Hi all !!

I am using ubuntu 11.04.

By the command : aplay -l | grep card
I got this output:
card 0: Intel [HDA Intel], device 0: ALC272 Analog [ALC272 Analog]
card 0: Intel [HDA Intel], device 1: ALC272 Digital [ALC272 Digital]
card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]

and by the command: lspci -v | less, I get this (under audio device):
Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 06)
Subsystem: CLEVO/KAPOK Computer Device 0770
Flags: bus master, fast devsel, latency 0, IRQ 44
Memory at f0700000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: HDA Intel
Kernel modules: snd-hda-intel


(Dont get the wrong idea, I am a linux newbie, just searched this on google)

I was tinkering with sound preferences, assuming that there would be something like "Reset to defaults" button, but there isnt. Earlier the sound was fine (not great quality, but it was there), but now its gone. I am attaching the status of my sound preference's hardware, input and output tab as a screenshot.

P.S. I know that most probably earlier in the hardware--->Profile option, "Analog stereo duplex" was selected. But selecting that doesnt work now. Also, isnt digital better than analog ? (why wasnt it something like digital stereo duplex, when I seem to have that ability in my sound card ?)

Thanks in advance !!

have you tried restarting pulseaudio?

Thank you for your reply.

To restart pulseaudio, I first did (as normal user, not root):
pulseaudio --kill

and then:
pulseaudio --start

I dont know if it did restart pulseaudio, because it gave me no indication whatsoever. But doing this didnt work. The options in the sound preferences are still the same, and the sound isnt there.

Any other ideas ?

Oh ! I forgot to reply.

Actually that might have worked. Although restarting pulseaudio didnt take the desired effect immediately, after sometime or probably after a logout and login (I dont remember) the sound seems to have been fixed by itself. Well, thats mostly the only thing that counts.

Thanks !!
