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