Comment 18 for bug 914290

# Here's an improved version of the script which tests every possible model in series trying to make a noise.
# It's improved by using sort -u (which eliminates duplicate values, reducing the number of trials from 315 to 222) and
# having a more conservative substitution, (which only removes and replaces the last line if it already specifies a snd-hda-intel model)
# It doesn't help me, (as none of the models work), but it might be handy for someone else

if [ "$(id -u)" != "0" ]; then
   echo "This script must be run as root" 1>&2
   exit 1
