audio card profile not saved

[clamaver]

Expected behaviour

When a audio card profile is selected, in hardware tab, in mate-volume-control, the profile should be saved, even after system restart.

Actual behaviour

The profile is changed in the current session. But, after restart, other default profile is set.

Steps to reproduce the behaviour

Enter the sound preferences applet. Hardware tab.
Select other profile, different than default.
Restart the computer.
Check the profile has not been saved.

I have "solved by hand" by adding a line to etc/pulse/default.pa
But this may be automatic.
