I have the same problem in Windows 7 and Ubuntu 10.04 where I can't record "what I hear" or "Stereo Mix" or "loopback", etc...

I did not have this problem in previous versions of Windows (XP) and Ubuntu (9.04)...

I hope this isn't because of MPAA/RIAA/DMCA/ACTA crap!

What is it you are recording from and what program are you using to do it?

Bash script
will record all sound produced by your system, and save it as a wav file

#This script require sox
#sudo apt-get install sox

if [ -n "$1" ]; then
OUTFILE="$1"
else
TIME=$(date +%d-%b-%y_%H%M-%Z)
OUTFILE="recording_$TIME.wav"
fi

# Get sink monitor:
MONITOR=$(pactl list | grep -A2 '^Source #' | \
grep 'Name: .*\.monitor$' | awk '{print $NF}' | tail -n1)

# Record it raw, and convert to a wav
echo "Recording. Ctrl-C or close window to stop"
parec -d "$MONITOR" | sox -t raw -r 44100 -sLb 16 -c 2 - "$OUTFILE"
