#The script was written for 2 main reasons:
# 1. Remove the need for the devs/helpers to ask several questions before we can easily help the user.
# 2. Allow newer/inexperienced ALSA users to give us all the info we need to help them.

#Change the PATH variable, so we can run lspci (needed for some distros)
PATH=$PATH:/bin:/sbin:/usr/bin:/usr/sbin

#Define some simple functions
