How to Fix Crackling or Choppy Audio in Discord on PC
Source-checked About 10 minutes
Answer
Confirm the correct Discord input and output devices, test them outside Discord, reset Voice & Video settings, compare the audio subsystem, and disable Quality of Service only as a measured test.
Test the device outside Discord
Play and record audio in another trusted app. Reconnect a wired or USB headset and try another port so a device fault is not mistaken for a Discord setting.
Select the exact devices
Open User Settings > Voice & Video and choose the intended Input Device and Output Device instead of Default. Set safe volumes and run Discord's mic test.
Check Windows sound routing
Open Settings > System > Sound > Volume mixer and confirm Discord uses the same intended output and input without an extreme per-app volume.
Reset Discord voice settings
In Voice & Video, open the Debugging section and select Reset Voice and Video Settings, then reselect the devices and test again.
Match the system sample format
In Windows Sound settings, open the intended device's advanced properties and note its current format. If another app changed it, test a common supported format and avoid extreme sample rates that the headset or interface does not support.
Compare Discord's audio controls
Test Standard versus Legacy audio subsystem when offered, and turn off Quality of Service High Packet Priority for one call to compare the same connection.
Update and document
Update Discord, Windows, and the device manufacturer's audio driver, restart, then record the device name, connection type, and whether local recordings also crackle.
Video walkthrough
If it does not work
- If only one server or call is affected, compare another voice channel before reinstalling Discord.
- If all system audio crackles, stop changing Discord settings and diagnose the audio device, driver, cable, or system load.
