IMac :: Unable To Activate Sound Output / Connected To HDTV?
Nov 4, 2010
I have an iMac 27 and I want to connect it to a HDTV samsung 46 full HD. I have conected from displayport to HDMI and i get the screen. But at the same time I have connected a 3,5 minijack from the computer to the RCA audio in of the TV but I dont get sound. I have checked the config of the TV and I dont find any place to activate it. Then, talking about the screen. I have few questions.
How can I stop the screen on the iMac and work only with the HDTV?
How can I config that the windows on the tv have bigger letters while they keep on the same way on the i Mac's screen?
The tv is kind of far away and is difficult to see the letters.

I just ordered the 27" iMac. Trying to figure out the best way to do output to TV. There 2 approaches I would suspect.... but since the 27" display signal is 2560x1440 (HDTV can only go up to 1080p).
I don't know of any adapter or TV that can support this resolution. Will the signal come in only partially displayed
1) Wireless
Atlonas - HDAIR wireless usb to HDMI/VGA with audio
http://www.engadget.com/2009/11/21/a...gains-audio-u/
pros+: one connection for audio and video, usb, easy setup, hdmi out, wireless
cons-: reported sucky framerates, max res is 1440x1220 (720p), not mac compatible (so will req bootcamp/vmfusion/parallels - windows).
2) Wired
Would need the following
mini displayport + toslink audio + usb to hdmi out
1) [url]
50ft hdmi cable
2) [url]
I heard 50feet is about the limit of HDMI for 1080p if you don't want to mess with amplifiers to correct signal lost.

I can feed sounds into my iMac with line input but no sound comes out vis internal speakers. I can record the input sound using Amadeus and play through gives me sound output. When not using Amadeus although input is set to line in and output to internal speakers no sound comes out. There appears to be some internal disconnection between input and output.

I just got this new iMac that I got used and the sound on the computer does not seem to be working, I have tried doing what the computer tells me and going into System Preferences and selecting the sound option, but the sound seems to have been permanently disabled and shows that there are no output or input devices available, when clearly the monitor has speakers. whats more, is that the volume icon does not show up in the menu bar even when I select that I want it in the menu bar.

My sound keeps turning off. When I check the settings, the output device switches randomly between Internal and Digital output. I have no idea where the Digitial Output is coming from and this started about a month again. It switches randomly and then I loose all sound for a few seconds. Sometimes it happens once then stops for a few days, other times it switches back and forth for 5 min. No idea!!!

I'm looking to output my mac pro to my HDTV (cheap mans video output monitor). I got a DVI to HDMI connector and all the females and males seem to agree to the point that its all connected up rather well. Only problem is that my mac pro only detects my computer monitor, not the TV that I've attached. Things to note:
* I normally run two monitors at 1920 x 1200. I just removed one and replaced with DVI > HDMI adapter going to TV.
* I can get the display to work in windows (although for some reason, although it outputs to the TV via HDMI the other screen stops working) so the connectors are working fine.
* I tried hooking up the monitor to the port, downgrade the res to something below 1080, then connected the TV again, no result!
* I couldn't get 1080 resolution on my screens as its not an option in the display preferences.
* Before anyone states the obvious (at this point even that would be helpful) I restarted every time I attached another display.
* I have searched google, apple support, and these forums and I feel im going insane.
To summarise, I haven't seen my mac on the TV yet. Its staring back at me with a blank black.

I am looking for a solution for sending dv and hdtv quality video, ntsc, out of my macpro to an lcd monitor.
Basically, I want to be able to have a real time program output from my fcp timeline while I am editing.
Previously, I have been going firewire out to my camera, then using the camera as an a/d converter, going composite to an external monitor. I would like to bypass having to use the camera in this way.
It would be nice to find a PCI card (or whatever they're called) that has s-video and/or hdmi and/or dvi, so I can plug directly into the lcd. I just want to make sure, though, that I can select this output within fcp.

I just got my iMac yesterday, and its been awesome, but I have one question. The classic "bong" sound at startup, I know that is the result of a successful POST, but mine didn't do one after the 1st startup. I had speakers plugged in to it when I started up the 2nd time, and no sound. I unplugged the speakers, and I got the sound. Is that normal or do I need to contact Apple? I jut want to make sure nothings wrong with my iMac. I checked the POST results in System Profiler and it said Passed.

I am new to macs and recently purchased an imac. My problem is when I connect a usb device such as my iphone or camera there is no sound played signifying that it is connected. I am used to using windows where a noticeable tune it played everytime a device is connected or disconnected. I have tried looking in setting and such without much luck. Is there anywhere else that can turn this feature on??

For some reason, I can't get Logic Express 8 to output audio to my Mac's attached speakers. It outputs fine through my M-Audio interface, though, but I'd just like to listen without headphones.

This started happening randomly earlier tonight, and I haven't managed to find a fix just yet.I was encoding a video file for quite awhile (I don't think that parts important, but I thought I'd include it anyway) and then I tried to play a youtube video. I noticed there was no sound, so I tried to up the volume using the Volume Up key on the keyboard. The volume visualisation appeared on the screen like normal (albeit a bit laggy), but the sound still didn't change, neither did I get the usual 'click' noise you get when you change the volume.I went looking into the sound options in the system prefs. only to find that the Output Sound device was headphones. For a test I plugged in some headphones to see what happened and, low and behold, the Output Sound device changed to the Internal Sound and my speakers were working again, but only with the headphones plugged in.

I have a 2010 Macbook pro and I just ordered a minidisplayport to HDMI cord. I was able to get it all set up to my Sylvania 22" HDTV HERE but I can't seem to get the resolution right. I've tried multiple resolutions both via the control panel and NVidia's control panel. Keep in mind I'm running Windows 7 via bootcamp. I'm able to get the resolution to look pretty clear, but by doing so it cuts off the edges of the screen, where as if I get it so it all shows up on the screen, it doesn't look as clear.

Got 2011 Mac mini and connected via HDMI to 15 months old Samsung 46 inch LED TV using 1080p and 50Hz. From start (dec 2011) I have had the problem that occationally (>50% of the times) the TV starts to flicker heavily. It is "war of the ants = cannot see anything" on the TV for like 3 seconds and then I can see the desktop clearly for around 3 seconds an then it is back to the flicker.screen. It keeps on like that until I shut-down and restart the Mac mini. Sometime restart works an sometime it does not. Anyone with similar problems that know what to do?

I woke up this morning and tried to watch a linked video on a webpage. I saw the video, but there was no sound (this had not been a problem the evening before). I am using USB soundsticks, so I checked to make sure that they were plugged in, and they were. I opened iTunes and sound came through the Soundsticks; I switched to the internal speaker and it worked there as well. When I tried the same with another embedded video, however, I only got sound from the internal speaker.
Has anyone had a similar problem or does anyone know how to fix this?

I'm using a DVI->HDMI cable to connect my Powerbook to my Sony LCD TV. The Sony's native resolution is 1366x768. For some reason my Powerbook doesn't want to switch to this resolution. I can get 1280x720, but this leaves a black border around the images the whole time.
I've tried setting a custom resolution using the trial version of SwitchResX but to no avail. It won't do it.
Anybody have any similar experiences and possibly found a fix?

I have a 27" iMac and an LG 47" 1080p HDTV. I just bought the Griffin Video Display Converter, which is certified by Apple to pass both video and audio from the mini display port on the late 2009 iMacs. Whenever somebody turns on the HDTV the iMac's screen flickers the color blue on and off, sometimes staying that way permanently. Permanently the color blue that is. The only way to get out of it is to turn the iMac off and then back on (restarting it).I have the ?Mirror Displays? checkbox checked in the ?Display Preferences?. When I uncheck that box it treats the connected HDTV as an extension to the iMac display, whether the HDTV is on or off, which makes my cursor disappear off one side of the screen. This is why I leave mirroring on.

pretty new to the Mac side of things. I got my MBP about 3 weeks ago I think. I got a mini display to hdmi adapter (off ebay, so this may be the problem). I hooked it up to my laptop and tv and it took me a while to find the mirroring box but I got that working so what's on my computer pops up on the tv. I go to play a tv show, and the sound is just on my computer. I went under system pref and sound but only "internal speakers" is available for the output. Am I doing something wrong? Or do I just have a cheap adapter?

how to get sound to play on my TV from my laptop for several days now. I bought an Mini Display Port to HDMI converter (Kanex Iadapt) off Amazon that is supposed to have audio support. I connected it with the HDMI cable to my TV and changed my display settings to mirror and the picture comes up fine but when I tried to change the output in sound settings to my TV my TV didn't even come up as an option. I went out and bought a Y audio cable figuring my laptop may be older than 2010 and needs an additional cable, plugged the audio cable into the same HDMI outputs in the TV and still no sound.

I would like to connect my Macbook Pro to my hometheatre via HDMI. Normally no problem with the mini display port and an HDMI adapter, but the port is already used for the 27" cinema display... Is there another adapter available that let`s me connect both, an HDMI device and the cinema display to my Macbook? I only care about the sound - I want to get digital sound to my receiver. (I am not interested in the solution via airport express and then connect via analogue audio cable - I am looking to get a digital sound signal all the way through...) about Macobook Pro: mid 2010, 17", Processor 2.53 GHz Intel Core i5, Graphics NVIDIA GeForce GT 330M 512 MB)

I recently bought an ACD which I hook up to my MacBook. I watch videos and movies on it late at night so instead of playing it through the speakers I prefer to play it through headphones so I don't keep everyone up.
This works great with iTunes. I plug them into my MacBook and off I go. For VLC, however, it STILL plays the audio through the speakers even though my headphones are plugged in.
How do I change it so the audio plays through the headphones when plugged in using VLC instead of the speakers. (Jeez, you'd think this would be basic functionality. >_>)

I picked up a really cool wireless USB speaker set and want to use it with my current gen iMac running Snow Leopard. Problem is that as far as I can tell, and I've done some searching, that it's either the USB audio, or my internal iMac speakers, one or the other - not both.
could use both outputs at the same time? Internal speakers and the wireless USB ones?

This question will probably make me look like a total noob. But I can't find info on the Apple website. I've purchased Apple Care from a third party seller. Now I got the code emailed, without instructions. How do I activate this protection plan?

So I tried closing all my apps and everything, and even set the Energy Saver preferences down to go into sleep mode after 1 minute of inactivity. But it still won't go to sleep! The screen will, but that's all. It's a mid-2007 MacBook running 10.5.8, for the record.

I upgraded from Yosemite 10.10 to 10.10.1 a bit over a week ago. I am using a Mac Pro (Mid-2010). iMessage worked fine after my upgrade from Mavericks 9.5 to Yosemite 10.10. When the 10.10.1 upgrade came out, I upgraded. Now, I cannot activate iMessage. I get a message that basically says my Apple ID is not recognized. The same Apple ID and iMessage work fine on my rMPB (late 2013) running the upgraded Yosemite 10.10.1. I have not, in all my attempts to activate, received the error code that some folks mention.

I'm unable to activate iCloud Drive on my MacBook running Yosemite 10.10.1. Some documents eventually show up in my iCloud Drive, but I'm never able to create new ones or download new ones created e.g. on the web or on my iphone. I disabled iCloud Drive for now, and whenever I try to re-enable it I get the following erorr in the Console:cloudd: SQL error: 'DELETE FROM CSChunkTable WHERE ct_iid = 596', (11) database disk image is malformed
which is repeated for 100s of ids. iCloud Drive works on a guest account and on other devices. I already tried signing out of iCloud on this Computer, but without success.
Is there any way to "repair" this malformed database disk image?
