Problem of no sound

[raymano9]

Dear all,

I am new to ubuntu and i am facing problem of no sound. Initially when i installed ubuntu, i do not faced the issue of no sound. I can hear all the sound including the sound of ubuntu normal start-up sound. No problem with totem movie player too.

Out of a sudden i faced the problem of no sound. Not a single sound in all aspect. Is there anyone out there who can help me?

try opening a terminal and post the results of this command
aplay -l

also, check and make sure your sound isnt muted.

[raymano9]

thank you for your suggestion on the terminal part but it still does not work ....

how to make sure my sound is not mute? I use normal notebook keyboard to turn on the volume to the max .... still cant hear a single sound ...

[halitech]

what was the result of running the command I gave you? did it give you any information back or did it just drop a line?

[raymano9]

what it means is that Ubuntu is seeing your audio hardware and you are using an Intel chipset which I have not seen good things about. Usually, from what I've seen it involves removing ALSA and reinstalling it. Before we go that far, try the instructions on this page

I just read the link you gave me, following are they writes:

I solved this problem and I get all sound out!!!

I found the solution occasionally.

It is that you must first select "external amplifier"(listed on the volume panel) and unselect it right away.

It make me feel very strange why have to do it but it does just work.



Where can i find the volume panel?

did you follow the instructions in post #2?

I see that, not sure why its not giving the other options. I'd suggest reading further down the page and see if anything else helps.

This may or may not be your problem, but Pulse Audio seems to give people problems and interferes with otherwise working settings. You might try to go to System>Preferences>Sound and make sure that you correct sound device is listed. If it is, try using Alsa only settings by going to System>Preferences>Sessions and UNCHECK Pulse Audio. It has worked for others, and allows the system to use Alsa as the only system sound configurator.
