+## Case Name: check-8bit-play-rec
+## Preconditions:
+##    - sox installed
+## Description:
+##    This test verifies 8-bit audio playback and recording functionality using ALSA devices.
+##    It generates test chirp signals in multiple 8-bit formats (unsigned 8-bit, A-LAW, MU-LAW), plays them back, records the output,
+##    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.
+## Case steps:
+##    1. Generate chirp signals in unsigned 8-bit, A-LAW, MU-LAW, and S32_LE formats using sox.
+##    2. Play each chirp file and record the output using arecord and aplay with the specified ALSA devices.
+##    3. Convert raw recordings to WAV format for analysis.
+##    4. Analyze the recorded files for integrity.
+## Expected results:
+##    - All chirp files are played and recorded without errors.
+##    - The recorded files are successfully generated and converted.
+##    - No failures are reported during analysis.

+##    3. Save both recorded files into the log directory for later analysis.
+##    4. Analyze the recorded files for integrity and correct format.
