## Case Name: verify-bootsequence.sh
## Preconditions:
##    UCMv2 is installed in /usr/share/alsa/ucm2 folder
## Description:
##    Run alsactl init to test the initialization settings are correct or not
## Case step:
##    1. check the alsa-lib, alsa-utils version
##    2. save the original amixer settings
