Audio Output with fullsize headphones

I don't know the specs on the audio outputs for the iMac but can it sufficiently support a Sennheiser HD555 or HD595 headphones for full audio potential? I believe those cans have a 120 ohm impedance so I'm unsure if an amp is needed.

Hi, we just plug em" in direct.. You do have Audio MIDI SetUp (Utilities) - in which you can make various input/output selections....L

  • No audio output with wireless projector connection

    I use EasyMP Network Projection software to connect wirelessly to a projector. Until about two weeks ago (before Yosemite OS came out) the connection stopped streaming sound through the projectors speakers. The video works but the sound only comes out of my laptops speakers (Macbook Air) and I don't see the projectors audio output show up in the sound control panel. I know the projector is not to blame because other people can use the projector and get sound out of it. I'm also getting an error upon opening the EasyMP software that says "You need to restart your computer to enable Audio Output" but restarting the computer makes no difference.
    Steps taken to resolve issue:
    Uninstalled and reinstalled the EasyMP software
    Reset the SMC
    Restarted the computer
    Repaired file permissions with Disk Utility.

    I have outputs 1+2 connected to a pair of Audix powered monitors. I've tested the monitors with other audio sources, and they work. Also, I'm not getting any audio from the headphone jack. This makes me think that I've either got something set incorrectly with the software, or there's something wrong with the mixer.
    I also tried running Garageband with the FW-1884 and had the same problem, if that helps.

  • Audio output with aerender

    I'm encountering a strange behavior on CC's aerender that becomes different depending on the presence of ae_render_only_node.txt, even if it's not supposed to.
    I've made an example project called test.aep, with a custom output module called "QTAudioOn," with "Audio Output On" to have an audio track every time something gets rendered.
    test.w_node.mov is when there was ~/Documents/ae_render_only_node.txt, test.wo_node.mov is when there wasn't. In the same configuration, the yielded files came out different.
    test.w_node.mov was missing an audio track, that is supposed to be silent track according to the output module configuration.
    It seems test.w_node.mov was created using "Audio Output Auto" output option which was newly introduced with CC. The same process was never a problem with CS6. This problem frustrated me since we concatenate videos in order and merge the audio with other audio track programatically using MP4Box and ffmpeg. Missing audio track scrambles the result video in concatenation process.
    Is there any way to fix this problem? Maybe I could make silent track using ffmpeg, but it seems too much.
    Thanks.
    Don.
    Edit: test.aep consists of only one red solid object, nothing else.

    For those who are interested, here's how to add a silent audio track to rendered video:
    $ ffmpeg.exe -f lavfi -i aevalsrc=0,aconvert=s16:stereo -y -i input.mp4 -shortest -c:v copy -c:a aac -b:a 192k -ar 48000 -strict experimental output.mp4

  • Audio Output with firewire audio interface issue

    Hi, i have a quick question that maybe someone here can answer for me. I originally posted this in the OS X forum but someone recommended that I may get better help here.
    I have a PowerPC G5 with Mac OS X 10.4.11. I do a lot of home recording and use a Presonus Firebox Firewire recording box. I recently picked up some new monitor speakers that I run the outputs of my Firebox to and I use the Firebox as my output sound device in my system preferences.
    Everything works pretty well unless I touch one of the volume buttons on my keyboard (which I tend to do out of habit pretty often). If I do press one of the buttons the volume dips way down and I have to pump my speakers and firebox volume up all the way up to hear them. If I do this, and then happen to put my computer to sleep when I awake the computer the volume is now at an extremely high level until of course I press one of the volume buttons on the keyboard.
    The big problem is I have twice in the first two days of having my new speakers turned them way up and later in the day awoke my computer from sleep mode and had itunes or a dvd BLAST out of my speakers at a ridiculous volume.
    My question would be is there some way in os x I can disable the volume buttons from being used if i am using a different output device? OR is there a better way for me to set my system up in my system preferences?
    It was suggested in another forum that I look into the help for the Firebox unit instead of the mac so I have started to do this as well. I just thought that because everything works fine UNTIL I touch the computers keyboard it seems like the computer is making some drastic change in how the sound is being output, so I thought I'd try to find an answer here as well!
    Thanks so much to anyone in advance who has any sort of help with sound preferences and or settings!!

    This is a very good point! Thanks for your response.
    I do realize that I have multiple volume controls going on here in a chain. First my computer, then the Firebox interface, then my speakers have volume knobs...
    But what I am seeing is when I first press a volume key on my computer (even if it is the VOLUME UP key) there is drastic lowering in volume. Only until I put my computer to sleep, and awaken it does the volume return to a normal level.
    It seems that when I am pressing the volume on my computer it is activating something on the mac's end... or changing the way the sound is being output.
    Again all of this could be avoided by me not pressing those 3 keys on my keyboard... but old habits die hard! so if there was a way for my mac to give total control of sound output over to my firebox that would be best.
    any more help is greatly appreciated!

  • Dual use audio output HDMI and Headphone Jack on MacMini 2010

    I am trying to use both the digital HDMI and analog headphone jack at the same time. My indoor home theater system use the HDMI and my outdoor amp and speakers are linked to the analog headphone jack.
    Unfortunately, I can't figure out how to get both to work simultaneously like I had on my AppleTV. I was actually using the toslink and the HDMI on the ATV.
    Anyone have any luck getting both outputs to feed at the same time, maybe by 3rd party software, on the Mac Mini 2010

  • How listening audio output with console digidesign 002

    i have conncected the fcp5 with the digidesign 002. I have made all the necessary settings, that provide the connection, through audio/video settings/user preferences etc... Though, when i put something to the canvas, i can listen from the speakers, but the channels of didgidesign don't communicate with the audio channels in fcp.2)when i do log and capture from the cam, the logged footage has sound, but i can't listen to it, when the sound is connected via digidesig. It seems that something is wrong but i don't know what. Does anyone knows?

    You have to use the Digi-002 in Standalone mode, as a mixer. Press the standalone button and then select 'Yes'.
    I connect the optical audio cable from my G5 into the optical audio in the back of the 002. You'll have to read the manual to make faders 7 and 8 'listen' to the optical port rather than the XLR inputs. And then in System preferences on the MAC, the Audio Out would be Optical Digital-Port out.
    The only time I use the 002 in it's regular mode is i) when I'm using Pro Tools, or ii) when I'm using Garageband and using the 002 as my audio input device.
    Hope that helps.

  • Audio output with monitor conneted

    i ahve a macbook pro and whenever i connect it to my cinema display then hook up to speakers i get this feedback on audio system. if i unplug monitor feedback dissapears. does any1 know a way to solve this?
    Message was edited by: mark2kay

    Maybe you don't really mean feedback. Are you hearing a very loud squealing? That is acoustic feedback from an open microphone near speakers.
    Do you hear soft varying buzzing noises? That seems to be a ground problem with external display and external speakers connected. See this thread:

  • Premiere CS4 Audio Output with Decklink

    Hi,
    i found serveral posts in the net for my Problem, but no solution.
    Were on a WindowsXP machine with Premiere CS4 and a Blackmagic Decklink Card.
    If we choose a Sequence-Preset from Blackmagic Decklink (which is important for us) and choose the internal Soundcard for Audio Playback,
    we dont hear anything. The Audio is routed through the Decklink. We have tried everything to achieve that that audio will be played through the internal Soundcard, but it seems as if the Settings are overwritten by the Decklink Preset.
    In CS3 this Problem doesnt exist.
    Many thankx in advance for your help....
    Sascha

    oh, we have the actual CS4 Update and Deckling Driver installed.

  • Processor noise with audio output?

    I attached my Mac book pro to my 40" LCD TV along with an audio output from the headphones out to the input on the TV.
    What I noticed is that the "processor whine" that we all complain about that seems to cease when we are running things like photo booth, and intensify when we disconnect the AC adapter, is projected through the audio of my TV!!!!! When I mute the TV, away goes the whine. Strange huh?
    I don't know if this is a new revelation, or a known reproduction of the problem.
    So my question is, do you think there is a relationship between the poor output on the speakers (very little sound on bars 1 through 7) and this processor whine we complain about?
    I was generally happy with my MBP and would ignore the whine until my TV set amplified it.
    Do any of you also think that Apple would replace my MBP for this and the many other complaints? (Screen inverter defect, generally hot, and this noise output via cable)
    Thanks for your input on my future with this computer, like I said, I've always been happy with it until this output problem.

    My guess as to what causes the whine is this:
    There are many small copper traces on the motherboard carrying signals. There are two traces in question. One carries the power for the processor in low power mode. One carries the power to the sound card (or from the card to the speakers). Those two traces are too close together. So when power flows through the proc trace it induces electric current in the other trace, which causes the sound we hear from the speaker.
    It is a problem of the design of the MLB. So the fix would be to isolate the two traces.
    Just my idea.

  • Why MBA (Mid - 2013) doesn't support with Bose Headphones for Audio Input

    I just bought two MBA 11(mid - 2013)  and MBA 13 (mid - 2013) two week ago and I found out that it doesn't support bose audio headphone (MIE2i mobile headphone) for audio input. So I am having experience for audio input with it. When I am having skype or recording, the voice go slient if i use that headphone as external microphone. All of my friends who are skyping with me can't heard my voice if i am doing skype with my MBA.  Audio output is fine though, you can hear as usual in headphones. Internal microphone works though,  but it is not good for privacy though.
    Thus, I went to apple store (Five ave) to trouble shoot about it, they said that is because Bose has noise cancelling, (BUT Bose MIE2i doesn't have noise cancelling though). They gave me two ear buds of apple ipod (one is outdate version & another one is latest version - that representative sucked, because she doesn't value the customer, she gave me outdate ear-buds, but i didn't urge with 3 dollars ear-buds), apple ear-bud works for audio input and output, however apple ipod ear buds are suck, it hurts the ears all time if you wear for 1 hrs. that's why I use quality headphone such as Bose headphones. Unfortunately, my bose headphone is not compatible at all.
    Is there any one having experiences with audio input with your headphones when you are using skype or audio recording. Which headphone is compatible with your MBA for input/output?

    The MacBook Air has a single headphone port. The microphone or headset in question must be of the three-ring variety, just like Apple’s headsets ......, the Macbook Air has the “headset” port,  not a conventional 2-ring mic and speaker port.
    Many are using this,

    Youre likely going to need to get a USB headset to use with your Air.   OR, standard headphones plus a USB Mic.

  • Audio concern with optical out (headphone jack)

    According to Apple, unless I am blind, Macbook pros from 2008 cant support 5.1 via toslink in the headphone jack:
    (Copied from Apples Tech spec page)
    Connect external speakers, headphones, or optical digital audio equipment. The headphone / line output jack accommodates optical digital audio output, analog audio output with a 24-bit, 44.1-192 kHz D/A converter, *digital audio output up to 24-bit stereo and 44.1-192 kHz sampling rate* and supporting encoded digital audio output (AC3 and DTS). For analog headphone / line output a standard audio cable with 3.5mm metal plug should be used. For digital audio, a standard toslink cable with a toslink mini-plug adapter can be used.
    Yet I read how people say they get 5.1 working. I don't get it. Apple says only up to 24 bit stereo.

    Look in the Audio MIDI Setup utility when connected to the receiver and see if you can select it there. IIRC you must have a DVD encoded in surround sound in order to have the Mac put out the surround audio.

  • No Headphones Audio Output T440

    Hi,
    I have a Lenovo T440 running Microsoft Windows 7.
    I cannot get any audio output on my headphones. The speakers work just fine. The headphone are in perfect condition and I have tried them on other audio devices. I have also tried to use other headphones just to be sure my primary headphones i not the issue.
    The Realtek Control Panel recognizes the headphones as soon as they are inserted into the headphone jack.

    This thing has been going on for quite sometime now for many people but apparently no forum has posted a solution. Would appreciate any help.

    Classic mode should make the headphones option disappear as it autoswitches on attach.
    Try a bootable Linux live environment; if it doesn't work there, you might have a damaged headphone jack.

  • Can't change audio output in System Preferences

    I have installed an M-Audio Firewire Solo interface on my Mac Mini and have made it my default audio output device in System Preferences. When I go to change the audio output back to "Headphones" (the built-in output on the computer), it will not allow me to do so. I click on Headphones, close the window, reopen the window, and the Firewire Solo output is still selected. I'm guessing there's an easy solution to this?

    Welcome to the Mac and Apple Discussions.
    Open the Preferences folder in the Library folder on the hard drive and look for the files com.apple.audio.DeviceSettings.plist and com.apple.audio.SystemSettings.plist and perhaps any others. Move them to the desktop and restart or log out and in. The system will rebuild them when it starts up again. You might try removing them one at a time so you are able to identify which is the corrupt .plist file, if in fact it is a .plist problem.
    If that doesn’t fix anything, look for similar files with .audio.xxxxxx.plist in your Users Preferences folder: Users/yourusername/Library/Preferences and try removing those. The .plist files usually can be removed without causing problems as they are automatically rebuilt. If it does cause a problem, you can move the originals back to their respective folders from the desktop, replacing the ones that were reconstructed after the restart and you’ll be back to the way it was before you removed them.
    And then I’m out of ideas. But keep posting until you get it solved. There are a lot of very knowledgeable people on this forum. If you don’t get any response for a while, respond to your own post with the word “Bump” to get it to the top of the stack again.

  • How to get the Mac Mini Digital Audio output at 192kHz?

    I have a mid 2011 Mac Mini (and love it). According to http://support.apple.com/kb/HT4806, "The headphone / line output port accommodates digital optical audio output, analog audio output with a 24-bit, 44.1-192 kHz D/A converter, digital audio output up to 24-bit stereo and 44.1-192 kHz sampling rate and supporting encoded digital audio output (AC3 and DTS)."
    So there is digital audio output to 192 kHz but how do you configure it to work? Using the Audio Midi Setup Utility, I can set the sample rate to 96000 Hz -- but it won't go higher to 192kHz. Anyone know how to do this?

    That is in some ways confusing.  For the analog output, the
    internal DAC can support 24 bit/192Khz audio data.  It does
    require an application that has the capability of playing back
    such material.
    The TOSLINK optical standard does not support this data rate.
    It has nothing to do with the Mini, it is the standard itself.  The
    TOSLINK optical spec is 96 kHz, 24 bit stereo (uncompressed).
    The mini will however support multichannel, 24 bit, 192 kHz
    (uncompressed) via the HDMI interface.  Also, again,
    the playback software needs to support it.
    Just as a final note, unless the source material has the
    higher sample rate format, there is no benifit to outputing
    at the higher sample rate, especially if the source some
    lossy comporessed format (mp3, aac, Dollby and DTS
    non-HD formats).
