## Case Name: check-performance
## Preconditions:
##    N/A
## Description:
##    Run aplay and arecord to playback and capture
##    pipelines of the benchmark topology:
##        sof-hda-benchmark-generic-PLATFORM.tplg
## Case step:
##    1. Parse TPLG file to get pipeline with type of playback
##       and capture (exclude HDMI pipeline)
##    2. Specify the audio parameters
##    3. Run aplay and arecord on each pipeline with audio parameters
## Expect result:
##    The return value of aplay/arecord is 0
##    Performance statistics are printed
##
