##
## Case Name: check-userspace-parecord
## Preconditions:
##    N/A
## Description:
##    Go through all the sources and parecord on the sources whose
##    active port is available (jack connected) or unknown (DMIC)
## Case step:
##    1. go through all the sources
##    2. check the source's active port is available or not
##    3. parecord on the active port which is available or unknown
## Expect result:
##    parecord on the source successfully
##
