Hi,
here is a little guide showing how I managed to make my DVD player silent. No more plane noise.
This has been done on XBMC LIVE using halevt ( http://www.nongnu.org/halevt/ )

Here we go :
1. start a terminal as user "xbmc"

2. Install halevt :

Code:

$ sudo apt-get install halevt

3. Edit halevt configuration :

Code:

$ nano /etc/halevt/halevt.xml

4. replace its content :

Code:

<?xml version="1.0" encoding="UTF-8"?>
<halevt:Configuration version="0.1" xmlns:halevt="http://www.environnement.ens.fr/perso/dumas/halevt.html">

<halevt:Device match="hal.volume.disc.has_audio = true">
<halevt:Insertion exec="sudo /sbin/hdparm -E4 $hal.block.device$" />
<halevt:OnInit exec="sudo /sbin/hdparm -E4 $hal.block.device$" />
</halevt:Device>

<halevt:Device match="hal.volume.disc.is_videodvd = true">
<halevt:Insertion exec="sudo /sbin/hdparm -E12 $hal.block.device$" />
<halevt:OnInit exec="sudo /sbin/hdparm -E12 $hal.block.device$" />
</halevt:Device>

</halevt:Configuration>

5. login as root

Code:

$ su root

6. we have to give halevt daemon the right to sudo.

Code:

$ visudo

7. add this to the end of the file

Code:

### HALEVT-specific configuration ###
# HALEVT
Cmnd_Alias CMDS = /sbin/hdparm # HALEVT
halevt ALL=NOPASSWD: CMDS #HALEVT

8. Reboot and enjoy the silence.
Hope this helps.

I know it is old thread but it this method always worked perfectly for me.
But in 13.10 ubuntu the halevt can not be installed.
did someone managed to install it on 13.10 distribution?
