NO Audio in System Preferences

I accidentally deleted the audio icon under the system preferences and the audio plist under library settings. I was trying to get rid of an astound audio plugin i downloaded from mac.com that always pops up and tells me to buy the software even after the trial was done. What do I have to do to reinstall the my audio? Right now I cannot hear or cant use the built in mic because I have no audio options.
Thanks!!!

Hi Moor,
Try looking in HD/System/Library/PreferencePanes.
Is the Sound.prefPane still there?
Edit: If it is still there, double clicking on it should bring up that pane and perhaps re-situate it back in System Preferences.

  • Hi i upgrade from lion to mountain lion to day on my mini mac,Since the upgrade i am getting no sound through my HDMI cable which was working fine on lion Checked the midi audio settings and system preferences to out on HDMi nothing no sound whats so ever

    Hi i upgraded from lion to mountain lion to day on my mini mac,Since the upgrade i am no longer getting sound through my HDMI cable which was working fine on lion Checked the midi audio settings and system preferences to out on HDMi nothing no sound whats so ever.Any one any ideas?
    I use a samsung TV for my monitor via HDMI.Tried all the system Audi setting nothing .Head phone and internal speakers are fine.

    Similar issue; Audio was working fine on Lion, now not on Mountain Lion. Have a Macbook Pro early 2011 with AMD Radeon HD 6750M, connected by thunderbolt through a Lacie LBD to a mini-displayport to HDMI adapter (n.b. same problem when not going through the LBD) to a Pioneer VSX 521 AV receiver. For me when I go into audio Midi settings all the volume sliders for the displayport device are greyed out and at zero. But when I click 'configure speakers', it's able to send out the test signals to each speaker. Part of the problem could be that I'm not getting the option to put out 6channel sound, only 2 or 8 channel. Since my system is Dolby 5.1, and I only have 6 speakers, I would have expected the 6ch option to be available. But I imagine there's more to it than that. Elsewhere someone has suggested playing with Remote Interactive over HD on an Onkyo device; I'll see if there's something similar on the Pioneer that can be changed. Any other suggestions welcome.

  • There is no audio output on my MBA in the system preferences-sound folder. Therefore no sound comes from my computer. At the same time this happened, any streaming video stopped playing after 11 seconds, as well as iTunes will not play any song. Help!?

    Hello everyone.
    i have a 15" MBA circa 2011 running Lion 10.7.5 and my sound has gone, There is a no sound circle on my volume display and in system preferences sound my options for output is empty. At the same time this happened I noticed 2 things: 1) itunes would not actually play any audio track and every video i streamed stopped after a few seconds (usually 11s) but not always.
    I have tried following some tips I have found online like going into MIDI and fixing the problem there, restarting in safe mode. Resetting with PRAM (or something that sounds like that).
    Does anyone have any insight on this? At this point i'm thinking it's time to reload Lion but I don't really know how to go about that without losing all of my files.
    Please Help
    Thanks

  • With 10.2 I can only use system speaker output for audio, NOT my RME FF400 I used previously. The FF400 works fine with other apps. How can I set this device in FCP 10.2? (it is set in both system preferences and midi)

    With 10.2 I can only use a system (e.g. speaker) output for audio, NOT my RME FF400 I used without any problems previously. The FF400 works fine with other apps (some like TwistedWave) setup in the program, and others (like Spotify) using system preferences & audio midi setup. How can I set the FF400 to be the sound output device in FCP 10.2? N.B. The FF400 is set as sound output device in both system preferences and audio midi setup.

    From the fcp.co forum. See if this does anything for you.

    I have the solution! Well it at least worked for me. This is the response I got from Apple, Can you please try the following steps towards fixing your audio issue, and report back with your results?
    1. Open the application Audio Midi Setup (located in Applications : Utilities)
    2. Select the Output Tab for the current output device
    3. Select the Configure Speakers option
    4. Select the Multichannel tab
    5. Change the setting to Stereo Now mine was set to stereo but the left channel wasn't showing left. re-clicking on stereo reloaded the settings and after clicking apply it worked. 

  • System Preferences not detecting intel high definition audio

    I have tried researching as much as possible before posting and I just can't find a solution.
    I have a 2.4GHz Intel Core i7 Macbook Pro late 2011 running Mavericks 10.9.4 (13E28) on 8 GB RAM and Intel HD Graphincs 3000 512 MB, and my audio devices are not identified in audio MIDI setup or system preferences. Looking at system information the audio hardware is recognized (but there is no "built-in" beside 'audio' in the navigation pane).
    I've tried reinstalling Mavericks, 10.9.0, 10.9.2, 9.3 and 9.4.
    I've tried installing the combo pack for 10.9.4
    After each install I've reset the PRAM and SMC for each reinstall.
    I know my speakers work because I hear the chime when i start up. My internal microphone and line-in are also part of this problem with the audio devices. They don't show up in sound preferences either. To my knowledge the only issue seems to be with the audio.
    My direct question is: How do i make my system preferences recognize my internal microphone, my internal speakers, and my built-in line?
    I'd appreciate any input, this is my first posting to the community. Thank you all for viewing.

    I looked into the community and saw that someone had the exact same problem. Their solution was to backup valuable data and clean install the operating system. I have followed through on this and have sound =). Just waiting now for my backups to complete.
    I'm being cautious what I put back into the settings because I believe that's where some files my have been corrupted. Not sure. For the most part, thanks for viewing to those who did.

  • HT3625 I don't have a "Use audio for:" menu in my system preferences

    When I go to system preferences and try to follow all of the directions in the article, there isn't any menu or anything that says "Use audio for:" when I'm on the input tab of the sound preferences.  How can I get my MBP use the audio input instead of detecting it as an audio output? 

    malcolm007,
    Here is a pin description of the 4 pin connector, there impedence and shunting that needs to be taken into consideration, not to mention the response curve that this is optomized for,ie:headset mic response. There could be potential damaged cause by incorrect matching and shunting (shorting certain pins to ground) you might consider calling Apple and see what their response is. You can even try experimenting at your own risk, I myself can make no recomendation and would advise against it as you could risk damaging your device. I found no data that would allow an informed decision on my part. The audio quality would most likely be sub par for a music type of application anyways, as it is most likey optomized for the headset mic as prviously mentioned.
    USB interfaces are cheap and most sound good and will definatly provide a safe and flexible way to get in.
    IMHO

  • Audio input volume in System Preferences, but not Mainstage

    Hi,
    I am trying to get Mainstage 2 to work with an audio interface (TASCAM US-122 MKII). I've installed the drivers for the interface, and it shows up on my system both in System Preferences under Audio and in Mainstage. When I go to system preferences -> Audio and play an instrument through the interface, volume registers on the level meter. But if I go to Mainstage and select this interface as my input, I get no volume levels registering at the input.
    I've been trying to get this to work for going on six hours now, googling and installing and restarting to no avail. I have the same problem with Garageband too. Has anyone had this happen to them, that an audio interface seems to be recognized by the operating system but not by Mainstage/Garageband?
    Thanks,
    - Nick

    I can't help, other than to say this happened to me today with the same hardware, only with GarageBand.
    I recorded bass tracks this morning -- no problem. This afternoon, though, every time I plugged in the Tascam GarageBand went silent, even though the system input shows sound coming in.

  • After OS Upgrade, System Preferences won't recognize audio input/output.

    When I got an iPhone, I had to upgrade to OS 10.5.8, as well as upgrade Safari (to 4.0.3) and iTunes (to 9.0.1) for everything to run smoothly, and it does.
    However, since I went though the motions last week with these upgrades, System Preferences or Utilities doesn't want to recognize my audio input/output jacks. It won't recognize when I plug in my stereo or my headphones. I hook up my computer to my stereo all the time to listen to music in the living areas of my apartment, and now I can't because it isn't reading the jack.
    Any suggestions? How can I get the system to fix this problem?

    Check your Audio MIDI Setup settings.

  • My USB Tascam US-200 audio soundcard can't be found in System Preferences, but can be found in application? (Screenshots inside)

    I'm having some issues with my audio since I upgraded to Yosemite 10.10.1.
    This is currently what the sound section in my system preferences shows:
    Before I upgraded to Yosemite 10.10.1, I had an option for "US-200" on the list to select.
    I use music production software Cubase, and that application finds the sound card and allows me to play audio using it (another screen shot below)
    I'm just confused as to how an applicated on my Mac can find it, but it doesn't appear on system preferences? Is there a fix so that I can bring my system preferences to show my soundcard so that I can play music from iTunes through my Tascam US-200?
    Any help would be greatly appreciated
    Thanks

    It complains not just about one class, but about EVERY class that's loaded dynamically. When loading classes dynamically in a built exe, you have to specify their locations inside the build profile. This is what's done under "Destinations." Specifically for classes, they must ALL be either inside or outside the exe.
    Because my application is deployed to end-users, I want the classes opaque to them, so I set the destinations to be within the exe. This works fine, and the exe builds without problems, with all the classes embedded inside.
    The problem is the installer thinks all the classes that have been built into APT.exe are actually located in a system folder called "APT.exe." That's obviously wrong, so when it tries to grab those classes from a nonexistent file location, it returns an error.
    I know I'm not the only one building classes into exes, so I can't be the only one seeing this problem.

  • How to add audio devices under sound in system preferences

    How do I add output audio devices under system preferences --only option listed is internal speakers?
    Macbook help says to change device under sound in system preferences. However, only option listed it the internal
    speaker.
    I need to sound to come from my tv which is hooked via vga cable and audio cable.
    Every thing works but I cannot get sound from tv.

    You are my hero. I'm not very savy when it comes to connections. I had the audio cable hooked up to the audio port which is next to the headphone port on my macbook. After switching the tv was listed just as you said it would. Thanks so much. I'm now a very happy camper.

  • 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.

  • Am trying to record a basic guitar track while I sing along.  I don't want my vocals to be recorded at the same time but the internal mic seems to be picking up the vocal and guitar sounds.  I tried System Preferences, Sound, Line In - Audio Line Input.

    for me it turned out that the jack into the iMac was loose.  Once I fiddled with it everything worked okay

  • Removing audio system preferences?

    I used to have a digidesign audio interface - but changed it. However after removing Pro-Tools/digidesign software from my mac - I still have the mbox audio interface as an option in my imac audio in/out system preferences.
    Is there anyway I can remove this from the audio system preferences somewhere (in user library?) - as it doesn't exist for me now?!

    "Is there not a folder in the system somewhere - that allows me to remove the unwanted audio device from the input/output preferences pane?"
    If the app came with an uninstaller, then it's gone now since you already got rid of it.
    Have you tried my previous suggestion?
    +"Use Spotlight to look for any straggler files. Just type in the name of the app in the search window."+
    You can even delete files directly from Spotlight.
    Or you can manually go into the Preferences Folder to see if you can find any .plist files that has the same and/or similar name as the app you are looking for. Crossing your fingers that the app did not place scragglers in any other place on your system as 3rd party apps sometimes do.

    Good luck!
