Description

This test case tests whether audio input (recording) works correctly. You will need a working input hardware configuration - for instance, a microphone connected to a microphone input on a sound card, a USB microphone, a typical sound-producing device with a line-level output connected to the line-in on a sound card...


How to test

  1. Ensure your configuration is correct according to the first few steps of the basic test case
  2. Shut your system down entirely, then start it up again and log in to the desktop
  3. Run the GNOME volume control application: gnome-volume-control
  4. Go to the Input tab
  5. Ensure the correct device is selected in the box at the bottom, and the correct connector is selected in the Connector: drop-down box (if applicable; for a device with only a single possible input channel, such as a USB microphone, it will not be present)
  6. Check the Input volume: slider is set above zero, and the corresponding Mute box is not checked
  7. Produce some sound (speak into the microphone, or play sound into the line input, etc), and observe the Input level: meter
  8. Experiment with changing the Input volume: slider as you play sound
  9. Optionally, actually attempt to record some sound: you can use the audacity package for this purpose

Expected Results

  1. The Input level: meter should indicate input is being received when you produce sound with everything correctly configured. The higher the Input volume: slider, the higher the level indicated by the Input level: meter should be for the same level of sound produced
  2. Recording sound should work correctly
