#!/usr/bin/env bash

##
## Case Name: verify PCM list with tplg file
## Preconditions:
##    driver already inserted with modprobe
## Description:
##    using /proc/asound/pcm to compare with tplg content
## Case step:
##    1. load tplg file to get pipeline list string
##    2. load /proc/asound/pcm to get pcm list string
##    3. compare string list
## Expect result:
##    pipeline list is same as pcm list
