Could installing without the accessibility profile help?

[Anne Günther]

Hi
Like I wrote before,k I can't reach my sound dialogue in the preferences 
menu. And I also can't change my volume.
So I thought, if I installed karmic without the accessibility profile, 
it could solve that problem. Could that work? I know orca would be still 
available after the installation. Or are there any problems?
