Troubleshooting Guide

Solutions to common microphone problems

Microphone Not Detected
Problem:

Your browser cannot find any microphone devices, or the microphone test shows "No microphone detected."

Solution:

1. Check physical connections - ensure your microphone is properly plugged in (USB or 3.5mm jack) 2. Try a different USB port if using a USB microphone 3. Check if the microphone is enabled in your operating system settings: - Windows: Settings > Privacy > Microphone > Allow apps to access your microphone - Mac: System Preferences > Security & Privacy > Microphone - Linux: Check PulseAudio or ALSA settings 4. Restart your browser and try again 5. If using an external microphone, try your built-in mic to isolate the issue

Browser Permission Denied
Problem:

The browser blocks microphone access or you accidentally clicked "Block" on the permission prompt.

Solution:

1. Click the camera/microphone icon in your browser's address bar (usually on the left side) 2. Change the permission from "Block" to "Allow" 3. Refresh the page 4. Alternatively, go to browser settings: - Chrome: Settings > Privacy and security > Site Settings > Microphone - Firefox: Preferences > Privacy & Security > Permissions > Microphone > Settings - Safari: Preferences > Websites > Microphone - Edge: Settings > Cookies and site permissions > Microphone 5. Find this website and change permission to "Allow"

Very Low Volume or Quiet Microphone
Problem:

The microphone works but the volume is too low, waveform barely moves, or voice is hard to hear.

Solution:

1. Increase microphone gain in system settings: - Windows: Right-click speaker icon > Sounds > Recording > Select mic > Properties > Levels (set to 80-100) - Mac: System Preferences > Sound > Input > Adjust input volume slider 2. Check if your microphone has a physical gain knob and turn it up 3. Speak closer to the microphone (6-12 inches is ideal for most mics) 4. Remove any foam windscreen or pop filter that might be muffling sound 5. For USB mics, check manufacturer software for gain/volume controls 6. Ensure you're speaking into the correct side of the microphone (check mic orientation)

Audio Clipping or Distortion
Problem:

The waveform hits the top/bottom, quality score is low, or audio sounds distorted/fuzzy.

Solution:

1. Reduce microphone gain/volume in system settings (try 50-70%) 2. Speak further away from the microphone (12-18 inches) 3. Speak at a normal volume - don't yell or speak too loudly 4. Check for physical obstructions or debris in the microphone 5. If using a headset, ensure it's not too close to your mouth 6. Disable any audio enhancements or processing in system settings 7. For USB mics, disable auto-gain control (AGC) if available 8. Try a different USB port or cable - could be interference

Background Noise or Static
Problem:

High noise floor, constant hissing/buzzing sound, or background noise is too loud.

Solution:

1. Move away from noise sources: fans, air conditioning, computers, refrigerators 2. Close windows to reduce outside noise 3. Use noise-canceling features if your mic has them 4. For USB mics, try a different USB port away from power-hungry devices 5. Check for electrical interference - move away from power adapters, monitors, or LED lights 6. Use a shorter cable if possible (long cables can pick up interference) 7. Ground loops: try plugging into a different power outlet 8. For XLR mics, use balanced cables and ensure connections are tight 9. Enable noise suppression in your operating system or recording software

Microphone Cutting In and Out
Problem:

Audio drops randomly, microphone disconnects and reconnects, or intermittent sound.

Solution:

1. Check cable connections - loose cables are the #1 cause 2. Try a different cable if available 3. For USB: try different USB ports, preferably directly on motherboard (not through hub) 4. Update audio drivers: - Windows: Device Manager > Sound controllers > Update driver - Mac: Update macOS to latest version 5. Disable USB power saving: - Windows: Device Manager > USB Root Hub > Power Management > Uncheck "Allow computer to turn off" 6. Check for CPU overload - close unnecessary programs 7. For wireless mics, check battery level and reduce distance to receiver 8. Test with a different microphone to rule out hardware failure

Wrong Microphone Selected
Problem:

Browser is using the wrong microphone (e.g., webcam mic instead of USB mic).

Solution:

1. When prompted for microphone permission, click the dropdown in the permission dialog 2. Select the correct microphone from the list 3. Click "Allow" 4. If already granted permission: - Click camera/mic icon in address bar - Click "Manage" or "Settings" - Change the microphone device - Refresh the page 5. Set default device in system settings: - Windows: Settings > System > Sound > Input > Choose input device - Mac: System Preferences > Sound > Input > Select device 6. In browser settings, you can also manage default devices under site permissions

Echo or Feedback
OS: Windows
Problem:

Hearing your own voice delayed, or high-pitched squealing sound.

Solution:

1. Use headphones to prevent speakers from feeding back into mic 2. Reduce speaker volume 3. Move microphone further from speakers 4. Disable "Listen to this device" in Windows: - Sound Settings > Recording > Mic Properties > Listen > Uncheck "Listen to this device" 5. In conferencing apps, ensure they're not monitoring your mic through speakers 6. Check for duplicate audio sources - close other apps using the microphone 7. Disable audio enhancements that might cause echo

Latency or Delay Issues
Problem:

Noticeable delay between speaking and seeing waveform, high latency reading.

Solution:

1. Close unnecessary browser tabs and applications 2. Use wired connection instead of Bluetooth (Bluetooth adds 100-200ms latency) 3. Update audio drivers to latest version 4. Reduce buffer size in audio settings (if available) 5. For Windows: Use ASIO drivers if doing music production 6. Check CPU usage - high CPU can cause audio latency 7. Disable audio enhancements/effects that add processing time 8. For gaming/streaming, use dedicated audio interface with low-latency drivers

Chrome Specific Issues
Browser: Chrome
Problem:

Microphone problems only in Chrome browser.

Solution:

1. Clear browser cache and cookies 2. Disable Chrome extensions (especially ad blockers) - test in Incognito mode 3. Reset Chrome settings: Settings > Advanced > Reset settings 4. Check Chrome flags: chrome://flags - disable experimental features 5. Update Chrome to latest version 6. Try creating a new Chrome profile 7. Check for conflicting software (some antivirus blocks microphone) 8. Ensure hardware acceleration is enabled: Settings > Advanced > System > Use hardware acceleration
