No audio in an external speakers.

I am connecting MacBook Pro to a flat screen TV, using DVI/HDMI cable. I am getting good video but no audio. In the system preferences/Sound/Output, the only option I see is "Internal Speakers". How do I get audio from the TV speakers?
I appriciate your help.

To my knowledge the Displayport to DVI adaptor does not carry sound.
Your best bet is to run audio out from your mac to the TV's audio in.
note that this can be either analog, or optical as the ports in newer macs combine both functions.

Lion audio dropouts with external speakers?

Since I installed OS 10.7.3 (upgraded from 10.6.8), I get audio dropouts whenever I use external speakers. I use my Mini (purchased a year ago in Feb 2011) connected to my TV for Skype, Netflix, and listening to iTunes, so this effectively eliminates my ability to use it. I don't get dropouts if I use the internal speakers, and it doesn't seem to matter whether I'm using iTunes to play something resident on the internal hard drive or watching something on Netflix streaming over wifi, or whether I have wifi or bluetooth on or off. The external speakers are run through an HDMI cable connecting the computer and the TV.

Updates applied, at least one of which caused reccurrence of my audio dropout problem (I'm guessing iTunes is the culprit):
iPhoto Update 9.2.2
GarageBand Update 6.0.5
Digital Camera Raw Compatibility Update 3.10
Application Loader 2.5.1
Safari 5.1.4
iTunes 10.6

Audio Pop to External Speakers

Hi,
When I have my MacBook plugged into external speakers I get a random "pop". Its usually when I have had iTunes playing for a while and close iTunes to go to something else. Sometimes it pops, sometimes it doesn't. I've tried it on different speaker, and have heard it on other speakers.
I've read that their was an audio update for 10.4 with regards to an audio pop when going into sleep or shutdown, is their any patch for 10.5? Has anyone else had my described problem? Is it normal?
Respectfully,
AJ

T520 audio output to external speakers

I am trying to connect my new T520 to the external speakers I had used with my deceased desktop, and I don`t want to cause any damage!
The speakers (subwoofer and 2 small speakers) were connected to a lime green jack on my desktop. My question: can I use the earphone jack of the Lenovo for that connection ? I assume so, just want to make sure...
BTW, the sound coming from the portable is simply abysmal....
Solved!
Go to Solution.

Yes. You can plug the green speaker plug into the headphone/audio out jack. It will work fine.
You can adjust the volume of your speakers in Control Panel>Hardware and Sound>Realtek HD Audio Manager.
Let us know if you have any other issues.

Need Audio Help - USB External Speakers

This should be fun!
Need Audio Help! My USB external speakers are recognized in Garage Band Preferences, but NOT in System Preferences. (I use the audio interface, US-144 Tascam)
Which means:
I can only play my speakers using Garage band and not iTunes.
They were working in both iTunes and GB many times before.
I see that others have had problems losing their external speakers after updating their iMac.
I've called Apple for assistance (no help)
Changed the order of connections
I've shut down again, again...
Help please

Open System Preferences/Sound and select the USB Speakers as your Output device
If that doesn't do as you expect, or you need to tweak them, run Utilities/Audio MIDI Setup and select them there then adjust the Format and Volume etc.

No audio output from external speakers

can hear through ear buds but not through the external speakers
anyone had similar problems and can advise please

I bought my iPhone 3G Sept 28th. Up until a few days ago, I was able to play the Ipod through my the external music speaker on the iPhone. All the sudden the music stopped playing through the external speaker. The only way I can now listen to music is to plug in the earphones.
I've tried plugging and unplugging the earphones about 10 times, resetting the iPhone, resetting the iPhone through iTunes, blowing out the headphone plug with a can of air, etc. Nothing is solving the problem.

Dull audio quality in external speakers

I purchased HP Mini 110-3606tu. Installed Windows 7 starter edition. Installed all drivers from www.hp.com.
The inbuilt speakers have quality audio output, but headphones which i connect produce sound as if some low pass filter is applied on the sound before outputting. I goggled about this on internet and found a solution on ehow.com but that site says that audio drivers for XP have this problem. If I install audio drivers meant for vista this problem will be solved. Although i already installed drivers meant for windows 7 still i gave it a shot.. But Vista drivers wouldn't install. Somebody please help me on this!!

Have you tried installing this Audio driver which is for Windows XP?

In case you havent, make sure you uninstall the drivers which you have currently installed before installing above one.

Audio dip with external speakers

Has anyone noticed the Macbook Pros will control their analog audio output only when the computer has software requiring audio?
Here is my example:
My Macbook Pro (mid-2010) has an audio cable from the headphones into a splitter. The splitter is also connected to a universal dock (charging station and speakers for my iPhone) before running to a pair of Harman/Kardon Soundsticks II. When nothing is playing on the laptop (or it is not connected) the sound from my iPhone is loud and clear. The same happens when the laptop is connected, but no software is outputting audio. This has always worked fine with my aluminum C2D MBP.
But, with the unibody, if my iPhone is playing music, and I open software requiring audio, such as Quicktime, the audio from the phone suddenly dips to near inaudible levels to clear way for the Macbook Pro. What I believe is happening is that the MBP turns off the output, leaving the lines clear for the phone. But when software activates the headphone port, it charges the line with its own signal and conflicts with the phone. The reason it wasn't a problem with the aluminum MBP is because the audio line was always charged with both signals, so I could balance both outputs and the speakers to sound good. With this new setup, I can't ever balance or gauge levels.
Has anyone else observed evidence of analog audio being controlled by the computer?

I'm not able to understand from your description what your setup is, or why you've arranged it that way. Please clarify.

No Audio Playback through External Speakers

Audio Meters indicate audio is playing. Mute is not engaged. "Canvas Playback" is checked. Perhaps the problem is in the setup, where it indicates that "Playback Output Audio" is sent through Firewire DV. My speakers run through USB, not Firewire. However, the only way I can access setup is through "Easy Setup" which gives me no option to change audio output to anything other than firewire.

The audio will not go out via USB. It will only go to the internal speakers or the speaker jack or go out via FireWire.

No audio in Windows Vista from my external speakers

when using BootCamp (on the OS side), i can hear my audio through my external speakers, but when i go to the WIndows Vista side, i only get audio through the monitor itself. what can i do to fix it so that it all come through the external speakers?
thanks for any advice

It's hard to know exactly which it is at this point. It could be one of two things. The speakers have failed or the jack detect pin located inside the headphone jack has failed. A non-functional jack detection pin would cause the system to route audio to the headphone jack constantly instead of the internal speakers.
If you want to be absolutely certain it is not a software issue (corrupted registry possibly), you can try the system recovery making sure to backup your files. I suspect this is a hardware issue, but it could very well be a corrupted registry causing the jack detection pin not to be read properly.

How do I connect Apple TV to external speakers and my TV?

I just bought an Apple TV for my studio apartment and have it connected to my TV via HDMI, and use AirPlay to stream my music and videos. Video works great, but the my TV's internal speakers are low quality. So, I would like to have my audio come from external speakers (which I have not bought yet), for the following 2 scenarios:
Listening to music via AirPlay, preferably without having to turn my TV on.
Watching videos on my TV, with the audio coming through my external speakers rather than the TV speakers
I see my Apple TV has an Optical Audio (Toslink) port, but the salesperson at the nearby electronics store said none of their speakers have Toslink cables, only 3.5 mm (or USB). The only solution I found is an AV receiver box that has optical input but costs hundreds of dollars. I am looking for something cheaper and am willing to settle for "pretty good" sound quality.
Is there another way to get this to work?
This article recommends using a digital audio converter (DAC) to connect the Apple TV to a stereo amplifier. This seems like it would satisfy scenarios (1) and (2) above.
Also, I found this "Toslink to 3.5 mm adapter" for a few bucks; could I just plug that into my Apple TV and then connect it to any speakers (like computer speakers) with 3.5mm input?
Any ideas would be appreciated.

Rex,
Since the toslink is optical, the 3.5mm adapter will not work for you as it is only ment as a conversion to a mini-toslink cable. Your first option of using the DAC, is in my opinion the best and perhaps only way to get audio out without going to a fancy amp or tuner first.
One option that I'm considering is the Bose Solo TV sound system. It might set you back about 4-Grant's, but I generally enjoy the sound of bose for most music/tv/movie purposes; and it has a direct optical audio input that you can run either from your tv or your ATV. Whatever audio you're sending to your TV via the HDMI, should go to these speakers through your HDTV's toslink output with equal digital clarity.
I've read a few other posts on the apple discussion forum which lead me to believe that the optical output of the ATV might not work so well after the 5.2 update... so whatever I do, it won't be JUST for use with the ATV.

Use external speakers ASWELL AS built in

Is there a way for me to play sound on my laptop with the built in audio aswell as external speakers??
I need an answer today.... THANKS!!!!!

I think a lot of folsk would like to be able to do that - but sadly I think this is a case where Apple's elegant design does not leave the user enough options. It is great that the system can detect when an external audio device is conected - but the user should still have the option of deciding what to do when that is the case --- feedback to Apple is a good idea --- you might try searching over at Mac OS X hints web site. maybe there is some prefs file that can be edited using tetminal

Audio output will not work on external speakers. Internal speakers will work. What do i do to replace audio output slot

audio output will not work on external speakers. Internal speakers will work. What do i do to replace audio output slot

Right click your volume icon in the notification area and select "volume control options". From there, you should be able to select the external speakers.
I hope that helps!
Best of luck,

When external speakers are plugged in to headphone jack, sound randomly goes back to internal speakers or digital audio setting, then back again

I have an essentially new MacBook Pro with Lion and all updates applied, and am wondering if this is a hardware or software problem. Essentially with something plugged into the headphone jack, things work as they are supposed to for a while, then the sound will switch back to internal speakers, or sometimes 'digital out' (I can watch it change in the system settings), and then often switch back. It doesn't seem to follow any sort of pattern or be related to any specific application that could be open, and happens with different sources of audio (iTunes, streaming from the web), and different external speakers or headphones plugged in.

Sounds hardware related. If it's brand new, and you're still under warranty I would have it checked out.
I have not experienced this on my computer.
As I understand it, you have analog RCA outputs from an 1/8" to left and right RCA outputs. when you're randomly using the computer, it'll switch to internal speakers, then to digital audio, back to your stereo analog external speakers.
This should not be happening and if it's happening with streaming content (I am unaware of anything that streams in 5.1 digital audio) then this must be something that an apple specialist should look at and consider.
Does this happen with the headphone jack out? when you hold your finger over the headphone jack area does a red beam come out of it *blinking* or just on? This will be a good indicator that your audio hardware is faulty. are you running HDMI out?

Audio not coming out both external speakers on Lenovo Horizon All-in-one

I have just received my Lenovo Horizon 27 inch all-in-one pc and I've noticed a problem with the audio. When I plug in my external speakers I only get audio out of the left channel. I noticed another person with the same problem posted to the forums some time back but the Lenovo tech never got back to him with a solution so I'm really hoping I'll have better luck.
The sound comes out propperly when headphones are plugged in but my speakers only output a single chanel of audio. The speakers work fine on other PCs. As was suggested in the other thread, I compared the headphone jack and the speaker jack and they are identical. Same number of stripes, same length, and I believe the same girth.
Here's the url for the other post I mentioned: http://forums.lenovo.com/t5/IdeaCentre-Desktops-Home-Servers/Horizon-27-sound-issue/m-p/1475392/high...
I also can't seem to find where the number is to call for support so if someone could help me with that I'd be very appreciative.
Thanks,
Charles

Okay, so I called Lenovo support and as always, they were polite but their solution was that it was a software issue and I needed to restore my computer, so not very good advice but often given by every tech support. It's like cutting off your hand because you have a cuiticle.
Anyway, so in all the sitting and waiting I had a thought come back about when I used to manage a computer store that sold Macs. Apple, when they released the Macbook Air, tried to squeeze so much into the tiny case that there were a million problems with the device one of which was that some headphones and speakers worked fine (namely ones made by Apple, go figure) and others wouldn't work at all. It was a design flaw related to have very low tollerances for minor differences in the headphone jacks length et al.
So I used an extension audio cable with my speakers and it works fine now. So the answer is that there is a design flaw in the Lenovo Horizion related to the effort to squeeze so much into the thin device which lowers the devices tollerance for variations in the size and shape of the headphone plug. I hope this helps someone else since the solution is simple and if it had been in a database it would have saved a lot of time for me and the techs. Not complaining, just wanting to put this information out there for others who might be experiencing the same sort of problems.
