No hardware in sound preferences

[lidex]

We're on 9.10 and have and sound hardware keeps on disapearing.

$ aplay -l gives

I have all the suggested applications installed.

What is the output of this command:

sudo fuser -v /dev/dsp* /dev/snd/* /dev/seq*

Try this:

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

Logout/in.

ej my mistake, i was confused by all the audio preset, i initially didnt see the stereo duplex at the bottom of the prests list, so I selected some dolby duplex, which crashed after a few minutes. rebooting and selecting a decent preset makes everything okay. Thanks!

Now run alsa-info script.
Run this command in a terminal:

wget http://www.alsa-project.org/alsa-info.sh -O alsa-info.sh && bash alsa-info.sh

Enter your user password when prompted. Choose the upload option and provide a link for the output.

Thanks for the help!

when I run the second remove statement i get
rm: cannot remove `/etc/asound.conf': No such file or directory

I should add that previously, i made an attempt to solve the problem, I had reinstalled everything alsa, and pulseaudio that was already installed on my system.

Thanks again!

Use nautilus. Go to ~/ (your home folder) and look for anything starting with .asoundrc and delete it. Now reboot.
Next. Using a Terminal="Applications->Accessories->Terminal"
Open this file for editing:

 gksudo gedit /etc/modprobe.d/alsa-base.conf

Insert this line at the bottom:

 options snd-hda-intel model=ref

Save. Close. Reboot.
Check your levels in alsamixer.

 alsamixer

Press <F6> to select the correct soundcard.
Press <F3> to show playback levels. <F4> selects capture levels [or use <Tab>]
Use the left/right arrow keys to select and up/down arrow keys to change levels. <M> to mute/unmute.
Go to "System ->Preferences ->Sound" and make sure the correct soundcard is default and adjust your profile on the hardware tab.
On the output tab choose the correct device.

[dparla]

OK. Update your kernel:

sudo apt-get update
sudo apt-get upgrade

Now reboot so we can work with the latest kernel.
Install alsa backports:

sudo apt-get install linux-backports-modules-alsa-lucid-generic

Reboot again.

I resolved my issue with the code you gave in this post. Thanks!

[dfreelan]

I followed the instructions, there was no (visible?).soundrc in my home folder (so i don't know why it was looking for it) but i ran rm /home/asound.rc, just to be sure.
Also i deleted the pulseaudio backup file i stored in there

I inserted the line of code successfully to the bottom of the file
went to the alsamixer, it appears everything was on full volume, pressed F3, no playback though...

in sound preferences nothing was muted, and the hardware existed (and it exists as analog stereo duplex (1 output/1input))yay!!!

Good news: I can record stuff, the mic input shows it is receiving sound

However, I still have no playback, tried several sound file types. I tried to change the profile of the selected device to other options, but still no sound.

I tried to do research to see if i could find someone else who had the same problem, found nothing

Thanks for the help you have given me!

I ran that link again in case it's useful
http://www.alsa-project.org/db/?f=1f...1a16ae70385749

(P.S.) since my hardware is now showing up, does this actually qualify as a separate issue?

EDIT: also, when i insert my logitech headset, the computer freezes...

[lidex]

Getting there!
Run this command:

dpkg -l | grep "alsa"

If the output shows you have backports installed, please remove it from your system using synaptic. Then follow the alsa upgrade link in my sig to get the full 1.0.23

[dfreelan]

with the steps followed the mic still works, sound appears to have the same situation

When i run alsamixer, it doesnt show up in sound preferences under 'applications', however the "sound recorder" does (EDIT): the sound recorder appears both when recording and when playing what it recorded. Alsamixer shows my card is the one being used

let me know if you can still help or if u can direct me where to go
Thanks again!

EDIT: same problem is resent with logitech headphones, except the computer never completely freezes. justs slows down to the point where nothing opens. Mouse remains active... i dont know if this helps at all >.<

I REALLY appreciate all help

EDIT: next post has more information
