Something is indee wrong with vol=8, will have a look later:

----------------------------------------
#!/bin/sh
for i in `seq 1 8`
do
  echo "== $i =="
  gst-launch-0.10 -m audiotestsrc num-buffers=20 volume=0.1 ! \
          audio/x-raw-int,width=16,depth=16 ! \
          volume volume=$i ! level interval=300000000 ! wavenc ! filesink
location=volume$i.wav | egrep -o ": level,.*$" | cut -d',' -f7-8
done
----------------------------------------
produces
