Sound is working only on the left side, when I open the sound configuration tool there is no hardware there but if I run lspci -v | grep -A7 -i "audio" I get this output:

00:05.0 Audio device: nVidia Corporation MCP61 High Definition Audio (rev a2)
    Subsystem: ASUSTeK Computer Inc. Device 8290
    Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 22
    Memory at dbff8000 (32-bit, non-prefetchable) [size=16K]
    Capabilities: <access denied>
    Kernel driver in use: HDA Intel
    Kernel modules: snd-hda-intel

I can see that the system is using the Intel HDA driver but the hardware listed is the nVidia MCP61 High Definition Audio. I wonder if that is the correct driver for my sound card. Is it because I am running on 64bits?

This is the output of sudo aplay -l

**** Lista de Dispositivos PLAYBACK Hardware ****
placa 0: NVidia [HDA NVidia], dispositivo 0: ALC662 rev1 Analog [ALC662 rev1 Analog]
  Dispositivo secundário: 1/1
  Dispositivo secundário #0: subdevice #0
placa 0: NVidia [HDA NVidia], dispositivo 1: ALC662 rev1 Digital [ALC662 rev1 Digital]
  Dispositivo secundário: 1/1
  Dispositivo secundário #0: subdevice #0

There are 2 devices there, 1 analog and 1 digital. Does that mean there is a conflict???

My aplay -l output is similar (although different hardware), but I have the hardware in the sound configuration tool. I don't think there is a conflict, might be a driver issue. (pastie.org/2799806) –  lgarzo Nov 2 '11 at 16:51

Most likely you just have a faulty plug on your sound card. Can you test it in another computer or SO?

Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. –  Marco Ceppi Nov 3 '11 at 2:37
    
I agree with you but in this particular case the essential is that the problem may be a hardware failure and the link is of a discussion of people with the same problem and ending with this conclusion. –  desgua Nov 3 '11 at 9:47
