I encountered an issue with a Raspberry Pi 5 where an external USB microphone was properly detected (arecord -l showed it under card 3), but no audio was being captured — recordings were silent, and arecord -V mono showed no input level activity.
Swapping the USB mic for a different model immediately resolved the problem. Audio capture now works correctly, and speech recognition integration with ChatGPT via the Sunfounder PiCar-X stack is functional. Can you help me
Here are some troubleshooting steps to help resolve the issue:
1.Try a Different USB Port
Please test the microphone on another USB port to rule out any port-specific issues.
2.Verify Software Installation
Ensure all required software packages and dependencies are installed correctly.
3.If you encounter any errors during installation, kindly share a screenshot of the error message so we can assist further.
4.Test Microphone Functionality
Run the following commands to check if the microphone is working:
rec -c 1 op.wav
sudo play op.wav
This will record a short audio clip and play it back.
If the issue persists after these steps, we’ll arrange a replacement USB microphone for you at no additional cost.
Please let us know the results of these tests, and we’ll proceed accordingly. We appreciate your patience and cooperation!
