Getting sound from macbook to work on HDTV

Hi, I'm having problems getting sound from my macbook aluminum 13" to my tv. The tv is a Samsung R8 Series 37" LE37R87BD HD. i got picture up by running a dvi to hdmi to the tv. i have no problem with picture but i can't get any sound. I tried 3.5mm jack from macbook to tv 3.5mm jack. got no sound. so bought a 3.5mm Jack to 2 x RCA and still got no sound. i even ran the the jack through my home cinema system and to no luck.
is anyone else having this problem and is there a solution?

Forgive what may be a dumb question on my part, but you are using the correct audio jack on your MacBook? The output would be the one closest to the security slot, farthest from the display/USB ports of the two 3.5mm/optical jacks. Also check the Output tab of the Sound system preferences to make sure that the Headphones/Line output is selected. It will probably be the only output shown, but double-check just to make sure.
Note that not all TVs will work with an auxiliary audio input when the video input is set to HDMI. Check your TV's documentation to see if it can split the video and audio input to different sources. That wouldn't, of course, explain why your audio amplifier isn't getting signal either.

Getting sound from Mac to Vizio TV

I use a 2008 Macbook Pro with a 17 inch monitor and using OS X 10.5.8. I am connecting it to my Vizio 47" with a DVI to HDMI cable. The connection works fine. That is, the dispaly works just fine.
I'm having a sound problem. I have connected my computer to the TV with a jack from the headphone jack on the computer to to the audio jack on the back of the TV. No sound. The cable works with external speakers (again from my computer to the external speakers).
On system preferences I have gone to Mac Help for "Changing your computer's sound device output. Among other things, the help box says, "To listen though your display's built-in speakers, select Display Audio." Of course, my TV has built-in speakers, so I'm wondering if I need to make a selection like that. If so, that's problematic because my System Preference give me only one output option: "Headphones" bulit-in output.
Any suggestions on how to get sound from my computer through the built-in speakers on my Vizio TV?
Thanks in advance.

First of all, in your version of the MacBook Pro, sound is not transmitted through the HDMI connection to your TV. So, you're right, you have to go through a jack from your mini-stereo plug to your TV's speakers (or an amplifier, or external speakers). There is nothing to do about that.
The sounds output should be through "Headphones", because the Mac can't tell what's plugged in there. The sound won't go through the "Display Audio."

I've connected my ipad to my TV via hdmi but cannot get sound. Is there a way to get sound from the TV?

Supports multi-channel digital audio output on compatible devices
make sure your ipad is not muted
make sure you volume is not all the way down
make sure audio play out of the ipad when not connected to the hdmi adapter
if you did and it don't work then it's likely an issue with the connetor
or the tv or it's settings

Can't get sound from my midi channels

Hello. I've been using Logic 8 for a while. 2 days ago I updated to the newest version 8.0.1 and after I did it, I can't get sound from my midi channels. Before the update I could use my Ivory pianos perfectly, but after the update I can't. I've tried every setup I can imagine. I've been here sitting for hours trying to fix it but I can't .
Logic recognizes my keyboard, since I play...all the notes appear on the transport bar, but i can't get sound from any sampler (Ivory, EXS, EVP88, etc).
I've checked my outputs, etc...but nothing.
Please help me!!! I'm desperate!
Thanks

Do you hear the Audio tracks and only Software Instruments are not working od don't you get any output at all? I was just assuming that through the update your Apogee has been removed as your Audio device in Preferences->Audio->devices.

Can't Get Sound from Harmon Kardon Soundsticks External Speakers

My Soundsticks have worked fine on my eMac and iBook bow I can' get sound from them. The System Pref has only "Internal Speakers" as an output option. I've zapped the PRAM and fixed permissions with no luck.
What am I missing? They have worked before and all connections from speakers to the iBook headphone jack are fine. Earbuds work.
Any and all help is appreciated.

Do the speakers still work with the eMac?
Have you tried resetting the PMU?
Are you saying that earbuds work with the iBook, while the speakers do not? How can that be if the only output option is listed as internal speakers?

Can't get sound from Insignia BT headphones w/ BT-equipped dv3t

Both are brand-new, I charged the headphones and downloaded the updated drivers from www.broadcom.com (actually Vista seemed to do it automatically) and the device is paired but I can't get any sound out of it (it's turned on:-)).
Under the Playback tab in the Sound control panel there are three items:
Speakers: Bluetooth Hands-free Audio
Speakers and Headphones: IDT High Definition Audio CODEC
Independent Headphones: IDT High Definition Audio CODEC
All say they are working, but when I test the sound of each one I only get sound from the notebook speakers using the second option. The only weird thing I can think of is that I had the USB adapter plugged in when I downloaded the drivers, so maybe it downloaded drivers designed to work through USB? (I can't get sound with the adapter plugged in, though, either).
Any suggestions welcome, I really want to get this to work and not have to send the headphones back to seller (which is what Insignia tech support told me to do).
P.S. I know I have BT turned on because I'm also connected to a wireless home network, they go together.

Hello again,
oops, I must have missed your last message... sorry for that!
I have to say, that I don t have my digital sound system that long, that I can answer this question for sure. However...
You re right, that it should be possible, although I wasn t able to find a way to do that... yet... Somewhere (don t know if it was this forum or another place) I ve read, that the SPDIF support for Windows Vista isn t that nice at this time... perhaps a new driver will solve this
Furthermore... I don t use the Media Center that much. So I don t even know if there is any option to set the output device (within the application Media Center). That would be important to realize "the best of both worlds". Explanation: If you want headphones support, you (always) have to leave the Speakers device as default. Other applications (such as Winamp,...) allow us to set the output device (in Winamp for example you can set it under the preferences Output -> Directsound device) to the SPDIF device, although we have selected "Speakers" as default in the control panel... nice, isn t it's For sure... if it would work...
That way you don t get a(n) AC3/DTS signal via SPDIF... so, if you use Windows Vista (I can't answer your question related to other operating systems, because of my newly purchased system -> I haven t used it on XP) the only way that I know ( til now) is to select the SPDIF device as default...

Only sound from the external speakers. Any help would be greatly appreciated.
If you getting sound from the external speakers....are we talking the ones on the laptop?
Means you still have the onboard sound turned on at a guess.

This worked for me as well. Great find! I have gigabyte ep45-ud3r motherboard and I was getting all sound through external speakers except itunes was playing the sound out of the digital output instead of the speakers. I could see this when I went to control panel > hardware & sound > manage audio devices. I did the repair as described above and now I have sound in iTunes.

IPod touch audio issue: why do I only get sound from one channel in my ear-pods?

After upgrading my brand new iPod touch 5th generation to IOS 6.1.2 I only get sound from the right channel of my ear-pods.
I did not have this issue with IOS 6.1.1. Is this a problem derived from new IOS? Any idea on how to solve it?
Appreciate your help!

Have you tried other headphones? If you confirmned it is an iPod problem:
- Try cleaning out/blowing out the headphone jack. Try inserting/removing the plug a dozen times or so.
Try the following to rule out a software problem
- Reset the iPod. Nothing will be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup
- Restore to factory settings/new iPod.
- Make an appointment at the Genius Bar of an Apple store. Seems you have a bad headphone jack.
Apple Retail Store - Genius Bar
Apple will exchange your iPod for a refurbished one for this price. They do not fix yours.
Apple - iPod Repair price
A third-party place like the following will replace the jack for less. Google for more.
iPhone Repair, Service & Parts: iPod Touch, iPad, MacBook Pro Screens
Replace the jack yourself

Hi,
Try the following.
First, download the Flash uninstall utility on the link below and save it to your Desktop.
Flash Player Uninstaller.
When the download has completed, close all browser windows and run the uninstaller. After this has completed, restart the notebook.
Next, download and install Firefox and then using Firefox, download and install the latest version of Adobe Flash.
Close all browser windows before running the Flash installer.
Launch Firefox and see if Youtube videos etc play Ok - if they do, close Firefox, open IE and click on the same Adobe Flash link above to get a prompt to install the ActiveX component. When done, restart IE.

How do I get sound from external device into my iMac?

Hi there, I am trying to get sound from a Pioneer DJ mixer which has standard RCA outputs into my my new 21" iMac. Typically in the past I would get a converter from RCA to 1/4" stereo jack and plug into microphone input, how simple. Now Apple has changed the set up and have no idea as to how to get sound in. The headphone jack in the back of the iMac will only take sound in from earbud microphone, other than that it will only be for sound output. Any help would greatly appreciated.

do i need to transfer the midi region to the audio region to hear the play back.
If you need audio monitoring of your device the "Software monitoring" in the Logic Preferences must be enabled. You can switch on the Audio Track monitoring button (labeled as "I" at the bottom of the channel strip).
ive tried recording the keyboard audio thru and audio track it works just cant quantize it like u said and i think ive already tried it before but ill give it a go again
This is wrong conception. To be able to quantize or do any processing like that, you need to record your performance using a midi track in Logic.
1. I hope you have created some Multi or Standard Instrument so you can edit (quantize) the midi region etc. When you decide that your midi work is O.K you can record it as audio using the Audio Track you are talking about.
2. The other way (new one) is to use the "External" plugin inserted on a Software Instrument.
This way combines midi and audio i.e you record/draw the midi on the Software Instrument track and is outgoing from the Software Instrument channel strip. In this method you must use "Real Time" bounce cause you use external midi device.
3. If decide to use the second method you can bounce the audio but you also can record the audio on an Audio Track if route the Software Instrument to a Bus and assign the Audio Track "Input" to record from that Bus.
