Upgraded to yosemite now my speakers don't work and i can't play videos on Facebook.

When i play a video on face book I'm told i need to upgrade flashplayer, i wasn't even aware i had it downloaded! I have got rid of flash player (i think ) and now I'm told i need to download FP before i can watch videos. I can't play games on FB either and my speakers don't work.
I wish i hadn't upgraded to Yosemite to be honest as i prefer the old layout and it seems to have caused me problems. Everything was working fine before the Upgrade to Yosemite.
Im not good with computer terminology so please reply as simply as possible :-)
Thank you

Try un-installing and then re-installing.

External speakers don't work with Yosemite

I have just upgraded my iMac to Yosemite and now my external speakers don't work.
They are there to be used under System Preferences -> Sound as "Bose USB Audio"
But when I select them I get no sound and "The selected device has no output controls"
I do get sound if I select the Built-in Internal Speakers
The Bose speakers worked fine under Mavericks.
Can anyone help me get them working again ?

Had similar issues with Bose Companion 5 after Yosemite installation. Tried most suggestions posted here without success.
But Birkers' post about plugging in/out analog headphones from Bose puck gave me an idea.
1. Removed Bose USB cable from iMac (Late 2014 Retina 5K / Yosemite 10.10)
- confirm that Bose disappears from Sound panel in System Preferences
2. Played music through internal speakers - OK
3. Played music through 2nd Display speaker - OK
4. Re-connected Bose USB cable to a different USB port
- confirm that Bose appears in Sound panel in System Preferences
5. - Bingo! Sound now playing trough Bose system

EXTERNAL SPEAKERS DON'T WORK

External speakers don't work. They are LABTEC LCS 2420 speakers. The internal speakers with RealTek driver works fine. I have an HP Pavilion 23 touchsmart All-In-One PC with windows 8. I plugged the speakers in the headphone port then tried the audio jack in the back with the same resullt. When I right click on the sound icon and click on playback devices and riight click in the open area i checked show disabled and disconnected devices only the speakers realtek icon appears. Do I need to download other drivers and how should I do this?

Try the following: Control Panel > Hardware and Sound > Manage Audio Devices > in the 'Playback' tab you should see the ports (rear and headphone) > R-Click the one that you are using for your external speakers and make it the default device.
Trust this helps.

My external speakers are not working, any suggestions?

My external speakers are not working, any suggestions?

try different audio or USB cables.
try the speakers with a different computer.
go to the speaker manufacturer's website and see if there's some troubleshooting info or a new driver that you need.
check System Preferences > Sound > Output
see if the speakers show up in the sound output device list
make sure the mute box is unchecked.
Check Applications > Utilities > Audio Midi Setup
see if your speakers are selected in the column on the left
make sure the mute box is unchecked

External speakers don't work with Maverick

My external speakers will not work in Maverick....internal speakers ok. Tried rebooting, unplugging external speakers from back of computer, etc.......going to "sound" in System Preferences, only "internal speakers" is listed. Had external sound PRIOR to Maverick.....

Boy, do I feel like an idiot !!! I had the speakers plugged into the input RIGHT NEXT TO the headphone port !! I could have sworn that's where I unplugged them when I did some "housekeeping" on my desk ! I even labeled that port "speakers"............I must say though that the"output" in "sound" in sys. pref. NOW SHOWS UP AS HEADPHONES !! So SORRY for taking up your time, but you got my external speakers working, and for that I am VERY grateful !! I guess in all your experiences you've seen it all, but................THANKS AGAIN !!!!

After upgrade to Yosemite 10.10.3, IPhoto not working

After upgrade I am not able to import photos from my Kodak M1093IS camera. When I connect the camera, and click on import photos I get an error msg saying .jpg is not the correct format. I had no trouble importing from this camera before the upgrade - Help!
Steve

Use Image Capture to try to upload the photos to a folder on the Desktop. If you can see if you can import them from there.
Does the camera have a memory card? If so, once you've off loaded the photos use the camera to reformat the card. Take some test shots and see if iPhoto will recognize and import now.

After upgrade to os 4 some apps don't work including Apple Store

Upgrade went ok, but took long time. Some apps don't work correctly or crash. e.g. Apple Store app just recycles back to main screen. Starbucks app works for a few seconds then crashes.

I had same problems.
I decided to "downgrade" back to OS3. You can too!
Go to this thread and read about it. http://discussions.apple.com/thread.jspa?threadID=2473976&tstart=0

External speakers don't work on iPad mini

My speakers won't work with my iPad mini. They worked fine last week all of a sudden they stopped working. I tried Headphones those don't work either. Is there a setting somewhere that I can use to fix this?

I had the same problem.No sound on Head phones all of a sudden. Restarted ipad mini. Didn't work. Changed all volume limit settings. Still didn't work. Restarted again. I can hear the sound in head phones again now.

External speakers no longer work with airport ---- what gives please help

Itunes 8.2 no longer shows the drop down menu where I can choose 'computer' or 'external speakers'. I've used this feature for years, and now, it's gone. Where'd it go?
There is a green light on the Airport. The 'Look for remote speakers connect with AirTunes' is checked. The Imac is reading the wireless network. The external speakers are connected correctly.
Where the heck did it go....and more importantly, how do I get it back?

After upgrading to yosemite, my Cintiq lags when using photoshop, any fixes?

I've upgraded my iMac to Yosemite and photoshop CC 2014 lags when using my wacom cintiq. So far these are the steps I've taken.
I've installed wacom drivers from nov 2014 because the jan 2015 drivers didn't help
Doesn't seem to be a ruler issue within photoshop
I've renamed my adobe photoshop prefs file
and running osx 10.10.2

Not true. iCloud still works with Mavericks.
What browser are you using?
It would help to give us more information. You can download Etrecheck, which is a small free app which will generate a system report on your mac and you can paste the report here in a response. http://www.etresoft.com/etrecheck
Have you used any "maintenance" or "cleaner" apps like MacKeeper or CleanMyMac in the past?
Do you have third-party antivirus software on your Mac?

Library not found after upgrading to iTunes 7, old libraries don't work

For the second time since iTunes 7 was released, I've been asked to upgrade and did so without issue on the first day of upgrading. When I shut my computer down and came back the next day, however, the library is not found when I attempt to launch iTunes. Before, I simply reverted to iTunes 6 and copy/pasted a "previous library" as the current library. Now, though, I have a new iPod and it needs iTunes 7 to run. I've tried copy/pasting a previous library to the iTunes Library folder with no luck.
90% of my music is in the .m4a format so I need iTunes to listen! Not to mention, I need it to update my brand new iPod. I really need help on this, can someone give any advice? Thanks in advance.

johnc86,
Are you following the instructions from this article in the Apple Knowledge Base, in particular the renaming of the .itl file from the Previous Libraries folder?

RE: External speakers don't work while watching DVD on MacBook

Hello, I have a late 2006 white 13-inch MacBook. I have been trying to use an Altec Lansing external speaker while watching a DVD movie on my Mac, in order to increase and improve the sound, but when I plug the speaker cable into the headphones jack on my Mac, no sound comes out of the speaker. The speaker works fine when I plug it into the same jack to listen to music in my iTunes library, so I know the problem isn't with the speaker per se.
Can anyone tell me how to fix this problem? I have tried to play around with the Sound on System Preferences and with the Audio MIDI setup but I'm not sure which setting is at fault. Thanks very much.

Hi, thanks for your response. When I got into Preferences>Disk Setup, under Audio Output, "System Sound Output" is selected (there are no other options listed). Also, "Disable Dolby dynamic range compression" is checked.

Old G4 Mac external speakers don't work with Mac Pro - Please Help

Does anybody know if there's an adapter, so I can use the old clear plastic orb speakers that used to work with the old G4s with my new Mac Pro? Thanks.

Hi-
The Apple Pro speakers only work with a special jack available on some G4 towers and iMacs.

Time for new speakers.
