QA:Testcase alsa

Description

The alsa-lib (Advanced Linux Sound Architecture library) is a library that provides audio and MIDI functionality to the Linux operating system. It's a fundamental part of the Linux audio infrastructure. This test case ensures that the alsa-lib can correctly provide details about the audio hardware and its capabilities.

Setup

Ensure that alsa-lib and alsa-utils are installed on your Fedora system. A sound card or onboard audio chipset should be present.

How to test

1. Open a terminal.
2. Use the aplay utility (from alsa-utils) to list sound cards and digital audio devices: aplay -l.
3. For more detailed information about cards' capabilities, use: aplay -L.
4. Optionally, you can use amixer to get the current volume levels or mute/unmute the sound card: amixer sget Master.

Expected Results

1. The aplay -l command should list all the sound cards and digital audio devices available on the system.
2. The aplay -L command should provide detailed descriptions and capabilities of the sound cards.
3. The amixer sget Master command should provide details about the Master volume level and state (e.g., unmuted/muted).
4. No errors should be encountered during the process.

Optional

For a more extensive test: 1. Play a sample WAV file using aplay /path/to/sample.wav and ensure it plays correctly. 2. Use amixer to change volume levels or mute/unmute and verify changes are applied to the sound output.
