Why These Issues Happen
System privacy blocks can prevent Discord from seeing the microphone or camera. Permissions must be enabled first.
Only one app can hold the camera or microphone. Background conferencing apps can block Discord.
Wrong device selection or virtual devices cause no audio or distorted sound. Selecting the correct hardware fixes most cases.
Noise suppression or audio filters can distort voice, causing robotic sound.

FAQs
Why does my Discord voice sound robotic?
Noise suppression or network jitter can distort audio. Disable advanced processing, choose the correct mic, and close other apps using bandwidth.
Why is my camera not showing in Discord?
Another app may be using the camera or Discord is blocked. Close other apps, allow camera in system settings, and select the correct device in Discord.
How do I fix “no input detected” in Discord?
Select the correct microphone in Voice & Video, set input sensitivity manually, and ensure system permissions allow microphone access.
Can Discord use virtual devices?
Yes, but virtual devices can fail. If video or audio fails, switch to the physical device in settings.
Should I restart Discord after changes?
Yes. Restart Discord after changing permissions or device selection to clear locks.
How do I test before joining a call?
Use the online mic and webcam tests, then place a test call in Discord to confirm.
