, low volume, or server mute). If you sound robotic or choppy, look at stages 4-5 (double noise processing, low bitrate, or high network latency). If teammates sound bad to you, the problem is at stage 6-7 (their settings or your output config).
Quick Fixes for Common Discord Audio Problems
Nobody Can Hear Me
Check the input device in Voice & Video. If it says “Default,” change it to your specific mic. Open the mic test and confirm the bar moves when you speak. If it does not move at all, your mic is not connected, not powered, or Windows itself does not recognize it. Open Windows Sound Settings and check if the mic appears there first.
Also check if you are server muted or self-muted. The mic icon at the bottom of Discord shows a red slash when muted. Right-click your name in the voice channel and verify “Server Mute” is not checked.
I Sound Too Quiet
Raise Discord input volume to 100%. If that is not enough, open Windows Sound Settings, find your microphone, go to Properties, and increase the input level. Avoid using the Microphone Boost slider beyond +10dB – if your mic needs boost that high, the mic itself is the problem (too far away or too low sensitivity).
I Hear Echo of Myself
Someone in the voice channel is playing your audio through speakers, and their mic picks it up and sends it back to you. The fix is on their end – they need headphones. If the echo is coming from your own setup, enable Echo Cancellation in Discord settings and make sure you are using headphones, not speakers.
Teammates Sound Distorted
Check your voice channel’s region in channel settings. If the server region is far from most members, voice routes through distant servers with higher latency. Change it to the closest geographic region. Also check if the channel bitrate is set below 64kbps – some older servers still run at 32kbps, which makes everyone sound like a walkie-talkie.
Audio Cuts Out Randomly
This is usually a network problem, not a Discord settings problem. Run a ping test to Discord’s servers (open Command Prompt and type ping discord.gg). If you see packet loss or ping spikes above 200ms, the issue is your internet connection. Switch from Wi-Fi to Ethernet if possible. If you must use Wi-Fi, move closer to your router or switch to the 5GHz band.
If your connection is stable but audio still drops, switch the Audio Subsystem from “Standard” to “Legacy” in Discord settings. This fixes driver compatibility issues with certain USB headsets and audio interfaces.
Discord Audio Setup – Quick Reference by Situation
Different gaming setups need different Discord audio configurations. Here is a fast lookup based on your situation.
If you play competitive FPS (Valorant, CS2, Apex) with a squad: Push to Talk, Krisp on (unless using Broadcast), attenuation at 60-70%. You need to hear callouts over game audio, and your teammates should never hear your keyboard during clutch rounds.
If you raid or play MMOs with large groups: Push to Talk is mandatory in large voice channels. AGC off, Krisp on. Set attenuation to 50% so boss music does not overpower the raid leader. Ask your server admin to bump bitrate to 96kbps.
If you play casual co-op games with friends: Voice Activity with sensitivity set just below your speaking volume works fine. Krisp on, attenuation at 40-50% or off. Casual sessions are more about conversation than tactical callouts.
If you stream on Twitch while in Discord: Route audio through NVIDIA Broadcast (or OBS filters if no RTX GPU). Krisp off in Discord. Set a separate audio output for Discord in your streaming software so you can control voice chat volume independently of game audio in your stream mix.
If your mic sounds bad no matter what you try: The headset mic is probably the bottleneck. Budget headset mics pick up everything and compress your voice into a narrow frequency range. A dedicated USB microphone like the HyperX SoloCast paired with a boom arm produces dramatically better results for voice chat. Check Price on Amazon

Frequently Asked Questions
Why can nobody hear me in Discord?
The most common cause is the wrong input device selected. Go to User Settings, then Voice & Video, and check the Input Device dropdown. Make sure it shows your actual headset or microphone – not “Default.” The Default option sometimes picks the wrong device after Windows updates or when multiple audio devices are connected.
Also check that your input volume slider is above 50% and that you are not server-muted. The mic icon at the bottom of Discord shows a red slash when muted.
Should I use Push to Talk or Voice Activity in Discord?
Push to Talk is better for gaming. It blocks all background noise when you are not pressing the key – your teammates never hear your keyboard, fan noise, or someone talking in the next room. Set the keybind to a mouse side button or a key your gaming hand does not use, like Caps Lock.
Voice Activity works if you have a quiet room and a good noise-cancelling microphone, but it will broadcast unwanted sounds in most gaming setups.
What is Discord attenuation and should I turn it on?
Attenuation automatically lowers the volume of other applications when someone speaks in Discord. Set it to 50-70% so you can still hear game audio while understanding callouts. Enable “When others speak” and disable “When I speak.”
Attenuation is useful in team games where voice communication matters. Turn it off for single-player games or when listening to music.
Why does my mic sound robotic or choppy in Discord?
Robotic or choppy mic audio usually points to network problems or conflicting audio processing. Check your ping in the voice channel – anything above 100ms causes voice distortion. If your connection is stable, the problem is likely stacked noise suppression. Disable Krisp in Discord if you already run NVIDIA Broadcast or another noise filter.
Low channel bitrate (under 64kbps) also causes compression artifacts that make voices sound mechanical.
How do I stop hearing my own voice echo in Discord?
Echo means your mic is picking up audio from speakers or headphone bleed. The fastest fix is wearing closed-back headphones instead of using speakers – this eliminates the feedback loop entirely. If you already use headphones and still hear echo, enable Echo Cancellation in Discord Voice & Video settings.
Also turn down your headphone volume. At high levels, sound leaks out of the ear cups and re-enters your microphone.
