I worked out I can get visual from HDMI 3 and no picture.
Sound comes though PC1
Did you fix the problems?

For Video/Audio: Macbook Pro (2009-17" 2.66Ghz i7) vs. Macbook Pro (Current 2011-15" 2.4Ghz i7))

So I currently have a MacbookPro 6,1 - I believe a late 2009 model, 17" 2.66Ghz i7 Dual-Core Processor, 8gb Ram (updated), NVIDIA GeForce GT 330M. I started doing video and even noticed this when I normally do my audio work - that my video doesn't look like it should (noticed when a client looked at my computer screen and noticed that colors, brightness was off and extra grainy as compared to other computers he has seen his work on. I also noticed I sometimes get a lag when playing video causing me to have sync issues (off by a couple frames or so -- which completely ***** when I'm trying to do my job right).
So I found a sweet deal on the newer Macbook Pros. Seller told me it retails for around $2400 so I'm assuming it's the Quad-Core 2.4Ghz 15" with some minor upgrades. Let's just say it's this particular model - am I better off selling my older model for this one? I would just hate to part with my 17" although it would help take off some travel weight.
I'm not good with specs which is why I'm here, but apple store says it has:
Intel HD Graphics 3000
AMD Radeon HD 6770M with 1GB GDDR5
And I think that might help solve my problems, on top of the Quad-Core addition which I believe my current macbook6,1 doesn't have right?
Thanks!

Thanks. At this point, portability isn't that important which is why I'm thinking of the upgrade. How do you figure that the iMac is better. The specs on my MBP are still superior with the i7 at 2.5GHz vs the iMacs i5 at 3.5GHz.... hm.. isn't the i7 faster than the i5?
Not in this case. The iMac has a "Haswell' CPU whereas the MBP has a 'Sandy Bridge' CPU, two different generations of processors. To graphically illustrate the performance differences between the two options look at the respective machines in this link:
https://browser.primatelabs.com/mac-benchmarks
Note that the iMac registers a score of 3893 vs the MBP score of 2700. In real world terms, differences of a couple of hundred points often is inconsequential, but here we are dealing with a very significant difference of over a thousand points.
If portability is not a requirement and the bank account is fat, the iMac is by far the better choice. A larger and better display combined with much superior CPU and GPU.
Ciao.

Audio Macbook and Macbook Pro ???

I am torn between the MB and the Pro 15". I want to use these machines to do presentations using tV's most of them will not be HD. Can I hook up (with adapters) to standard RCA connectors with either of them?
Also I am hearing that the MB sound volume is not that great but it offers analog and Digital in and out connectivity which the MBP does not.
Can I connect via rca connectors the laptop (s) and get sound through the tv speakers?
Thanks in advance.

you can have the mini dv to video adapter this could be the one, but please double check before you buy it.

The Apple Mini-DVI to Video Adapter is designed for use with the iMac (Intel Core Duo) and 12-inch PowerBook G4. The adapter connects to the Mini-DVI port on the new 12-inch PowerBook G4 and provides both S-video and Composite video connectors. It allows many devices such as TVs, VCRs, or overhead projectors with S-Video or RCA (Composite) connectors to be connected to your iMac (Intel Core Duo) or 12-inch PowerBook G4.
Use a separate Mini-DVI to VGA Adapter for VGA video out support (included with all new 12-inch PowerBook G4 systems or available for order as a standalone kit).
And you can use the mini jack cable with split red and white rca on the other end to connect the audio out from MAcBook to your TV or stereo set. as it said on MacBook spec:
Built-in stereo speakers, built-in omnidirectional microphone, combined optical digital audio input/audio line in, combined optical digital audio output/headphone out.
Hope this help.

Problema scheda audio macbook pro

Audio & MacBook

I connect a guitar in the built-in input : I've got a signal but I can't hear the guitar in my headphone (built-in output).
I try to play guitar in guitar rig demo. This soft doesn't see the built-in audio input ("not connected" in the audio preferences even when I select CoreAudio, built-in input).
Only Garage Band let me hear the guitar. My G3 beige was more simple for audio things...
Help and sorry for my english.

check www.versiontracker.com for a program called LineIn. I think it should be what you're looking for.

ATV audio (HDMI)

While watching a movie from ATV the unit gets hot. Once hot I losses audio. I have checked the connection. I have also tried listening to music. It just losses all sound. The only solution I have found is to unplug it and let it cool down and restart. Once cooled down it works normally. I know it isn't good for the hard drive but either is getting so hot the it losses sound. Any ideas on how to fix this issue with out buying a chill pad or proping ATV up?
Apple TV Mac OS X (10.4.9) Apple TV getting hot losing audio
Macbook Mac OS X (10.4.9)

I've seen reports of issues between samsung tvs and the tv, don't know whether its certain models or not, a search for samsung in this forum might reveal more.
It's an HDMI issue, when you disconnect and reconnect you will start a new connection and things will work again until the issue reoccurs. When you disconnect to put it in front of the fan and reconnecting when cool, all you are doing is disconnecting and reconnecting, the cooling is not causing anything to start working.
There is the possibility that you could acheive the same disconnect/reconnect outcome by simply turning the tv off and on again, have you tried it.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below on this page to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -f -a TextEdit
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; sudo defaults read com.apple.loginwindow LoginHook 2> /dev/null; } | open -f -a TextEdit
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}' | open -f -a TextEdit
Step 4
ls -1A /e*/{la,mach}* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -f -a TextEdit
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of every login item' | open -f -a TextEdit
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

How to connect my Macbook Pro to HDTV Polaroid with Audio

I connect my cable mini dvi in my macbook pro to my screen Polaroid 40 "I have video but I have not audio, and I went to the System Preferences menu to change the audio output and can not hear anything on the screen
thanks

The yellow RCA jack is called "NTSC Analog Composite Video", or "Video" for short. You need an adapter to "Video".
Exactly which MacBook Pro (or which output Display Port) do you have?

How Do I Transmit Audio from My 2008 MacBook Pro to My 2011 Samsung HDTV?

Hello,
I'm trying to transmit audio from my 2008 late model MacBook Pro to my 2011 Samsung HDTV. My MacBook's Model Identifier is MacBook Pro 4,1 (ancient, I know). I purchased this DVI to HDMI cable which does a beautiful job of transmitting the video to my HDTV, but no audio (as advertised): http://www.amazon.com/gp/product/B000E8SY5Q/ref=oh_o02_s01_i00_details HELP!!
Thanks very much.

I figured it out! I plugged in my 3.5MM auxillary cable I use to plug my iPhone into car stereo jacks from the headphones port on my MPB to the "PC/DVI Audio In" on the back of my Samsung HDTV and voila! It worked! No additional cables (other than these two). No upgrading OS. Yay!
Here's the auxillary cable: http://www.amazon.com/AUDIO-3-5MM-JACK-AUXILIARY-CABLE/dp/B002Q3K0QS/ref=sr_1_1? ie=UTF8&qid=1330576344&sr=8-1
This looks like a great workaround to the MPB to HDTV audio problem! Hopefully my geek status is still intact. W00T!
When in doubt, try all the cables you have in all the different ports. AV hasn't changed much over the years and you can often rig things to work with what you already have. Yay for keeping cables out of landfills and repurposing!

HT204291 Airplay mirroring. Macbook 2012 retina display. Unable to see desktop on television, audio works perfectly. Both OS on ATV and Mac are running latest versions

Airplay mirroring.
Macbook 2012 retina display. Unable to see desktop on television, audio works perfectly. Both OS on ATV and Mac are running latest versions.
Firewall set correctly (allow incoming...)
When I click mirroring to turn it on, teh Apple TV screen goes blank (from its home setting)
Any help appreciated.

Hi!
I figured it out! It was a firewall issue.
I use Handsoff and I checked it before i wrote here. There was no "user defined rule" that denied the communication but when i changed to "All rules" the program displayed several rules regarding AppleTV and its IP.
So if anybody has the same problem make sure you see all rules of your firewall and get rid of the AppleTV related rules generated by the program itself. You dont need to update to the latest iOS on the AppleTV!
I hope that I can help some people with this info to fix the problem.

[SOLVED] MacBook Pro 6,2 Intel 5/3400 Card: HDMI Video OK, No Audio

I have an older MacBook with a current install of ArchLinux on it. This version uses the Intel Corporation 5 Series/3400 Chipset. I am using ALSA, no PulseAudio. I can connect it to an external HDMI output and use an external display (XFCE>Settings>Displays) and activate the video. But when I try different audio devices, I notice I have no options for HDMI audio output. Is this because I have disabled the NVIDIA card on MacBook like so with grub2 outb commands directly to the UEFI firmware ? Is there anyway to get the Intel card to HDMI audio output?

Needless to say I do not think this is possible unless you use the Nvidia card, from lots of lspci tests and experimenting with booting it on and off. I am going to mark this as solved, as I am only using the discrete IGP graphics card and do not feel like wasting juice unless rebooting to watch movies for a long time.

My Facetime audio does not work on my MacBook

My Facetime audio does not work on my MacBook, video is fine. Volume set to max, internal mic is "on", mute is 'off'. Advise

While we all have MacBooks in this forum not all of us use FaceTime. There's a FaceTime Support Community where everybody uses FaceTime. You should also post this question there to increase your chances of getting an answer. https://discussions.apple.com/community/mac_app_store/facetime_for_mac

Macbook Air Mid 2013 No Built-In Audio

Hey everyone,
I have an issue with my friends Macbook Air (Mid 2013 Model). After listening to some music through his speakers, he unplugged his Aux cable and then plugged them back in to find that he didnt have built in output or input anymore. I have tried all of the following to fix it:
Reinstall OS X 10.8
Run all of the Automation tools found in the application Onyx
Reinstall certain .kext files (AppleHDA and AudioAUUC)
Repair permissions
Re-seat the speakers in the device itself
Reset coreaudio
Resetting SMC, PRAM, and NVRAM
Clear and re-build kernal cache
Cleaned the headphone jack
Plugged in an audio interface
Reloaded from Time Machine Backup
etc...
I've literally tried almost everything in the book. The only other thing i can think of is installing a copy of Mavericks when it comes out (In October i believe). There is no boot up chime, and after running the OS in verbose mode, i can see that AudioAUUC.kext is not being loaded. Built in audio does not appear is system profiler. What can i do to fix this problem? Could it really be a hardware issue? If so, what can i do to fix it?

Test after each step.
1. Applications > Utilities > Audio MIDI Setup
    Audio Devices window
    Side Bar
    Click the Built-in Output.
    Under Mute any of the boxes checked? If so, uncheck it.
    Option click the speaker icon, if present and select Internal Speakers.
2. Plug in the head phone and reset SMC.

New MacBook Pro Unibody Jun 2011 - No Audio Device / No Output Device Installed. Please Help.

Dear All,
I have installed OSX Lion on the 20th July 2011 and the problem started with the audio device installed. Itunes wont even play and iDVD and you tube would work without audio. I have tried everything from system diagnostic re-booting back to original snow leopard on 10.6.7 including taking it for service. The audio works intermittently when I re-start my MacBook but eventually disappears back to square one. Until restarted again.
I am still under my 90 days from purchase date and the problem is I am no longer in London where I originally purchased the MacBook from - I moved to Delhi, India with my family and they don't have geniuses here only local service/ technicians who already tried fixing the problem.
Very disappointed after spending nearly £1,600.00 for this.
I don't want to go back to the local service centre for them to restart my MacBook to prove audio device is working.
Is there any other option for me like refund or replacement?
Many Thanks
Shah

Dear Lex,
Thank you for your advice above.
I have updated latest iTunes 10.4.1(10) 64 bit.
I have updated latest OSX Lion: 10.7.1 Build 11B26
Still the problem occurs. When laptop restarts the sound stays for 5-10 min before shutting down intermittently. In iTunes the music will not even run - other applications such as YouTube - it will run but no sound.
I have tried everything now and I am certain it must be a software connected issue I am experiencing only.
Please can you help.
Many Thanks

Audio too loud on my MacBook Air!

So, I just purchased my MacBook Air from Best Buy (as an Open Item since there was an awesome markdown plus coupon markdown on top of that, and 18 months financing is pretty cool too). My problem is that the sound is extremely loud on this system, especially when I have headphones plugged in. I have the master volume at the 4-5 level (out of 16, mind you), and headphones can only be set on 1 (or if using the gradual shift with Shift+Option+Vol Up/Down it would be more like .5). If I have it set to full volume, the speakers are blaring (and I'm sure I'd be permanently deaf if I tried that with headphones on). This is my first Apple laptop, and I don't have this issue with my iMac (but I've got a pretty decent set of external speakers hooked up to that, so if there is an issue I don't notice it).
I tried fiddling with the sound in the System Preferences, but all I have access to is the Alert Volume slider and the Output Volume slider (which I found is the same as using the volume hot keys). And for the Output preferences tab, I can select the headphones, but all it gives me is a balance slider, no individual volume control for them.
I've been googling and searching this issue in this Support Forum, but most of what I'm finding is about the system having the opposite problem (extremely low audio), and the few that seem to have the same problem as I do aren't really getting a definitive answer. I thought I saw one where somebody had this problem and took it into an Apple store, where they popped the laptop open and noticed that something wasn't hooked up correctly (wires hooked up wrong, or something like that). But I can't find that particular thread anymore, so I'm a bit uncertain on that - anybody know where that thread is and can I have a link?
I'm wondering if this particular MacBook Air was returned because of this sound issue. Should I take my MacBook Air in to get it looked at? And if so, should I just go into a full Apple store rather than the Geek Squad (which is more PC oriented)? I did purchase a Geek Squad Black Tie plan, mostly for the accidental coverage. (I'm a klutz).

I think I might have figured out why the volume is bothering me.
On my iMac, I have a decent set of Creative external speakers hooked up and it has an external volume/bass controler w/ headphone jack. I've set up the volume on the speakers to a comfortable level, and use the iMac internal sound control to do minor editing - which is normally set around 11 out of the 16 "notches" and that way I can increase/decrease w/o fiddling with my Creative volume control.
But when I unplug those speakers out of my iMac, I end up with the insane volume that I'm not used to (I jumped when the sound played and had to mute it. XD I think I should start video logging my troubleshooting for the lulz.) I also figured out that the system remembers the sound levels when you plug/unplug headphones/external speakers. Very handy. :3
So, I'm just used to having a fine tuned control over my sound, and when I started playing on my MBAir, I thought something was wrong. I'm probably just going to go get myself a really good set of headphones that have a volume control on them so I can get the same results I get from my iMac.
Thanks for the help! <3 I'll let y'all know if I run into anymore problems!
