Audio Out not owrking..

The headphone socket on the front of my Mac Pro has stopped working..
The loudspeaker 3.5mm socket at the back never worked, but the front socket stopping suggests some kind of hardware failure? Anyone ever had this problem or could suggest how to diagnose it?
Many thanks

Apparently, there are a number of strange things about the way the Mac Pro handles sound output. I have external speakers attached to my Mac Pro, and line out is selected in the sound preferences pane. All of the sound comes through the speakers except for the startup chime. It is only heard through the internal speaker. This never happened with my earlier PowerMac 7300 or Dual 2.0GHz G5. Someone suggested that this is normal behavior for the Mac Pro. If so, it is the first Mac I have ever owned that acted like that.

  • USB audio out not getting to DAC

    Just set up my Macbook late 2007 OS 10.7.5 to a Denon DA-300USB DAC.
    I'm successfully playing files out of JRiver Media Center software via Mac's digital audio out through an optical audio cable. But optical audio has limitations on bitrate, only to 24-bit/96khz.
    I want to use higher rates and have some higher res files. The DA-300USB can process up to 24/192 and DSD files using USB.
    When I connect the DAC using USB and power on the DAC, the sound preference pane adds the option "Audio Out High Speed USB," which is what I select. This indicates the computer is seeing the DAC.
    But when I play a file, the DAC display reads "unlock," meaning it's not receiving audio. And the sound plays through the internal speakers, Ugh!
    Denon says no driver is needed for this device -- indeed the computer does detect a USB audio connection when the DAC is on.
    Is there something I'm missing?

    According to Crutchfield, this DAC can only process ALAC up to 96 kHz.  Can you get lower res files to play using the USB connection?

  • External speakers - audio out not working

    I have these old Creative speakers with a subwoofer that I often use with my macpro laptop.
    I just bought a 4K Mac Pro tower, and on the back, I see two similar jacks, one of them with a little speaker icon, which I assume, means thats where I should plug the speakers in.
    I plug my speakers in there and they don't work. I plugged my speakers into the little jack next to it, and it still didn't work. I did this extensively. Stupidly, even.
    I plug my speakers in the headphone jack on the front and they work just fine.
    The speakers have always worked, we used to use them as part of our home stereo system, and they were plugged into an audio out jack. I've never had a problem with them.
    Is there something wrong with the audio out jack on the back of the tower? Is there a way to fix this? A driver? Software? It's not a huge deal, but I would rather keep ugly cables behind my computer.
    Thanks!

    Do you know if there is a way to have the sound output coming from both analog audio outputs at the same time - from the headphone jack and the back jack? I'm amazed you can't have both working at the same time.

    you can take the output from any application, or all system output, and use the "Auxiliary Device Output" effect to send it to a second output device.

  • NEO2 Audio out not working & Mobo Review

    Everything finally working great! Have all the latest live updates and after some hiccups getting the system built, it appears to be everything MSI promised it would be.
    I have 3 80 Gig SATA drives, P4 2.53 GHZ, 1 Gig Corsair ddr400 memory in dual mode, 1 Panasonic DVD RAM, 1 SAMSUNG dvd/cdr, 1 Internal multi card reader, Realtek 5600 128 meg video card. Canopus DVSTORM2 hardware/software editing solution. All IRQ's are happy and finally set and there are no conflicts. The system is fast and has not crashed since installing the latest drivers and patches.
    The only bad news is,... my audio out is not working! The front panel headphones work, but I can't get any audio out of the back ports. I have the Audio 6 channel port installed, even though I only need 2 channel stereo. I have played with all the settings, and still get nothing! I need also to get audio into the back, which is also not apparently working. All the devices say they are installed and working properly, I just can't get any sound. :O
    So.......... Either someone on this thread has some options for me, or I'm off to get a audigy sound card, but I feel I'm pushing it with all the other system devices and IRQ's I'm using. So I would like to use the built in audio. Any help is appreciated.
    Also a note... I can hear in the headphone out, a real presence of the SATA drives spinning and reading, it definitely is not a clean output, with the high end drives, they are sooo fast they create electrical ambient sound effects that are loud and annoying! unless listening to R2D2 on steroids is a desired experience!  :D LOL! Perhaps another sound card would bypass this also. As always.... pushing the limits of technology, hey and I haven't even started overclocking any default settings yet!
    Anybody have a shot list of settings that might be useful?
    Thanks in advance for your input.

    Check the front panel audio connector. There are usually 4 pins which need to be shorted to have signal output directed to the rear audio ports. The manual will give the exact pins to short. I think you'll find it's pins 5 & 6 (right channel signal in & return) and pins 9 & 10 (left channel signal in & return). Basically, if you use the front audio header, the rear audio ports wont work.

  • Digital Audio Outs not mentioned in manual.

    I have a Pavillion p6140f PC. Below the monitor connector, above the mouse and keyboard inputs are "Digital Audio Out" RCA jacks.
    My manual doesn't mention these, whatsoever.
    I tried plugging them into my Yamaha mixer inputs with no success.
    Is there a certain driver needed to operate these?
    I recently reformatted the PC. It used to be Vista, then was Windows 7 Home and is now Win7Premium 64bit.
    Any advice would be appreciated.
    Thanks.

    Have you plugged in the HDMI cable and connected it to a device such as a LCD display ot HDTV? 
    Have you set the input on the TV or display to Computer?
    Have you checked in the  Control Panel in Sound to see if it shows ready? ( that would mean you had successfully installed the driver for your notebook's display)
    Does your notebook have switchable graphics or only the Intel Graphics Media Accelerator 4500MHD inbuilt video solution?
    What is the installed operating system  for your notebook?
    Please answer all  of the questions if you really would like soome help with this.

  • MacMini HDMI Audio Out Not Working

    Greetings all,
    I have a 2010 Mac Mini plugged into a Yamaha RX-V71 Receiver via HDMI.  The receiver is plugged into a Samsung TV via HDMI.  The image displays correctly onto the TV however the audio only plays through the Mac Mini's internal stereo.  When I go to System Preferences -> Sound - > Output - my receiver is not listed.  The only items listed are the Mac Mini and the Samsung TV.  When I go to Applications -> Utilities -> Audio MIDI Setup the receiver is not listed only the Mac Mini and the Samsung TV.
    I have swapped out HDMI cables.  Mac Mini is updated to Lion 10.8.2.  The receiver is on and I have tried restarting the TV, Mini and receiver multiple times in different orders.
    Does anyone have any suggestions or a fix for this?
    Thanks!

    This is the same for my setup.
    Have you tried selecting tv hdmi as your output device?
    That is what I select to play through my receiver.

  • Optical audio out not working (incl the solution for me)

    problem:
    new 2011 Mac Mini, 2.5G
    connecting to
    a) TV via HDMI
    b) to a D/A converter and amplifier for a bit better music output
    This worked perfectly for my previous MiniMac that I replace due to my need for speed.
    Now, I could see some red light at the end of the optical cable, but the D/A box did not recognize a signal?
    Furthermore, the Sound switch in Settings would only make the TV play.
    solution:
    after a lot of troubleshooting at the Genius Bar in Beijing (big thanks for that ... the shop is terribly crowded and they never manage to keep the appointments), we found the optical cable to be faulty .... it was apparently bent too much and still had some throughput but not enough to make the receiver read it.
    Nasty one!

    I just purchased this exact same receiver (used). Same issue with Apple TV. Anyone ever figure out to make it work correctly? Thanks.

  • What Kind Of Connectors for Audio Out?

    My Mac Pro is a 2-2.8g Quad, and it's kind of in a position right now where I can't clearly see, so can anyone tell me what kind of connector I need to grab the audio out (NOT DIGITAL) and connect it to another device?
    Thanks
    Tom

    These are Stereo-capable.
    Stereo jacks have a tip and two rings.
    Mono jacks the same size and shape have one tip contact and only one ring contact.

  • Optical digital audio out?

    does any one have optical digital audio out to a receiver working? it doesn't work for mp3 through itunes, video purchased on itunes, cds or dvds. works fine with the same setup and a previous generation macbook so i know it's not the receiver or cable.
    my fear is that this is a defective design issue related to the displayport hdcp issues. hopefully, my hardware is just malfunctioning.
    i was on the phone over an hour with apple troubleshooting, but no one had an answer to the hdcp question.
    thanks.

    i took my macbook up to the apple store to the "genius bar". after a few minutes, they just decided to replace the entire macbook. fine. after i got home, i immediately tested the digital out port. it works! fantastic. unfortunately, throughout the course of the night i continued setting up the new macbook. i later try the digital audio out and now it's not working.
    this morning i'm trying it again and it's working, briefly. i've found that by moving the cable around near the output jack that the sound will come and go. i tried a different cable with the same results. although it seemed to work less frequently. both cables in different devices (including a previous generation macbook) work fine.
    i've also noticed some of the comments on this forum and others (i think they were referring to different notebook models) about people having problems with the internal speakers not reactivating after unplugging headphones. my guess now is that the headphone jacks are just poorly designed, manufactured or i'm just unlucky.
    i would think it's definitely not an hdcp or other content protection issue.
    i guess i could exchange for another macbook, but with 2 having this problem it's seeming less likely another one will work out. i guess i could just be really unlucky and maybe 3rd times a charm. my only other alternatives as i see it are returning it or just living with the digital audio out not working (annoying, but everything should work on a $1500 laptop).

  • I have a mid 2009 Macbook Pro and i know the Mini-display port does not support audio out but does it support HDMI out? or do i have to buy a Mini-display to DVI and then a DVI to HDMI adapters?

    Run MDP to HDMI for picture. Use a cable like this to run sound from your audio out on your Mac to your TV's audio in.  That's about all  you can do.

  • AC charging cradle w/ audio-out does not exist?

    I've just spent hours trying to find something that, logically, should be available in plenitude, but I could not find one in existence.
    I would like an *AC charging cradle with an jack for audio-out* for my ipod touch (2g).
    Simple? I defy anyone to come up with one.
    There are cradles that charge through USB that have audio out but mine needs to be set up away from my computer so USB doesn't hack it.
    I did find exactly what I'm looking for but it was made in 2005 for earlier ipods, by Kensington, so some one at some time had the right idea.
    I'll probably just get an AC charger and then just use the ipod's audio-out, but this is hardly an elegant solution.

    What's wrong with the Apple Universal dock (http://store.apple.com/us/product/MB125G/C?fnode=MTY1NDA0OQ&mco=MTA5MjU2MTM) together with the Apple USB charger (http://store.apple.com/us/product/MB352?mco=MTM3NDk5NzY) and a cable.
    I use this combination all the time to dock my iPod Touch, charge it, and play music through my Bose speakers.

  • Blue Tooth paired but SONY DR-BT50 HEADPHONES not connecting for audio out of iTunes

    Blue Tooth paired but SONY DR-BT50 HEADPHONES not connecting for audio out of iMac
    Running Lion on intel based 27" Jan 2012 machine
    The Sony Bluetooth Headphones work well with iPhone 3Gs for music and phone but I cannot get audio out of the Desk Top Machine eventhough the headphones are paired - they do not seem to connect. I have selected them as audio out phones in Blue Tooth options but nada. Any thoughts?

  • My audio does not work on my pavilion dv4. i just bought this laptop a few days ago. what's going on

    my audio does not work on my pavilion dv4

    This worked for me.
    Hold down the option key while using the Finder “Go To Folder” command. Enter ~/Library/Preferences/com.apple.dashboard.plist.  Move the .plist to your desktop.
    Log out/in
    If it works, delete the .plist on your desktop.
    If  the same, return the .plist to where you got them from, overwriting the newer ones.
    If you prefer to make your user library permanently visible, use the Terminal command found below.
    Show User Library
    You might want to bookmark the command. I had to use it again after I installed 10.8.4. I have also been informed that if you drag the user library to Finder it will remain visible.

  • MPEG4 video from imovie is sluggish and audio out of sync

    Hi y'all,
    I am new to this. So I need some hand holding here. I am working with video that was exported in MPEG4 video from imovie on a mac.
    The Camera I used is a Sony FX7 HD camera with SD tape.
    So Now I am trying to edit the video using Premiere Pro CS3 creative suite.
    Import into CS3 is fine. Playing the imported video in the source monitor is fine as well. All looks well.
    However, here are the challenges I am having:
    1. When I try to play it in the Program monitor its very sluggish. Audio plays fine but picture lags behind.
    2. And once I edit the the video and try to export it as flash video or as a windows media, the video and audio are out of sync.
    The video is choppy as well.
    Details: source video is 720x480 and trying to export to 320x240
    My project details are:
    DV-NTSC standard 48khz
    Video is 10 min long

    OK, not my choice of workflows, but... I assume that the MP4's are H.264 encoded. There are many of these. Three common ones are Lead, MainConcept and Apple. Some find that one works better than the others. These are not the ONLY versions, but are common. You might want to explore others, depending on which one you have installed. G-Spot can tell you which you have.
    Next, you can Render your Timeline, to get things as smooth as possible.
    Note that the MP4 files are heavily compressed already. Quality has been lost, and there is nothing that can be done about that. When you Export to, say DVD, you will recompress that material, and loose even more.
    In the future, have your Mac-person do the Capture to .MOV [Animation CODEC]. Or, do it yourself to DV-AVI Type II w/ 48KHz 16-bit PCM/WAV Audio.
    Not sure of any other ways to get the MP4's playing more smoothly. Much will depend on both your CPU and on your system's I/O sub-system, i.e. your HDD's, their size, speed, controller type and how they are utilized.
    Good luck,
    Hunt
