Hp Pavilion dv7 won't play audio through HDMI

Hi i recently noticed my Pavilion dv7 entertainment notebook won't play sound through the tv anymore. The picture is on the tv but sound is running through the laptop speakers? I never had a problem with this until now. When i open up the sound options, the ATI HDMI output says it's not connected and so it wont let me select it, but it is connected? Please help?
Kind regards, Sez.

Hi Sez,
Try using Recovery Manager to reinstall your AMD Graphics Driver package as this will also reinstall the AMD HDMI Audio driver- the procedure for using recovery manager to reinstall Software and Drivers is detailed in the relevant document on the link below.
Recovery Manager - Windows 8.
Recovery Manager - Windows 7
Recovery Manager - Windows Vista
After the reinstallation has completed, restart the notebook.

MBP 13 (mid-late 2010) still won't play audio through HDMI

I would like to connect the MBP 13" I bought in 12/2010 to my HP w2408h 24" monitor through HDMI, both audio and video. I bought a Moshi mini-DP to HDMI adaptor, and hooked everything up like I was supposed to.
When I go to System Preferences > Sound to try to select HDMI as the audio out, it tells me that "The selected device has no output controls." Mind you, I've tried three different HDMI cables, including the Vizio cable I just bought (with gold-plated connectors, natch!). Furthermore, when I try to run audio from the MBP's headphone jack to the monitor's audio in port, there's nothing there!
FWIW I'm running 10.6.6, and didn't try this set up before I upgraded from 10.6.5
What to do? Please advise.

Mind the bump, but I'm having this exact same problem and nothing I try is helping.
I have a mid-2010 MBP, so I know it supports audio. The video works just fine, but when I open up the sound and change the output setting to my tv, it also says, "The selected device has no output controls." But I KNOW that the cable and my laptop work with the audio, because I can play the sound effects under the sound preferences through my tv speakers, but nothing else. Which is REALLY confusing. There's some static coming from my tv speakers, but that's it.
If it matters I'm running 10.8.2.
Help please, and thanks in advance!
Edit... So apparently iTunes works just fine as well. WHY can't I play anything from Chrome? Ugh.

Okay so my IPod touch 4 won't play music through any headphone I put into the port. I've tried it with 4-5 different headphones but it still won't work. How can I fix this?

Okay so my IPod touch 4 won't play music through any headphone I put into the port. I've tried it with 4-5 different headphones but it still won't work. How can I fix this? This isn't the first time something like this has happened but it has never stayed this way for such a long time. If I have to send it in for repairs I will but I'm not sure if its under warranty

To check for warranty coverage:
https://selfsolve.apple.com/agreementWarrantyDynamic.do
- Try cleaning out/blowing out the headphone jack. Try inserting/removing the plug a dozen times or so. There is a little switch in the headphone jack that disconnects the speaker when the headphone jack is inserted.
Try the following to rule out a software problem
- Reset the iOS device. 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 iOS device.
- Make an appointment at the Genius Bar of an Apple store. Seems you have a bad headphone jack.
Apple Retail Store - Genius Bar
If not under warranty Apple will exchange your iPod for a refurbished one for $199 for 64 GB 4G and $99 for theother 4Gs. 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.

Flash won't play audio. Please help!

To anyone who can help,
Flash won't play audio in Firefox, Chrome, Safari etc. Downloaded audio plays just fine but I can't stream any flash audio content. Does anybody have any solutions? Any help would be appreciated.

I'm experiencing the same problem on Snow Leopard 10.6.8. If I go to YouTube, I don't get audio. Other websites are fine (I'm not seeing a pattern on exactly which sites). What I had to do was uninstall Adobe Flash (I used the Adobe Uninstall utility). Now I have audio on YouTube, but now I'm getting a lot of 'missing plugin' messages from other websites. I've opened

My internet won't play videos through safari or YouTube... What if I do

My internet won't play videos through safari or YouTube... What if I do

Wifi? Cellular? That's not much to go on. More details help. If you think it's your internet contact your provider or carrier.

IOS 6.0.1 Safari won't play audio files. Error: "Cannot play audio file."

I recently updated my iPad to iOS 6.0.1, now Safari won't play audio files in any format. Error: "Cannot play audio file." Previously, it worked fine. I tried downloading and using GoogleChrome and Opera Mini, and these also won't play audio. What's up??

Solved the problem. It seems that once iOS 6.0.1 installed, it caused all of my browsers to mishandle audio files. When I reset the iPad, that cleared up the problem.
Before upgrading to iOS 6, my browsers would "autoplay" the sound files. After iOS 6, "autoplay" is disabled so you have to manually click play to play them.
Nonetheless, everything is working fine again except for "autoplay," which I can live with.

Some apps won't play sound through iPad2 speakers

I've noticed since updating to iOS 5 and 5.0.1, I've got more apps that won't play sound through ipad2 speakers, but will play sound through earphones though. Using the same app on the iphone plays sound through the iphone speakers as normal.
It seems to be picky with which apps it does this to as Sky News/BBCiplayer/YouTube/Video/ IMDb all play sound through ipad speakers. Apps like FilmOn plus/ FreeAppMagic/ Falling Gems/ Bejeweled2/ FNS Shift2 will only play sound through earphones. These Apps updating to the new iOS doesn't fix the sound issue either.
I can use an app that plays sound through iPad speakers, then use an app that doesn't play sound through the speakers, then use another app that does play sound through speakers, so the earphone connection actuator doesn't look like the problem to me. Maybe some sound drivers may have been lost or deleted with new iOS updates over wifi...?
Any help would be appreciated.

See if perhaps this is the reason why some apps aren't playing sound.
If you lose sounds for keyboard clicks, games or other apps, email notifications and other notifications, system sounds may have been muted.
System sounds can be muted and controlled two different ways. The screen lock rotation can be controlled in the same manner as well.
Settings>General>Use Side Switch to: Mute System sounds. If this option is selected, the switch on the side of the iPad above the volume rocker will mute system sounds.
If you choose Lock Screen Rotation, then the switch locks the screen. If the screen is locked, you will see a lock icon in the upper right corner next to the battery indicator gauge.
If you have the side switch set to lock screen rotation then the system sound control is in the task bar. Double tap the home button and in the task bar at the bottom, swipe all the way to the right. The speaker icon is all the way to the left. Tap on it and system sounds will return.
If you have the side switch set to mute system sounds, then the screen lock rotation can be accessed via the task bar in the same manner as described above.
This support article from Apple explains how the side switch works.

No audio through HDMI cable when listening to audio tracks but ok with vids

Please Help!!
Ok I hooked up my HP to my Samsung 1080p hdtv through an HDMI cable. My computer displays fine on the TV, the visualizer in ITunes shows just fine, but the audio only comes out of the speakers on my laptop when playing a regular music track. When it plays one of the bonus music videos on the same album, audio and video both play. When I play the songs in any other interface, ie windows media player and HP quick play, audio tracks play fine through HDMI. So this has to be something with ITunes. Anyone know what the problem is?
Thanks!

Wouldn't you know it, just figured it out. You have to make sure that itunes is not loaded before hooking up the HDMI cable. So,
turn off itunes,
hook up the HDMI cable,
(go to sound [control panel] and make sure that HDMI has the checkmark next to it),
load itunes,
enjoy.

IPOD Classic - Can I play music through HDMI

I have a TV with HDMI in
Bought a non Apple cable to play music through HDMI input
Can I PLay music through any HDMI convertor cable
Thanks

The iPod classic supports composite or component video. Unless you have something with enough smarts in the cable to convert that to HDMI then it isn't going to happen. There are no apps for the iPod classic and it doesn't have the hardware. Does the TV have component, composite, S-Video or SCART inputs? Any of these could be driven from the classic.

Windows 7 on my iMac won't play sounds through headphones

On Windows 7, I can't make sounds play through my headphones plugged into the audio jack; the internal speakers always do it instead. The headphones don't appear in the "Playback devices" column, even though RealTek recognises that something's been plugged in/unplugged to it.
Also, the latest version of Boot Camp software drivers I burned to a DVD after upgrading to Lion (v.4.0) refuses to start; it keeps saying that 'Boot Camp x64 is unsupported on this computer model"; I was able to install the v.3.0 drivers by using "Troubleshoot compatability" within the Drivers/Apple/BootCampx64 before, but now it insists I use setup.exe- which refuses to install, even in compatability mode!
It's incredibly aggravating, since I always use my good headphones for gaming so I don't disturb my wife! Help!

So the Bootcamp 4.0 drivers won't work with my 2008 iMac? I'm running 3.3 then, and the problem persists.
I've just tried uninstalling the RealTek drivers; Windows seems to auto-install a "High Definition Audio Device" that DOES play sounds through the headphones... albeit incredibly quietly. Barely perceptible at full volume. I've tried to install the Cirrus drivers from the 4.0 Bootcamp disk; they claim to install correctly (in less than a second, which makes me skeptical), but they still don't appear.
It seems I can have Realtek and no headphones, or no Realtek and minimal sound...

Windows 7 on dial-up won't play audio files

My brand new Compaq Presario CQ5320F running Windows 7 (64 bit) connecting to the internet with dial-up will not play many archived audio shows I like to listen to. Different sites have different set ups. The only sites that play properly have a STREAM button. Other sites just have a link to click. Some of these will only play after the whole show has 'downloaded' which does not work for me (I need to listen to the beginning of the show to know if I even want to hear it). Others sites with a link to click never seem to get connected as 'connecting' keeps displaying and nothing ever happens (even if I wait forever). This is all using Windows Media Player that came with the computer. On my old computer running ME I often went to the properties tab of an audio link and then pasted this in the media player. I decided to try this with my new computer but I can not find a place to put a URL address in this new version of WMP. Plus I am unable to fast forward a show with this new version (which I currently am inclined to think s....ks). Since I am using dial-up would I be better off removing this new version and replacing it with an old one, or is there some way to get it to work?

ITunes won't play audio with mp4 or mov video

I have wasted many frustrating hours now trying to get iTunes to play mp4 and mov videos but can't get any sound. A few months back it was working fine. Tried ALL the suggested fixes like uninstalling, updating and checking all the MIME/File boxes. When I went back to QT 7.5 and played the files independently of iTunes everything was fine. Quicktime 7.6, 7.67 & 7.7.1 do not play the audio independently or under iTunes and of course iTunes won't play video with QT less than 7.7.1. The same mp4 videos uploaded to my iPOD work fine. I currently have iTunes 10.5.3.3 installed on a Windows XP SP3 on an e-machines pc. Ideas please!!

I got this problem as well. Seems as soon as I moved to version 7.6 it stopped playing my video audio. My music plays fine, but my video audio is non-existant. It's not the file itself because I can play off my iPod (though not off my iPod through iTunes) just fine. I've done all the suggestions above and NOTHING has worked. Is there anything else we can find???

FCO 10.2 won't play audio. Was fine in 10.1.4, projects open fine, the meter shows it playing, made all correct connections in Inspector, but no sound to system?

Since upgrading to FCP 10.2 from 10.1.4, I'm now not able to get sound even though it shows it's playing in the meter. The clip is a .wav 48k, I have highlighted the audio, gone into the Inspector, chosen Audio, in Pan Mode I've chosen Stereo Left/Right and made sure Stereo is selected on the file in the Channel Configuration. Solo does not help nor is skimming available.
All other audio apps are fine including Quicktime.
Also, I triedstarting a new Project and Importing audio, but the same result. Please let me know what I'm missing.
Is there a way to rollback to 10.1.4 to finish this project?
Thank you in advance for your reply.

Thanks Tom- shortly after I posted I read that and the multichannel change in the AudioMidi Setup was indeed the answer!
In reading through the posts, I see you have had answers to many issues so perhaps you help with this :
In 10.1.4, I had used an FX Factory effect for scrolling credits and now it won't play back on 10.2. If I highlight the clip, I have the ability to edit the text, but it won't play- any help is appreciated.

Thanks again, Tom

Is there a way to play video through HDMI and have the audio via the headphone socket?

I would like to be able to play movies through the HDMI adapter to a projector, but to have the audio via the headphone socket to a separate audio system. What I find is that as soon as I connect the projector via HDMI, the audio via the headphone sockeet is cut off. Any ideas?

Yes, there is a very simple way to get audio out through the iPad headphone jack even while connected to HDMI to play movies on a projector or TV. In fact, I just did it last night for a presentation.
With the HDMI adapter connected to the projector and your audio jack plugged into your iPad headphone jack, go ahead and start the movie. Then simply unplug the headphone jack and plug it back in. The audio is now routed through the headphone jack again.
I found I only had to do this once per session. That is, Iwas able to stop the movie, go to the beginning of my presentation, wait the 20 minutes for the meeting to begin, and when I got to the video clip the audio still played out through the headphone jack to the PA system.
I had built a presentation in a Web oriented training tool and it was running on Safari iOS7 with the latest update. I have not tried it with Keynote yet.
