MacBook to TV...audio not working

I have an HDMI cable which works just fine for delivering video from my pre-2008 MacBook Pro to my TV. However, I don't have any audio. I tried a separate optical cable but that didn't work. Any suggestions? Thanks!!!!

For pre 2010 MBPs, audio has to be tapped from the audio output port. You will need a Y connector with a 3.5 mm jack on the single end and RCA connectors on the other end that will be fitted to the audio input of the TV.
Ciao.

Ive just upgraded my late 2009 macbook, and things are not working properly. First of all, when I started the computer first time after installing Mountain Lion, some message advised me that some files were impossible to install.

Ive just upgraded my late 2009 macbook, and things are not working properly. First of all, when I started the computer first time after installing Mountain Lion, some message advised me that some files were impossible to install. Once I wrote my password, and for now on, everytime I start the session, another window advise me that "Java SE 6" is missing, due that, the computer can't run some "CS5Service Manager". If I try to install it, the download ends with an error. If finally, you skip the istallation, you arrive to the dock, but the menu bar at the top of the screen doesn't show up.
In addition, my trackpad doesn't works either. I can move the arrow but i can't click anywhere, probably because the option of clicking by touching is disabeled and I can't performance a regular click.
I'll be very glad if someone know what the heck is happening with my computer. Anyway, I'm going to the genius bar next Saturday. Thx!

We're sorry.
We can't find the article you're looking for.
Please return to the Apple Support homepage.
Sigh.

I have a Serial Number which worked fine on my MacBook Pro but does not work on my desktop PC (Win 7). What is the problem?

You haven't identified the version so I can't tell if offering you contact options for Adobe Support will be of use to you. But they will likely be your only hope of getting resolution unless you just happen to be using the wrong number as the serial number.

Audio not working in Chrome

MacBook Pro Retina mid 2012 8GB NVIDIA GeForce GT650M 1024 MB running on 10.8.2. Latest Chrome Version.
After some period of time (maybe a few days?), sound stops working in Chrome until I shut down and restart the MacBook. When audio stops working, I can copy the URL from Chrome and go to Safari and it works fine. If I shut down and restart, it works fine again in Chrome for a while. Any suggestions on what to do?

Sorry, didn't realize it would be a bother to ask an Apple Support group about this. No worries, I won't be back.

HT201210 AUDIO NOT WORKING PROPERLY AFTER INSTALLED IOS7

After installed ios 7
photos not able to see fully
audio not working properly.... [no treble, no depth in sound, very low soung even the volume is full]
get strucks while playing games

This board is full of people that are update crazy...
even when they have perfectly good working systems.
i know i thought well it's just a security update not a major update.
Best advice... whenever updating the OS, unplug all
firewire devices.
will take note of that from now on.
Was this auto-update? Try downloading the file and
running the update again with all firewire devices
unplugged.
While the 828 is disconnected perform the factory
reset
again.
Disconnect the firewire cable from the 828mkII
-Press the Setup knob
-Turn the Setup knob all the way to the right
-Press the Select knob
-Press the Value knob
-Power off the interface and plug the firewire cable
back
in
-Power the interface back on
i have the original 828 not mark 2, so no reset i know of, just power on off.
After the Mac updates... reboot and plugin the 828,
see if that doesn't get you going.

cheers pancenter, i'll give it a whirl updating without the interface plugged in. thanks for all your help.

how can i transfer my calendar from iphone to macbook? Sync is not working!, how can i transfer my calendar from iphone to macbook? Sync is not working!

If the calendar is connected to a server account, like Exchange, you cannot sync via iTunes. You need to connect to the server on your MacBook.
If it is not connected to a server account then you need to ensure syncing is set up in iTunes. This is in the Info tab for your selected phone in iTunes.

HT2090 my macbook air camera is not working

My Macbook Air camera is not working when I try to use photobooth. I have no problem with google hangouts or skype. How can I resolve this problem?

• Restart your Mac. If the problem continues, use the Disk Utility in your Mac's Finder > Go > Utilities folder to repair permissions. Then test the camera again.
• If the your trouble persists,. reinstall OS X Mavericks. Repair permissions again immediately following the restart that completes the reinstall and before testing the camera again.
• Also check your Mac's  > Software Update... or Apple - Support - Downloads for latest Mavericks updates applicable to your Mac model such as OS X Mavericks 10.9.1 Update.

Macbook 6,1 charger not working

Macbook 6,1 charger not working A1344
The Macbook is a 6,1 purchased in 2010.
My friend has had a go at the shooting suggestions but nothing seems out of sorts beyond it not working properly.
No damage or signs of misuse.
Ordinarily I wouldn't have thought a warranty would still apply but this paragraph on Apple support page made me wonder.
--- Whether your product is in or out of warranty, you can take your adapter to an Apple Authorized Service Provider or Apple Retail Store for evaluation and replacement if necessary. Pending the results of the evaluation, you may or may not be eligible for a replacement adapter free of charge. Signs of accidental damage would negate any coverage. Be sure to bring in the computer used with the adapter; it is required to process potential adapter replacements.---
When my friend took the Macbook and charger into an Apple Store in central London she was told it's out of warranty and best option is to just buy a new one.
Any thoughts regarding whether Apple has approved free replacement for these chargers?
She is in UK but machine was purchased in Australia
http://support.apple.com/kb/TS1713
thanks
Jason

all sorted now - new charger given
turns out a bit of intelligent discussion yielded results
so .. if you have any problem with an older mac take it into an Apple Store
theres an excellent chance they will fix and replace even when the machine is out of warranty

Laptop left Speaker audio not working

Sir,
I have dv-5 1102 tu model laptop, in that left speaker audio not working. But, in headphones & Speakers have no problem in both left & right audio.
Kindly do the needful

Hey @KKVK ,
Welcome to the HP Forums!
I understand your left speaker is not working on your dv5 notebook.
If the headphones are working it would tell us the sound card is fine. The same properties are applied to the speakers and the headphones in your audio control settings.
You could try a system restore to before the issue started to make sure it's not something in the operating system. To perform a system restore see the following guide: Using Microsoft System Restore (Windows 8) or Using Microsoft System Restore (Windows 7).
If this fails I would suggest contacting HP Phone Support to send the notebook for service. Please call our technical support at 800-474-6836. If you live outside the US/Canada Region, please click the following link to get the support number for your region: Phone Assist Worldwide.
Thanks!

Thanks,

you don't have to purchase acrobat pro xi. you can, but you can also use it via adobe's creative cloud subscription service.
to use it via cc, uninstall your current trial.
then go here and log in with the same adobe id used to pay for your cc subscription and start your acrobat xi download, Adobe: Creative, marketing, and document management solutions
