On the server the volume control is working, but 
I can't use the volume control on the thin clients (feisty installation, with some add multimedia progs)


Meanwhile I managed to increase the sound level on the thin clients. For that I used he command amixer. 

I did the following steps:

1.) SETUP THE MASTER VOLUME INSIDE OF THE USER SESSION:

1.1) replace the file /etc/X11/Xsession.d/80_ltsp-sound with:

<snip>
#/bin/bash	
THINCLINET_MASTER_VOLUME_LOCAL='85'
echo "if [ -n \"\$LTSP_CLIENT\" ] ; then
	/usr/bin/asoundconf set-pulseaudio
	/usr/bin/amixer set Master ${THINCLINET_MASTER_VOLUME_LOCAL}% || true
else
	if ! type pulseaudio >/dev/null 2>&1 ; then
		/usr/bin/asoundconf unset-pulseaudio		
	fi
fi
</snip>

This script also solve this bug: * https://bugs.launchpad.net/ubuntu/+bug/105709
*


2.) SETUP THE MASTER VOLUME DURING THE BOOT PHASE OF A THIN CLIENT:

2.1) Save the following file to /opt/ltsp/i386/etc/rc.setup_localsound

<snip>
#!/bin/bash
THINCLIENT_MASTER_VOLUME='90'
				
[ ! -c /dev/dsp ] && echo "Can't find sound card, /dev/dsp is missing. Continuing."
amixer set Master ${THINCLIENT_MASTER_VOLUME}% || true 
</snip>


2.2) give the right permissions
chmod 755 /opt/ltsp/i386/etc/rc.setup_localsound

2.3) add this line to /opt/ltsp/i386/etc/lts.conf
RCFILE_01 = "/etc/rc.setup_localsound"  *
*


Until now, this lines works for me, but I am still curious why the volume control on the gnome panel, doesn't work if you are using a thin client? Any answer on this?
