problem with orca and sound after installation

[Simone Dal Maso]

Hi,
I installed Ubuntu 6.10 just yesterday.
I made it alone without problems, using orca in conjunction with my display 
braille mdv mb408s, supported by Brltty.
So now?
The problem is that I've no more any sounds!
The first time I rebooted the pc I hear a little sound from my sound blaster 
live, then I login into ubuntu and Orca starts properly speaking.
But now, all sounds are mute!
So I tried to open a console and digit:
asoundconf list
to see if there are more than 1 audiocard installed, but the system tells me 
only the word "live!" That is my sb live.
Is there a mode to check volumes?
I can use only display braille in text mode or with some difficult also in 
gnome environment but without voice, so... if there are commands that can 
check and modify volumes please tell them to me!
Thanks in advance.
