hi,

I try changing /etc/PolicyKit/PolicyKit.conf

<config version="0.1">
	<match action="org.freedesktop.Hal.Device.Volume">
        	<match user="sacarde">
               		<return result="yes"/>
             	</match>
	</match>
</config>

or only:

<config version="0.1">
</config>


but error is the same

can you help  me?


thankyou
