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
- Ensure your configuration is correct according to the first few steps of the basic test case
- Shut your system down entirely, then start it up again and log in to the desktop
- Run the GNOME volume control application:
gnome-volume-control - Go to the Input tab
- 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)
- Check the Input volume: slider is set above zero, and the corresponding Mute box is not checked
- Produce some sound (speak into the microphone, or play sound into the line input, etc), and observe the Input level: meter
- Experiment with changing the Input volume: slider as you play sound
- Optionally, actually attempt to record some sound: you can use the
audacity
Expected Results
- 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
- Recording sound should work correctly
