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.

HT4623 My iPad 3 has lost the speaker sound after updating to iOS 6.1, headphones are working fine

My iPad 3 has lost the speaker sound after updating to iOS 6.1, headphones are working fine. Please help me out, done all the troubleshooting like restarting, side switcing, cleeaning the headphone jack etc.,

Hi I also have this problem. Sound was only working on the headphones and also on the volume slider in the settings app. Everywhere else I get no sound and no volume slider. Now the headphones don't work either.
(I'm using an ipad 2 iOS 6.1.2)
And NO it's not muted. I've reset all settings and restarted the iPad. Been searching forums for a couple days. Some say its a dirty docking port problem, others suggest a Skype or other app update that could be the problem.
No volume control icon appears when I press the volume control buttons. Only says sound effects, if it says anything at all. Most often there is NO volume icon. YouTube, video, music, and other game apps, no sound.

Poor sound after updating to ISO 7

Poor sound after updating to ISO 7. Before updating i had terrific sound both on my music and videos I recorded with my cam, i had to turn it down. Now, after update, i put volym on Max and can hardly hear the music or whatever. Anyone else with same problem?

I also loved my iphone because it HAD great sound. Since the update of the iso7 for my iphone 4s, i am missing my calls because I cannot hear the phone ringing. The sound is so low even though I have it on the highest sound possible. The is something in the update that caused this problem among others such as the phone blinking out while I am viewing videos. Help Apple! THe battery is going from 100 percent to 20 percent in two hours even when I have almost turned off everything on my iphone. I need my sound back! Apple please find out what happened in your update that caused the loss of the sound!

Why my iPad mini 2 no sound after updated to iOS8

Why my iPad mini with retina display no sound after updated to iOS8

I solved for my ipad mini retina:
- Go to Settings->General
- Change the function of the slider on the side of the ipad from 'rotation lock' to 'sound off'
- Wiggle the slider up and down
- Sound is restored
- You can set the slider back to rotation lock again

I can't back up my phone, they ask me to delete the back up, but I don't want to because I lost everything after updating the iTunes, How can I get back the back up?

Everytime I try backing up my phone, it says there's something wrong and wants me to delete the back up...But I don't want to delte the back up because I just lost everything after updating the iTunes, Is there any way I could get back everything from the back up?

Thank you for answering my question. If I reinstall itune, is it mean that I need to install music, apps, video...everything in itune again? also intall everything in my iphone again?

[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.

How do I recover my lost tabs after updating to Firefox v33?

Problem: After update to v33, I am unable to restore my lost tabs and GROUP tabs from my previous session, which was last night at 6:38 pm EST.
Here are the steps that I have taken:
1) History > Restore previous session is greyed out.
2) I have checked to make sure that I had configured session restore by going to Options > General panel > When Firefox starts: > Show my windows and tabs from last time.
3) I have right-clicked on Firefox > Properties > Previous Versions. But since I never set up any sort of restore configuration, there were no previous versions available.
4) I have tried to look for the sessionstore.js file in my profile folder to replace it with my sessionstore.bak file because the date for that file was last modified at 10/14/2014 6:38pm. However, I can not find the session.js file and the only sessionstore-related files that I see are: session.rdf, sessionCheckpoints.json, sessionstore.bak, sessionstore.bak-20140923175406.
Please help! I had a lot of tabs. I don't want to go to History to find my tabs one by one because I also had GROUPs of tabs that I have not opened in a month or more and each group of tabs have many tabs in them too.

Hi magasx, I'm trying to understand the part about previous.js. That was not helpful because it wasn't an early enough version of your session? In your screenshot it is a very large file, and so is your recovery.js. Did you check the list of closed windows and tabs that appears on the History menu to see whether what you're missing appears there?
Your screen shot shows a 9MB file from March 22nd, it's the last one in the list. To try that file, I suggest copying it to a safe place, and then when Firefox is closed, renaming the current sessionstore.js file to sessionstore.old and copying in the upgrade...js file and renaming it to sessionstore.js. Then when you start Firefox, Restore Previous Session. Does that get you close?

Problem with sound after update

Hello
After update to 11.3 I have no bass sound in subwoofer in Firefox browser (youtube). I uninstall the newest version and install previous (11.2) and bass plays ok.
My os: Windows 7 x64. Sound card Creative X-fi.

Hello!
My problem is summed up in this topic.
Updated Flash Player with 11.3 this morning (june 12th 2012) and since then my 7.1 Sound System works only 2.1. If i enable EAX Effects, works on 7.1 but since it`s just a room it sounds very odd.
I have no problem with sound on HTML 5 websites for that matter, Winamp, Video Players, games.
Uninstalled Flash Player, sounds work ok without it on different browsers, other than Chrome (since it has FP built in).
I hope for a sollution soon.
Thank you.
*edit*
Untill there is a permanent solution, i found a way to deal with my issue and i hope it will help others.
I personally use Chrome and this is for this browser:
1. Type "about:plugins" w/o the quotation in the navigation bar.
2. On the upper right u will see "Details" click it then find the word "flash", and you will see something like this:
Flash (3 files) - Version: 11,3,300,257
Shockwave Flash 11.3 r300
Name: Shockwave Flash
Description: Shockwave Flash 11.3 r300
Version: 11,3,300,257
3. I say again, this worked for me on Chrome. The 3 files i have, two of them are Version 11,3,300,257 and one is 11.2.31.144
4. Simply disable the lates version 11.3 and enable the previous version 11.2
I hope this helps.
