We did the same and it's working OK here :-)

It's just a test if lame is executable at all. In fact lame is executed
twice by liveice.

If you look carefully at your strace output, you will notice a failing
setpgid() call. This patch worked for me:

        if(g_conf.frontend==FE_NONE){

<p>This is my command line:

#!/bin/bash

USER=`whoami`
CONFIG="/etc/liveice/$USER.cfg"
R="/home/www.scram.fm/mitschnitte/`date +%Y%m%d_%H%M%S`.mp3"

udo /usr/bin/screen /opt/liveice/liveice -F $CONFIG -R $R -V

"-R" is yet another parameter added by me to control the remote dump file.
