Sound Blaster Live 5.1 stops working.

[RoLo]

Hello. I just notice that my card stops working. I have a Sound Blaster 
Live 5.1.
I have tested the next way so I think that the card is still correctly 
installed, so I guess the problem is somewhere I don't know.

rolodoom at rolinux:~$ cat /proc/asound/cards
 0 [Live           ]: EMU10K1 - SB Live [Unknown]
                      SB Live [Unknown] (rev.10, serial:0x80671102) at 
0x1000, irq 21



Then I tested with the next command and actually get sound, but only 
from console, when I open totem, audacity, etc, there is no sound. Jack 
also stops working.

rolodoom at rolinux:~$ speaker-test -Dplug:surround51 -c6 -twav
