Try going into your settings and 'reset all settings'
You will need to retweak your device but it's been said to help with sound issues.

There was add one and i lost it after the update and i don't remember it's name

there was add one and i lost it after the update and i don't remember it's name
it was add-on to show me the source of any click able content
like pics on twitter or Facebook
also the videos on youtube
and it showed a little icons with small pic shape on it with different colors
and also sometimes with a small lock shape on it
now i need to know what this add -on name or how to get it back

Add-ons are not auto-deleted as far as I know...
It's possible that the extension or userscript simply doesn't work correctly in Firefox 22 due to a change in Firefox. If you look at the add-on pages, often the reviews will mention whether the add-on is broken in a new release.

[SOLVED] Lost Sound After Upgrade

Solved (for now at least). The problem appears to be a bug with alsa. Alsaconf writes a file called /etc/modprobe.d/50-sound.conf, which contains the aliases for the sound card. But for some reason it then wasn't reading the file. Copying the alias entries to /etc/modprobe.d/modprobe.conf to read directly from there seems to have worked.
Now to fix the frequency scaling.
===================== solved ===========================
I lost all sound after the last upgrade. I just rebooted because frequency scaling is also not working, and no sound.
all drivers seem to be there:

I tried firefox, xine, mythfrontend, avidemux2, xmms and mpg123 - there's no sound in any app. If I play something where there are indicators, like in xmms, the eq indicator levels jump, the song progresses like it's playing, but no sound. I reran alsaconf, it seems to be configured properly. The mixer sliders work and aren't muted. It doesn't work either as root or as user.
I have another computer hooked up through the line out and the sound still works fine there, so it doesn't appear to be a hardware problem.
I'm completely stumped at this point. If it's a bug somewhere, what's it a bug in to cause global sound loss? Is there anything else I'm overlooking? All I can think is that it must be muted somewhere, but I can't find it. Or else it has something to do with the cpu and cpu freq scaling that's also broken now.

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
Check your settings. The iPads have a small switch on the right edge. It can be used as a rotation lock to keep the screen from automatically reorienting itself as you move around, but you need to have the tablet’s settings configured properly. That same switch, right above the volume buttons, can also be set to function instead as a mute button to silence certain types of audio.
If the switch is set to work as a mute button, you can change its purpose to “screen-rotation lock” by tapping the Settings icon on the home screen. On the Settings screen, tap General on the left side, and on the right side of the screen flick down to “Use Side Switch to.” Tap to select Lock Rotation or Mute to set the button’s function. Even if you set the side switch for your preferred use, you can still mute the Mini or lock the screen. Just double-click the Home button, and when the panel of apps appears along the bottom edge of the screen, flick the row from left to right with your finger. Tap the icon on the far left side of the row to either lock the iPad’s screen or mute the iPad’s alerts, notifications and sound effects. Music, podcasts and video are not muted unless you turn the volume all the way down.

"Dirty" sound after Kernel update. [SOLVED]

First of all my sound have always been "dirty" on Linux, like if the speakers/headphones where broken. However, earlier today I configured my sound for the first time on Arch and had a terrific sound! Perfect and clear. However, after I updated, my sound configuration was messed up and now, after re-configuring it, it has this "broken" sound again. Anything I can do about it?
/Richard

So I won't have to re-configure the sound again if I get kernel -8? Like 5 minutes after I got kernel -7 I saw there was a new update but with my recent problem with kernel -7 kept me from updating. My sound works almost perfectly it's just that there's this tiny buzzing sound in the background all the time.

I have no sound after HP update. please help

I have no sound, it states " no audio output device is installed"

Renia,
Apparently the issue is not on the list of issues that test program can detect. Sometimes it works -- this time it could not see the problem.
Try this:
Perform the Hard Reset . Boot the computer and log in
The procedure will not wipe out your data -- this is just a driver refresh to force the computer to read the drivers and software from the Operating System that is installed on your computer.
That may do it.
===========================================================================================
You said the problem arose after an Update. You can try "going back in time" to when the sound worked:
Restoring Windows to a Previous Point (Windows 7
Using Microsoft System Restore (Windows 8)
System Restore sometimes works better if you first drop the system into Safe Mode:
HP PCs - Windows 8 Safe Mode
===========================================================================================
You may have to resort to uninstalling and then reinstalling the audio driver.
Control Panel > set icon view > Open your Audio > right click on your audio driver > select Uninstall
Restart the computer and log in. As you do so, the driver will reinstall itself.
More tips are outlined and explained in the guides provided earlier.
Kind Regards,
Dragon-Fur

HT201272 Lost apps after software update

Has anyone lost apps when they downloaded the new software? I had a magazine subscription which I now don't have since updating my iPad.

They should be in the iTunes library on your computer. Connect the device and sync what you would like to the device.
The only time I've heard of apps not re-appearing on a device after an update is when a user interrupts the upgrade process. Have you tried a restore of the device using the backup created just prior to the update?

[solved] Typing error sound - after last update

Hey guys, after last update every time i make some mistake while typing on console (rxvt) or at the file search on gnome, this weird sound comes out from pc speaker (some eletric bizzz). I can't find anything related to this, does anyone knows if that is some kind of configuration of Xorg or it's a bug?

Lost network after kernel update

Hi,
I'm just reporting that I had this issue today too. I rebooted my computer from Win7 to Arch64 and I was left without network. Also it doesn't work in windows after rebooting back. I thought that It is something with connection so I tried to recoonect cable and also tryied to swap it in switch/adsl gateway. It started working after several switches (not on 1st!) It looks like interface is repeating on and off. So I rebooted to Arch and it stops working again...
I fixed it by reinstalling kernel26 package. But it is strange because it works yesterday, last thing what I did with kernel and modules was update of gc nvidia drivers... I don't know when I updated kernel last time
I'm using same network driver as Karol - r8169
lsmod | less
mii 3826 1 r8169
I'm using this card as well. I upgraded yesterday and I can't get wireless with WICD. Windows and normal network daemon work fine. I use kernel26. What other info can I provide? If a bug report needs to be filed, would it be WICD, kernel26 or other?
Also, I forgot, but I'm not using normal Wicd, I'm using wicd-nogtk from AUR. Krychle, are you using this also?
Edit: I think this has to do with the python update. I updated wicd-nogtk and its good now. I am online.

Lost Everything after transfer/update

I cant find any of my recently bought apps/songs after recently updating my ipod to a new computer after the old one crashed. When transfering there was a button that asked about transfering music and losing purcahes. I didnt read it carefully and clicked continue. Now everything is gone and I cant seem to find purchases anyway. I was wondering if there is anyway to get this stuff back?

Lost sound after updating to Mac OS 10.4.9

Hello everybody
I just updated from 10.4.8 to 10.4.9 and after rebooting, when I opened iTunes to listen to some music I realized there was no sound. I then checked in the Sound panel in the system preferences and the control panel does not recognize any device.
Any suggestions on how to solve this?
Thanks in advance.

That's right, I updated using the automatic software update... I thought doing so was safe, so I'm a bit dissapointed, this kind of thing should not happen...
I'm downloading the combo... Hope it helps.
Will notify if the problem is solved.
Thanks again.
