##
## Case Name: volume-basic-test
## Preconditions:
##    aplay should work
##    At least one PGA control should be available
## Description:
##    Set volume from 0% to 100% to each PGA
## Case step:
##    1. Start aplay
##    2. Set amixer command to set volume on each PGA
## Expect result:
##    command line check with $? without error
