I've managed to loose the sound function on my acer 5050 aspire.

There was sounds but the power cord came lose and it powered off unexpectedly and now I can't get it back. Please help.

When I go to sound preferences and then the hardware tab there is no sound hardware detected, but the command

aplay -l

gives the result:

**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: ALC883 Analog [ALC883 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: SB [HDA ATI SB], device 1: ALC883 Digital [ALC883 Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0

So what gives?
