NO sound , NO device , Dummy output stereo

[amanjjain]

Hey,
I have updated my Ubuntu to Lucid 10.04 from 9.10.

Although my sound disappeared in 9.10 only, I thought maybe upgrading might help, but there is no change.

I guess everything is installed fine.
But still
aplay -l command shows "NO sound cards.. "
Moreover the sound preferences shows no hardware, no input and a dummy stereo output.

I have banged my head a lot trying various things written in forums and all but no success.
Can please somebody help me, it would be very thankful.

One more thing : When I test "osstest" , I get sound in both the earphones , but altogether there is no sound. I am very much confused.

Early reply is highly appreciable.

Regards,
Aman

Hey,
I went through the link given on the page
i.e. "http://www.alsa-project.org/alsa-doc/"
it says there you will find your sound card ( chipset ) manufacturer in "drop down" box.

I couldn't find any drop down box over there .. so couldn't proceed forward.

any suggestions??

Can you post the output of these terminal commands for me please:

uname -a
aplay -l
cat /proc/asound/version
head -n 1 /proc/asound/card*/codec#*

Terminal="Applications->Accessories->Terminal"
Please post text output using code tags. Also helpful is the make/model of your PC/Laptop.

i think i know what your problem is... u installed oss v4, after that the sound preferences, that i think they are an alsa component, dont detect ur sound card... it happened to me when i install it for the first time, u have to configure some programs to be able to make sound threw oss, but first try to write in the terminal: sudo soundon

or...
sudo alsa unload
sudo soundon

if that is so run ossxmix (u will only be able to run it if u installed oss...)and u will be able to control the volume from there; i think that ur sound card should be under /dev/dsp now

the problem that u are not getting sound is that u have now installed pulseaudio, alsa and oss drivers at the same time, try running vlc and in preferences audio select oss as output to see if u got sound there.

pd: you can also try to put oss off and reloading alsa as well by :

soundoff
alsa unload
alsa reload

I did a fresh instal 0f 10.4 and am also having the dummy output issue.
Unfortunately I cant use the instuctions in the sticky because I cant find the dropdown.
I am using netbook remix on an acer AspireOne 1410 btw

here are the outputs of the that lidex requested

sudo soundon gave:

sudo soundoff:

And I had just gotten everything working in Karmic when an update screwed everything up and I just decided to do a clean reinstall

I've done these things, hope any of you will be able to assist. I have an Intel DP55KG with built-in optical audio out... so far I have purged alsa and pulse, reinstalled, and verified nothing is muted. Can't figure out what is going on:

Make/Model: Integrated optical audio in/out on an Intel DP55KG motherboard.

When I run:

alsamixer -Dhw

I am able to set all volumes except the SPDIF (which I believe IS the optical audio)... just something I thought was strange, and possibly a pointer to the problem.

Try Fix your sound! in my signature.
Then use Post-Fix your sound! in my signature.
That will update OSS, and it will make your sound work.

I'm having a similar problem in my Dell R14(N4010) running Maverick(10.10).

Any updates on this issue?

Is this an upgrade? Try removing old audio config files.
Using a Terminal="Applications->Accessories->Terminal"

rm -r ~/.pulse ~/.asound* ~/.pulse-cookie 
sudo rm /etc/asound.conf
