Playing video AND audio through TV speakers using Mini Display to HDMI adapter

I have a late 2011 MBP and want to hear the sound of the videos I'm running on my MBP through the speakers of my LG HDTV. I have used a Belkin Mini DisplayPort to HDMI adapter (model f2cd021eb) plugged in to my MBP with an HDMI cable running from it to my LG HDTV. The video shows on the tv, and sound plays thru the MBP speakers. I have used an off-brand Mini DispalyPort to HDMI cable (without any adapter) - that is, it plugs directly into my Mini DisplayPort on my MBP and the HDMI port on my LG TV. The video shows on the tv, and sound plays thru the MBP speakers.
System Preference > Sound > Output, selected LG TV (type HDMI) and the note that displays is "Settings for the selected device: The selected device has no output controls".
I open Audio Midi Setup. It lists Built-in Mic (2 in/0 out), Built-in Input (2 in/0 out), Built-in Output (o in/2 out), HDMI (0 in/2 out). The Built-in Output is selected by default. The source is Headphones (Format 44100 Hz, 2ch-24bit integer, ch master far left, ch 1 and 2 far right with value of 1 for both dB of 0 for both).
Upon selecting HDMI, the source changes to LG TV (Format 48000 Hz, 2ch-24bit Interger, ch Master, 1, and 2 to far left and unavailable to adjust).
Upon selecting Configure Speakers, I click left front and right front and hear sound coming from the tv speakers just fine...loud and clear.
I'm deployed overseas and getting products through the mail is really really slow!! So any insight you can offer would be great!!

I was wanting to do the same and was at the verge of following The Official Way (Apple dongle + HDMI male to male cable). But on the trip to the store, found a TechLink iWire TB male to HDMI male adapter cable for half the cost, bit the bullet and got it instead: http://www.techlink.uk.com/products/apple/iwires/iwires_mini_displayport_plug_to _hdmi_plug
First time use with a Hitachi TV was disconcerting. Used to the old VGA setup, plugged everything in (while the rest of the family was watching regular TV on the unit), fully expecting the Mac to recognize the external display and send the signal over. No go. Tried resetting the PRAM, rebooting the Mac, no joy. Was about ready to write the cable off as a bad POS, when in a flash of inspiration switched the TV's input over to its HDMI port. Lo and behold, the Mac switched res and started sending sight and sound over at the TV's native capabilities. Did not need to fiddle with any adjustments at all. Sound was great, display crystalline clear. Wowed the folks.
And if I switched the TV to another input, the Mac would immediately disconnect and revert to its usual settings.
So yeah, the cable can be a culprit, but so can whatever's on the other end of the cable

Mac is not connecting to TV after using Mini DisplayPort to HDMI Adapter Cable?

Macbook Pro is not connecting to TV after using Mini DisplayPort to HDMI Adapter Cable. 2010 Macbook Pro, just purchased Mini DisplayPort to HDMI Adapter Cable from Amazon. Link here: http://www.amazon.com/Mini_Dis-HDMI-CB6-Mini-DisplayPort-Adapter-Cable/dp/B003OC 6LWM/ref=sr_1_2?ie=UTF8&qid=1406238976&sr=8-2&keywords=mac+to+tv --When i connect both ends of the cable to the TV and to the laptop, the screen will blink, but then afterwards it will not mirror on the TV. I have tried going to display setting but cannot find the arrangements tab. When i searched "arrangements" a message said, "The Arrangement tab of Displays preferences is hidden because you only have a single display attached to this computer." Not sure how to fix this problem. I have connected this laptop to a TV before, but with a different cable other than the one i just purchased. Any help would be greatly appreciated, thanks.

Found the fix. Still don't know if it was Windows, iTunes, or Norton 360, but this worked immediately for me:

I found a solution posted from Rodfromnework for PC users. It worked for me and easy to do.
Start --> Programs --> Accessories (Right Click on Command Prompt) --> Run as Administrator
then type in:
Netsh winsock reset
Hit enter, restart PC, open iTunes, go to Store
Hope it works for you too.

Composite AV Cable will play video and audio, but not music

I just bought an Apple Composite AV Cable to use with my iPod touch 3rd gen. It will play videos and the accompanying audio through the TV with no problems, but it will not play just music. What's the deal?

No. However, you can get a cable from the headphone jack to an audio input for your TV.
The Apple universal dock also has audio out.

Firefox doesn't play video and audio, cann't download anything!

A very strange problem occurred a few days ago. I didn't pay attention on it at first ( I thought it was caused by my provider) but now I found that it's a real problem. Firefox doesn't play video or audio. For instance, it starts loading and that's all. The same is with playing music. In addition, I can't download any files and view a big image as quick as early.
What is more interesting sometimes Firefox just begins to work in ordinary way.

There is no single codec for movies that have .avi extensions. AVI is a container format, not a specific type of file. An AVI movie may use one of the Indeo codecs (there are at least four that I'm aware of, none of which have been ported to Mac OS X) or one of the various flavors of DivX, among other possibilities. You'll have to find out what codec was used for the movies you want to view to determine what you need. Note that not all codecs for the various .avi movies are available for QuickTime.
If you want to try "hit and miss", you can try the codecs at http://www.divx.com/ and http://www.3ivx.com/ and see if one of them will work for you. Perian, which rolls several codecs into one package, might also work.
If you just want to play the movie any way you can, you can also give this player a try:

Can't play Video and audio tracks.

I'm using Windows 2000.

Most of the iDevelop 2001 videos and audios require a Real

Hooking Up LCD TV Using mini DP to HDMI adapter ?

I am wondeirng if the Mini DP to HDMI adapters will work for my application as I have searched a few MFG. websites for the details but it seem all will only work fully (audio + video) with a LCD TV with a HDMI chip V1.3 or above. A LCD TV with a HDMI chip below V1.3 will get you only video.
My macbook pro supports audio though the Mini DP I know this for sure.
I cannot find the version of HDMI on my TV it is a Toshiba 42hl196 made in 2006. But I am betting it is older than V1.3.
I was trying to get away with only one cable so the Mini DP to HDMI adapter is the way I am wanting to go.
Can anyone tell me what version HDMI chip is in my Toshiba 42hl196?
Also can anyone recommend a Mini DP to HDMI adapter that would work for my application? Or am I stuck buying two cables like a Mini DP to VGA - connect to TV then run component audio (W/ stereo adapter) out of headset output on Macbook to TV?
This is what is listed under HDMI in my TV's manual:
Suggested formats; 1080i, 480p, 480i, 720p
HDMI Audi; 2 channel L-PCM 32/44.1/48 Khz sampeling freaq. 16/20/24 bits per sample and Dolby Digital

http://store.apple.com/us/product/H1824ZM/A/Moshi_Mini_DisplayPort_to_HDMI_Adapt er
if your tv says hdmi audio it has hdmi audio (which it does) get this anyway since you're trying to make this connection and make sure you set your sound to the hdmi audio.

Is HDCP protection always on when using Mini DisplayPort to HDMI adapter?

I'm trying to capture my MacBook Air (2010) desktop for use in a Podcast.
So I purchased a Mini DisplayPort to HDMI adapter and plugged that into a HDMI capture card on another machine.
Unfortunately it keeps telling me the stream is protected and it won't display anything.
I've tried my 2010 iMac and 2011 Mac Mini too, but they all produce the same issue.
If i plug them directly into a TV instead then they display fine, but not when connected to the capture card.
A windows based laptop with HDMI out works fine as does a DVD player. But when I attempt to play a cop protected DVD - then the HDCP kicks in and the picture is blocked.
Does anyone know if there is a way to display just the Lion Desktop without invoking HDCP protection?
Thanks in Advance
Anthony

Is the failure repeatable? If not, I would forget that it happened once and move on. It had something to do with pages moving in and out of the registers. S**t happens.

When using mini port with HDMI adapter, can only see front page (stars) will not display whats on screen??

Using a HDMI adapter on mini port the only picture on TV is the front Mac page (stars) and not whats on the Mac screen.

Thanks for taking the time to respond, after I posted my brain kicked in and I recalled that mid 09 were not audio compatible. not a big deal anyway since there are multiple ways to listen...
again thanks,

How do I use a mini display to hdmi adapter to view my laptop on my tv?

I bought a mini to hdmi adapter and I have an hdmi cable plugged into the TV but I get no picture and there is no other diplay detected by the computer.

Is your TV set to HDMI input? Also, many TVs have more than one HDMI input and you must tell the TV to use the one you are plugged into.

Playing video and audio on PDA (ie: PALM)

just wanted to know if I can play audio, video & podcasts on my PALM PDA?
Sanjay
Windows XP Pro

If talking about purchased items:
regarding TV shows - you can't as their DRM prohibits conversion to any other format.
regarding audio tracks - you have to burn them to an AudioCD and have to re-iport the resulting CD to a file format that your PDA is able to handle.

Video and audio files from dvd using FCP

Hi
Trying to get footage from a dvd using fcp. I can import the clips ok using file >import but they have no audio with them and the audio folder on the dvd is blank...any ideas????????
cheers

The audio_TS folder is normally blank.
You need to use MPEG Streamclip to get the DVD files to Quicktime.

Is there a way to disable the auto play video and audio ads that are showing up on the web these days?

A lot of sites have video ads that load and start playing while safari is loading the entire page - slows everythiing down. Also a couple news sites I go to have autoload/play content. Is there a way to disable these auto loads?

Install the ClickToFlash or ClickToPlugin Safari extension.

Making QtWebkit support HTML5 video and audio

For those who don't know, HTML5 enables most current browsers to play videos and audios without the need of any plugin. QtWebkit supports this feature, so browsers using it such as Rekonq and Arora should support it too. However on Arch Linux this does not work outside of the box.
I've tried to make this work and made a little progress, and I'm wondering if anyone has made similar attempts, have suggestions, or are willing to try this out. What I've done basically is to compile Qt with Phonon, and then remove the Phonon files when building the package, so that it uses the Phonon that comes with KDE. I included the PKGBUILD below, and you just need to copy the extra/qt directory from abs, and override the PKGBUILD or apply the patch.
I also installed phonon-vlc-qt from AUR, which according to this post contains some fixes to support HTML5 video/audio. However neither this nor the default gstreamer backend works for me. With vlc the vidoe doesn't play, and with gstreamer the browser crashes. To try different backends for Phonon, open KDE's System Settings - Multimedia - Backends, and use the Prefer and Defer buttons.
Some links for testing HTML5 video and audio:
http://html5test.com Only uses JavaScript to ask the browser if it supports the feature. What I've done does make these tests pass.
http://html5video.org
http://youtube.com/html5 Join the beta, and then open some youtube videos, and look for HTML5 in the player's control bar

Use a minidisplay/HDMI cable for video:
http://www.cnaweb.com/6-mini-displayport-male-to-hdmi-male-cable.aspx?gclid=CMbn pNem57wCFRQS7AodzDQACg
A 2009 MBP does not support audio via HDMI so you will have to tap the Audio Output port. Use a 3.5 mmRCA plugs and tap the RCA audio inputs on the TV with a cable such as this:

Yosemite airplay video and audio stutter

After upgrading to the official Yosemite /not the beta version/ on my iMac 2013 and MBP the airplay streaming of video and audio through any of my two Apple TVs results in intermittent audio and video stuttering which can drive one crazy. Sound and picture are choppy no matter from which computer or to which apple tv streaming is implemented. Any advice how to fix this issue - airplay has become practically unusable to me and family....

You can see here that many people report for this problem.Unfortunately, OS X Yosemite has a minor bug and can stream correct video and audio to Apple TV via AirPlay. You can not do nothing expect to wait for next OS X update. I have same problem and can use my apple TV.
I don't know why Apple doesn't fix this before official OS X Yosemite release, because this problem was report in there beta program from many users.
