Audio not working suddnely

The Audio System was working perfectly till yesterday. I don't what happened today suddenly the sound stops working. I played a Video in VLC ,by default the audio device which remains selected is "Built in Audio Digital Device (HDMI)" , the sound did not work , only the video played perfectly. Then I changed the audio device to "Built in Audio Analog Device" the sound worked perfectly well if I use my Headphones , but doesn't work when I play it via the speaker. In non-VLC programs (say for example MPD) the audio doesn't work whether I use headphones or I play via the speaker.

speaker-test -c  2 

also doesn't play any sound on both the speakers. i have ensured that the "Master" ,"Speaker" and "Headphones" are unmuted. I tried changing the device number of the card in the /etc/modprobe.d/alsa-base.conf but it is still not working. Can someone please help me out here?

Here are some of the outputs

$cat /etc/modprobe.d/alsa-base.conf

options snd slots=snd_mia,snd_hda_intel
options snd_mia index=2
options snd_hda_intel index=2

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 1: Generic_1 [HD-Audio Generic], device 0: ALC271X Analog [ALC271X Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 2: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

$ cat /etc/asound.conf
# Use PulseAudio by default
pcm.!default {
  type pulse
  fallback "sysdefault"
  hint {
    show on
    description "Default ALSA Output (currently PulseAudio Sound Server)"
  }
}

ctl.!default {
  type pulse
  fallback "sysdefault"
}

Re: Audio not working suddnely

Sony question regarding your speakers: have you checked if they are plugged in correctly?

Re: Audio not working suddnely

I use a mixture of HDMI and audio jack output too. My audio card stopped working last night too. The solution for me was to reboot my computer. An updated had caused some confusion with the audio driver.

Does rebooting solve it for you?

By speakers I didn't mean an external speaker. I meant the built-in one. Sorry for not being clear.

Nope I tried. It didn't work.
