(Redirected from QA:Testcase LxQT ARM audio)
This test case tests whether basic sound playback is successful.
How to test
- Ensure your hardware is correctly connected so you ought to be able to hear sound: i.e., you have speakers or headphones connected to the speaker output on your sound adapter, or a receiver connected to a S/PDIF output.
- Open the sound settings (in GNOME, open Settings -> Sound) and verify that your output sound device is selected (usually called Speakers, Headphones or Line Out) and it has a reasonable volume level (it should not be zero, i.e. muted).
- If your system has multiple sound devices (like a sound card and also a graphics card which can send audio to a monitor), you might need to select the preferred sound output device manually. But at least some output device should always be selected by default.
- For some sound devices and in some desktop environments, you might also need to choose sound profile (like Digital Stereo (IEC958) for S/PDIF) and other attributes.
- Verify that you can hear sounds. If there's a Test button in the sound settings, use it. Otherwise play e.g. some music or perhaps a YouTube video.
- Shut your system down entirely, then start it up again and log in to the desktop
- Run the default desktop media player (in GNOME called Videos).
- Play some music (e.g. the one linked above) or a video in that media player. You should be able to hear the sound playing. You should not have to adjust any default volume settings in order to hear the sound.
- Be aware that only open multimedia codecs are supported by default.
- A failure to play video is not a failure of this test case. This is only about sound playback.
