I have installed ubuntu 13.04 and my system configuration is Intel Z77SL-50 \K chipset with intel high definition audio

lspci -v list following as audio device

00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04)
        Subsystem: Intel Corporation Device 2030
        Flags: bus master, fast devsel, latency 0, IRQ 45
        Memory at f7c30000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: <access denied>
        Kernel driver in use: snd_hda_intel

aplay -l list is following :

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 3: ID 2806 Digital [ID 2806 Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Following cards are listed :

cat /proc/asound/cards 
 0 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xf7c30000 irq 45
 1 [U0x46d0x825    ]: USB-Audio - USB Device 0x46d:0x825
                      USB Device 0x46d:0x825 at usb-0000:00:1d.0-1.7, high speed

Now when I insert speakers or use 3.5 jack ear phones I cannot get any sound but if I insert USB earphones I am able to listen to the sound.

Why cannot I listen sound from Analog speakers over 3.5jack?

About pavucontrol:

list OUTPUT devices as HDMI/Display port built in audio.

configuration tab in pavucontrol only shows digital stereo(HDMI) output

one more thing monitor connected to CPU over HDMI.

Try using alsamixer - when you select the sound card, it should have an extra volume control for the headphone jack - i.stack.imgur.com/ZCFMR.png - you might also want to check the auto-mute settings. –  Wilf Dec 21 '13 at 12:41
The kernel did not detect any analog output, and "ID 2806" means that it doesn't know the codec chip. What hardware is this? –  CL. Dec 21 '13 at 13:32
I upgraded to 13.10 and now #aplay -l **** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 alsamixer only show one volume control that cannot be adjusted . output of alsamixer as shown in this image ibin.co/17Lj0ENRwKRR following is the chipset I am using intel.com/content/www/us/en/motherboards/desktop-motherboards/… –  pnitin Jan 1 at 16:59
