## Case Name: check-8bit-play-rec
5+
## Preconditions:
6+
## - sox installed
7+
## Description:
8+
## This test verifies 8-bit audio playback and recording functionality using ALSA devices.
9+
## It generates test chirp signals in multiple 8-bit formats (unsigned 8-bit, A-LAW, MU-LAW), plays them back, records the output,
10+
## and checks the integrity of the recorded files. The test ensures that the pipeline correctly handles 8-bit audio data for both playback and capture.
11+
## Case steps:
12+
## 1. Generate chirp signals in unsigned 8-bit, A-LAW, MU-LAW, and S32_LE formats using sox.
13+
## 2. Play each chirp file and record the output using arecord and aplay with the specified ALSA devices.
14+
## 3. Convert raw recordings to WAV format for analysis.
15+
## 4. Analyze the recorded files for integrity.
16+
## Expected results:
17+
## - All chirp files are played and recorded without errors.
18+
## - The recorded files are successfully generated and converted.
19+
## - No failures are reported during analysis.

## Case Name: check-float-play-rec
5+
## Preconditions:
6+
## - sox installed
7+
## Description:
8+
## Verify float audio playback and capture using ALSA devices. The test generates a float-encoded chirp and a 32-bit signed integer chirp,
9+
## plays one while recording the other format and vice versa. This validates that the audio pipeline correctly handles FLOAT and S32_LE sample formats
10+
## and that sample conversion between formats works as expected.
11+
## Case steps:
12+
## 1. Generate a 48 kHz stereo chirp in 32-bit float and 32-bit signed integer formats using sox.
13+
## 2. Use arecord/aplay to play the float chirp and record with S32_LE format, then play the S32_LE chirp and record with FLOAT_LE format.
14+
## 3. Save both recorded files into the log directory for later analysis.
15+
## 4. Analyze the recorded files for integrity and correct format.
16+
## Expected results:
17+
## - Both playback and recording complete without errors.
18+
## - The recorded files are created in the log directory and match expected sample formats.
19+
## - No failures are reported during analysis.
