##
## Case Name: check-signal-stop-start
## Preconditions:
##    N/A
## Description:
##    Run aplay/arecord on each pipeline and use SIGSTOP and SIGCONT to
##    simulate keyboard inputs ctrl+z and fg.
##    kill -SIGSTOP $pid will stop the thread
##    kill -SIGCONT $pid will start the thread
## Case step:
##    1. aplay/arecord on PCM
##    2. send SIGSTOP/SIGCONT to stop/start
## Expect result:
##    no errors for aplay/arecord
##
