HT2494 No Audio with Thunderbolt

I'm hooking my 2012 MacBook Pro 17" running Lion to my HDTV via the thunderbolt to the HDMI port on my TV. From what I understand, Thunderbolt is suppose to output ideo and audio, but I'm getting no audio. Does anyone have the fix for this issue. Thanks

Have you checked system preferences/sound, output tab to see if you can select that output?

How do I use my late 2011 iMac ( with thunderbolt) as external monitor for laptop/Xbox or other device with hdmi as output.

May be this question has been asked thousand times. how do I use my mid 2011 iMac ( with thunderbolt) as external monitor for laptop/Xbox or other device with hdmi as output. if apple hasn't removed that feature and has just moved that functinoality to thunderbolt then how can I use it. currently there is no laptop available with thunderbolt output. no 3rd party converter available. whats the use of having feature on latest functionality if we cant use it. I wish they would have made one port has mini-dvi and other thunderbolt for backward compatibility untill some vendor comes up with converter.

It Says :
Mac (21.5-inch, Mid 2011) and iMac (27-inch, Mid 2011) and later computers support Target Display Mode via Thunderbolt to Thunderbolt cable (2 m) when the source is another Thunderbolt-equipped computer.
Name one computer model/vendor which has thunderbolt as output for display + audio. this is so stupid to move to new technology without availbility of its compatible devices.

Anyone else having trouble connecting MBP with thunderbolt port (TBp) and 27"iMac with mini display port (MDp)

I have a 27" Imac.i7 with mini displayport and MBP13 i5 with thunderbolt port. Some time ago I tried to connect my old MBP with miniDP to The 27"iMac I Failed so did the apple centre they refunded cable costs and said I'd be contacted by Cupertino. That was 9 months ago, now replaced MBP with 13 inch(**** I can use my iMac as display!). Does not work phoned Fast Lane very helpful guy called JIM emailed me some software/firmware update links. Still no display linking. One of the links was for a couple of updates for a TBp equiped 27" iMac mine is only MDp equiped. Failing to find any MDp updates in apple support. Anyone have any Ideas! My lad has a later 27"i5 he uses Xbox 360 no problem on his but it wont look at my MBP.
Beginning to feel like some of the kit that went with a fully loaded 5500 worked eventually. Computer and FM radio, Photography kit fine, video capture audio capture forget it. Too many crashes and resets made it impractical.

How to connect Air with Thunderbolt?

How do I connect Air with Thunderbolt?
Bought Air in Oct 2011 and Thunderbolt today.
Does Mac OS X (10.6.5) work with Thunderbolt?
Do I need a special cable other than what came in box?

Hey moxiedoggy,
Welcome to Apple Support Communities! It sounds like you want to use Target Display Mode to use your iMac as a second screen to your MacBook Air. Since your said your MacBook Air is from 2011, it should have the thunderbolt, and you can connect the two computers using the following instructions:
Use an iMac with Thunderbolt as a display
If you have an iMac with Thunderbolt, any other Mac with Thunderbolt can use it as a display. The iMac will play both the video and audio from the other Mac.
Connect the Thunderbolt cable to the Thunderbolt ports on each computer.
Make sure both Mac computers are turned on and awake.
Press Command (⌘)-F2 on the keyboard of the external display Mac.
If you want the external display Mac to play audio as well as video from the primary Mac, choose Apple menu > System Preferences, click Sound, and then click Output. Select the external display Mac from the list of devices.
You'll want to go over the requirements for using Target Display Mode here, along with other FAQs:

Pegasus RAID Storage with Thunderbolt opinions / backup solutions?

I'm trying to get some opinions about the Pegasus RAID Storage with Thunderbolt
http://www.promise.com/storage/raid_series.aspx?m=192&region=en-global&rsn1=40&r sn3=47
since I've been researching some info for a friend who is looking for extremely reilable local storage solution for his record label.
Does anyone here use this? If so, do you use it with Time Machine? And also what type of RAID setup did you use?
I was thinking of a RAID 5 setup, since I feel that would be best in the long run should any drives fail, the backed up data would still be available on the other drives even if the performane is a bit slower until the failed drive is replaced. I would like to hear about people's experience with these drives and RAID setups. Also if anyone might want to suggest other disk options, please feel free to mention them here.
This would mostly be for "Setup 1" which is mostly audio production dedicated.
There is also a need for a "Setup 2" which would be mostly business/document dedicated.
Would it be better to get another smaller local back up solution for Setup 2?
We're not too keen on using Time Capsule for Setup 2 as their long term performance does have a great track record.
We're also going to be using Carbonite to have an offsite/remote backup of everything we have locally, but I'm not too familar with their services as well and if anyone here can comment on that I would apprecaite it. I've read up a bit on them and I would think to probably use their Business level service.
Any help, advice, opinions are welcome and appreacaited!
Thanks!

You can (re-)install to the Pegasus raid and boot from it.
However, you'll actually get a faster system if you use an SSD for the system drive and then just use the Pegasus for data files (and Time Machine backups of the SSD ...).
In any case:
Be sure to use the Promise Utility (download it from their site) to configure the RAID level etc if you don't want the default RAID 5 configuration. (For me I prefer RAID 6 if there are more than 4 drives, RAID 1 for 2 drives and RAID 10 for 4 drives – RAID 5 is just too risky; even configured with a spare).
If you use the Pegasus as your system drive, consider using RAID 10 on it. You'll "only" get 6 TB storage; but it'll be fast and quite safe (much safer than RAID 5).

Final Cut Express won't capture audio with the video anymore, why?

I have used Final Cut Express 4 for over a year now with no problems, but recently I am unable to capture any audio with the video from my camera. I can do it through iMovie no problem. I can't figure out if I changed a setting by accident because everything looks normal to me. Could another program be interfering with this? Quicktime Pro? I have no idea how to fix this.

First of all, we need a bunch of information in order to help. Please provide the specs of the footage and the sequence you are using. Also, are you using DV, HDV, or AVCHD? Do you hear audio when the clip is played in the viewer, or is there no audio at all once the clip is captured/ingested?

Unable to record internal audio with RecordMyDesktop

In order to record sound and video from my desktop, I installed RecordMyDesktop (https://wiki.archlinux.org/index.php/RecordMyDesktop) and followed the instructions from post #4 and #6 on a thread about "Recording internal audio with alsa and recordmydesktop" (https://bbs.archlinux.org/viewtopic.php … 3#p1359593). When I try to record with "recordmydesktop --device looprec", it will not start recording and closes with the following error:
Initial recording window is set to:
X:0 Y:0 Width:1920 Height:1080
Adjusted recording window is set to:

If this information would be helpful, I use alsamixer and "aplay -l" gives the following:

I can record from the microphone with with the command "recordmydesktop". I succeeded in recording the internal audio with audacity by choosing the device "looprec" for recordings. I'm not sure why RecordMyDesktop gives an error while Audacity does not. Below is my ~/.asoundrc, which I copied from the aforementioned thread. I am not knowledgeable, but I guess there is a mistake in it? Would you please assist me solving this error? Thank you for your time.

Connecting Cinema Display with mini display port to macbook pro with thunderbolt port

I am trying to connect a 27" cinema display (2010) that has a mini display port cable out of the back, into my macbook pro (2013) with thunderbolt ports. The mini display port cord fits into the thunderbolt port on the Macbook Pro, however the macbook pro does not detect the cinema display and the cinema display does not have any picture on the screen. The USB plugs in fine and sound comes out, and I have the adapter for the magsafe to magsafe 2 and that works fine, it just the actual display. Any help would be appreciated!
Thanks!

Hello mmholt,
Welcome to Apple Support Communities.
It sounds like there’s no video on an Apple Cinema Display that’s connected to your MacBook Pro, and you’re wondering if the configuration is supported. It is supported, take a look at the article linked below for more information.
Thunderbolt ports and displays: Frequently asked questions (FAQ) - Apple Support
1. Can I connect a Mini DisplayPort monitor or monitor using a Mini DisplayPort adapter to a Thunderbolt port on my Thunderbolt-equipped Mac?
Yes. A Mini DisplayPort display or a display connecting with a Mini DisplayPort to VGA, DVI, or HDMI adapter will work just like it was connecting to a Mini DisplayPort connector when plugging in directly to the Thunderbolt connector on your Apple computer. Click here for more information on Mini DisplayPort connections and adapters.
Also, this article provides a lot of great information and troubleshooting tips that will resolve most issues related to video external displays.

Mini-Display Port == ThunderBolt.
In other words, just plug it in.

You should also ask this in the MacBook Pro forum. This is the forum for the 13” white and black plastic MacBooks that were discontinued in 2010. You should also post this question there to increase your chances of getting an answer.

I would like to extend the screen from my circa 2013 27in iMAC with thunderbolt onto my circa late 2006 imac using the DVI port on that iMAC. Is this possible? If not is there another approach I can use?

I would like to extend the screen from my circa 2013 27in iMAC with thunderbolt onto my circa late 2006 imac using the DVI port on that iMAC. Is this possible? If not is there another approach I can use? My 2006 iMAC is showing it's age but I figure I can use it as just a monitor just fine. Assuming I can connect the two together.

That older iMac isn't designed to receive video input through the mini-DVI connection. Only certain newer iMacs are able to be used as displays.
Your only options are to use something like ScreenRecycler mentioned above.

Can 2012 iMac be used as monitor for PC with thunderbolt?

Hi,
Im planning on buying a new 2012 iMac and was wondering about TDM - Target Display Mode.
My PC rig is up for a new motherboard and the thought was to buy a thunderbolt equipped one and then use my shiny new iMac as display for it.
That way I can switch between them easily and only use the one screen. I know Apple support pages tell you that any thunderbolt equipped mac can use the iMac in TDM but what about a Windows PC with thunderbolt motherboard?
Any help is appreciated!

You might try using the Parallels software program that enables Windoze to be run on a Mac; that way you could eliminate a second keyboard too. But then, if you had Parallels runing on your Mac the PC would be totally and utterly superflous since you could just load all of your PC stuff into a sub-directory on the Mac HD. It'd run better too.
That is fine If he has a Non Branded install of Windows on his PC. In other words a Retail copy of Windows installed on his PC. None of the Virtual Machine programs let you import a Branded installl of Windows. That is Totally against the license terms. When I say Branded I mean a version that came with the PC from makers like Dell, HP, Sony and the like. Those versions are for those specific brand of PCs and can Not be moved or installed on other hardware, virtual or physical.
And to your comment that it will run better on a Mac is just completely false. No OS runs better in a Virtual Machine then it does on it own set of physical hardware. Not only that but if you use Boot Camp to install Windows on it own partition on the Mac the Mac still has limiting factor invovled that are not present when running on Real Windows PC hardware.

Is the display turned on? Sometimes it is the simplest of solutions, when details are missing.

No audio with video, website navigation impaired, I can no longer recommend Firefox

I maintain the video site shaleshockmedia.org. I can no longer recommend Firefox to viewers because of the severe problem I have been experiencing: No audio with video; navigation often does not work. Maybe this is purely a local problem. Please let me know if the site is fully functional or not when you go there. There is no problem with Chrome or Safari. My computer is a Macbook Pro 3,1 Intel Core 2 Duo. MacOs 10.6.8

Note that there are a lot of popular extensions that can cause issues with videos not working apart from issues with the Flash plugin.
In what way is the navigation not working properly?
Can you give some examples?
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe mode start window or otherwise make changes.
*https://support.mozilla.org/kb/Safe+Mode
*https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
Check for problems with current Flash plugin versions and try these:
*disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
*disable protected mode in Flash 11.3 and later
*disable hardware acceleration in the Flash plugin
