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?
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.
