Sound input problem

I have a weird problem: in using a headset to make calls using Skype or iChat I cannot get the headset microphone to work, though the earphones work fine. Everything is plugged in correctly. Have selected the Line-In option in the Sound panel of System Preferences, but the Input Level indicator shows no sign of life. Have selected the same option in Skype. Have also tried a 2nd headset, with the same result. For reference the built-in microphone works fine.
We have 2 iMacs here displaying the same symptoms; what's happening? The headset worked just fine prior to upgrading to OS 10.6.6; is there a link here?

Having banged head against wall for too long I finally took my computer to Apple, where it was determined that there’s nothing wrong with the microphone port; however, the Radioshack headset does NOT work with the sound input device set to Line-in; input device MUST be set to internal microphone, after which the headset microphone AND the internal microphone will BOTH pick up sound simultaneously. Go figure.
May have something to do with the audio-in port requiring an externally powered microphone as per users manual. From MacWorld: If you have experience with multimedia headsets and the Mac, you know that Apple equips Macs with a line-level audio-input jack—one that doesn’t work with microphone-level audio sources without amplification.

  • 975x Sound Input problems

    I recently build a new computer using the MSI 975x mobo.  The only problem is, I seem to have some issues reguarding sound input.
    All the sound features seem to be working except for sound input.  In Sounds and Audio Devices, I have full access to sound output and all the different volume controls and advanced features.  All is well here.  But when I change it to sound input I run into my problem.  In the Master Volume Control on Input all volume controls except Master are greyed out to me and can not be changed.
    In properties, the advanced button for input (where you can find the useful feature of mic boost) is also greyed out.
    I am running the bios off the CD and the latest sound drivers.  Is this a known issue and does it have a fix?

    Are you wanting Sound Capture via CD/DVD or Mic? Are you running 6.1 or 8.1 Speaker setup?

  • Sound Input Problems Using iChat..Inadvertent Loss of Microphone?

    My father-in-law just bought a new 17 inch iMac with an Intel dual core, whole ten yards. Great machine. However, when using iChat with his family he's noticed the the sound input goes dead and then he's constantly searching around with on screen controls to get it back again. I thought it might have something to do with his mighty mouse being that you can sync applications with it. I've walked him through the system preferences to get the sound back, but its seems to be a niggling weird type of issue. Any suggestions?
    iMac G4 Flat Screen   Mac OS X (10.4.1)  

    Hi Phillip,
    Selelcting mute is normally a mouse and click item or from the Video menu of iChat (It does not seem to have a keyboard short cut).
    The Mighty Mouse does seem to be the bset place to look.

  • Sound input problem with Skype earbud

    Just trying out Skype, and using a wired earbud I got free. The earbud is Skype branded, and has 2 minijacks - one is headphone and one is microphone.
    When it's plugged in, if I go into Sound preferences there is no input if I choose Line In (rather than built in microphone). I have made sure the input level is turned up.
    Any ideas? I will check if the earbud works with any other devices, as I suspect they're quite cheaply produced!
    Update: just checked another headset that's the same and it doesn't work either. Neither work with our iMac. It's interesting that they seem to be incompatible.

    Did you get this problem resolved?
    I am having the same problem: unable to input sound....

  • Sound Input problem (external microphone)

    Hi.  My external mike (Samson C01U, USB connection) isn't working; there's no input sound coming through. 
    I'm certain it's not a hardware problem with the mike. 
    On preferences > sound, there's no sign of any input (with input volume level turned right up).  Trying to record on Camtasia / Audacity / Quicktime also isn't giving any input.
    Any suggestions?
    Thank you so much

    Did you try to reboot? Smc reset?

  • Sound input problems - No sound

    My wife and I bought two Macbooks last week and we installed Skype. We tried it for the first time today, she could hear me but I couldn't hear her. The Skype audio settings were fine, as were the sound settings under System Preferences.
    However, although internal microphone was selected as the input device, the input level bar doesn't move at all, therefore isn't picking up any sound.
    Any ideas? Is it likely to be a hardware fault that means returning the Macbook?

    The input level bar you're referring to, is it the one in Sound in System Preferences? If it's not picking up there, you probably won't get it to pick up in any other OSX program.
    It's possible that your sound preferences are corrupt. Try deleting this file & emptying the trash.
    /Home/Library/Preferences/com.apple.systempreferences.plist (Create a backup if you wish.)
    Unfortunately the sound settings resides in a file that controls many other settings like energy management, so you'll have to reconfigure some things when you're done.

    Insert Micropone or any jack in Micropone Input or Aux Input, on your sound card or motherboard !
    AND NOW YOU CAN USE PREMIERE PRO 2.0

  • PLEASE can a AE from NI take a look at my problem. Sound input read behave in strange manner then the buffer size is larger than 2X number of samples to read.

    On my computer I have discovered some strange behavior then reading data from the sound card. Then the buffer size is 2x samples to read everything is as expected. But since I read the sound card 10 times pr second I feel a .2 second buffer is to small. I am using XP, and XP is not a RTOS so with a buffer set to 0.2 seconds I may lose data. Therefore I set the buffer size (number samples/ch on Sound Input Configure.vi) to be in range of 2 seconds. The result then is that then reading from Sound input.vi, a reading often take more than 0.1 second. On my computer it is often 500mSec. Then the next 5 read follows with almost zero interval. I do not loose data. But on my front panel the graphs looks like an very early silent movie. This error was introduced in Labview 8.x. To be honest I think the labview 7.x sound system was much better in many ways.
    But before I point any finger NI. Other people has to verify the behavior I experience. I have made an example showing this error. It is a modified version  of the "Continuous Sound Input.vi" example. Then the "buffer in seconds" control is set to 0.2 every thing works OK. Changer this to a larger number will produce the mentioned above hiccup. The larger number in this control the larger hiccup. Is it any way to fix this? My solution up to now has to use a free 3. part software(http://www.zeitnitz.de/Christian/index.php?sel=wav​eio) But I guess it soon will be outdated. It may not work with newer windows versions.
    Any help at all will be appreciated 
    And yes I have the most updated version fo DirectX. Also I se this in Labview 2009 which I have trail version of. The VI I have made is in 8.6

    If you take a moving average of the 0.2s buffer vs. 3s buffer at an update rate of 10, then they are the same (just under 100ms), so the average refresh rate is the same. I agree that is odd behaviour that the time between sound reads go to zero quite a lot then take a long time once in a while (presumably to fill the buffer
    I guess it goes to zero because it is reading data from the buffer it do not has to wait for data from the sound card. The mysterious thing is the periodic delay. You are also correct then saying that average timing is correct. And in my application I have no data loss.
    If you search for sound in this forum you will find out that many people has reported trouble with the sound system.

  • System Preferences Sound Input is stuck at Soundflower (64ch). I can't change it!

    So, I have a mid-2010 MacBook Pro running OS X Yosemite (latest version). (250GB HDD, 4GB RAM, 2.4 GHz)
    I wanted to record some commentary for my video and to use the mic I went into System Preferences > Sound > Sound Input.
    With my mic connected, I tried all of the 4 options (picture below), but then after closing and opening System Preferences again, the sound input is stuck on "Soundflower 64ch).
    When I try to change it (e.g. Built-In), it "crashes", but not really: It selects the option I clicked for a second or two, then the list disappears and says "No Input Devices" briefly, then the list reappears with "Soundflower 64ch" selected.
    Please help, I've tried some solutions I found online, like restarting the laptop, repairing disk permissions, even a code for Terminal.
    Thanks to anybody in advance.
    UPDATE: ****, I think my Mac is possessed or something. It shows the ring of death when my mouse is on the System Preferences window, and when I try to take a screenshot of the list itself, it lags and doesn't let me take it until "No input devices found" appears.

    Either remove "Soundflower" or refer to its developer for support.
    Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
    Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
    I never install system modifications myself, and except as stated in this comment, I don't know how to uninstall them. You'll have to do your own research to find that information.
    Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button. The uninstaller might also be accessed by clicking the Customize button, if there is one.
    Back up all data before making any changes.
    You will generally have to restart the computer in order to complete an uninstallation. Until you do that, there may be no effect, or unpredictable effects.
    If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
    Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software.

  • 50L7300UC - sound input from Mac not outputting to ARC

    I'm having an odd problem with audio on my 50L7300UC (Canadian model of the 50L7300U). I have a soundbar hooked up via HDMI ARC, and it works fine for audio from my cable PVR, from online sevices such as Netflix accessed through the TV itself, and from my PC (a Windows 8 tablet connected via a mini-Displayport to HDMI cable, which provides both audio and video). But with my wife's Macbook Air, using the same mini-Displayport to HDMI cable, video is fine but the sound won't output to the soundbar. Oddly, the sound does work if played through the TV speakers, but if I switch sound output to the soundbar (which the TV sees as "Amplifier"), nothing comes out. I've tried different settings on the Macbook's audio output (using the Midi Audio utility), but that doesn't seem to matter. Any ideas?

    Hmm, if it doesn't see the internal microphone when connected via the FW cable, maybe you might have to run audio cables from the camcorder line output to the sound input on the Mac.

  • Sound input read multiple soundcards

    Heey everybody,
    I have a problem. I want to read two different signals at the same time from 2 different soundcards. 1 internal soundcard from my laptop, and 1 usb soundcard. 
    So i used the Acquire Sound VI.
    Reading both signals at the same time is not a problem until i set the measuring time to about more that 30 seconds. It gets a buffer overflow.
    So i tried to do the following:
    I first made this with 1 signal first, and it worked perfectly, every second it got updated.
    But, when i added the second signal it only wanted to read the first second of the first signal and then it got stuck, and i had to stop the software by closing it. And then killing labview with the taskmanagement thingey from windows.
    Anyone have any idea what the problem is?
    Greetings,
    Jory 
    Solved!
    Go to Solution.

    Ok, never mind, i've solved it. I made the buffers larger (at the sound input configure block) and now it works like a charm

  • Alternative sound input

    So for christmas, i recieved a wonderful condenser microphone and a preamp. Wanting to make some recordings with garageband, I plugged it all into the 3.5mm jack that was not the headphone jack, assuming that it's the microphone/input... I do not think it is, because nothing will pick it up. I went to system preferences, changed the sound input to the input jack, and the tests did not pick anything up. i tried a regular headset microphone instead, to try to figure out if it was my mic setup or the computer. Sure enough, it's the computer. Both of my microphones work on other devices. is the jack with the diagram that looks like this: >o< the input jack or not? if it is, then why is it not working? if not, then why the **** doesn't apple have an input jack when they have Garageband, a program made for recording?

    Welcome to the Apple Discussions!
    Since folks have been using GarageBand for a number of years successfully with their mics and instruments, perhaps it is the operator...
    The Macintosh requires a line level audio signal to record. So if your kit is not producing line level audio, the Mac will not be able to "hear" it. Most PC mics and headset mics do not produce line level audio and are useless for a Mac without some sort of amplification. Additionally, you will not hear anything from the input jack unless one of two things occurs, the app you are using, such as GB, allows monitoring of the input audio, or you use a freebie app called Linein, from Rogue Ameoba, which enables soft playthrough of inputted audio.
    But if your kit is producing line level input, perhaps you have not configured GB correctly for recording. In the GB Help menu you will see access to a getting started with GB pdf. In Chapter 5 it explains how to configure GB for voice recording.
    Let us know if nothing I have pointed to solves the problem.

  • Sound Input Read VI hangs

    I'm using the SI Read VI to sample from the Soundblaster card in my Dell PC. I've configured the device for 16-bit mono input, sample rate 44.1 kHz, and the buffer size is 1024 samples. The SI Read VI is in a Timed Loop whose period I've set to 23 ms (1024 / 44.1kHz). Following each acquisition, I do some filtering, frequency analysis, and plotting inside the loop.
    The acquisition works well for the first 10 minutes or so that it is running. But sometime after about 10 or 15 minutes, the VI hangs. I've traced the hang back to the SI Read VI, but have not yet figured out how to avoid the hang or recover from it (I have to abort and restart the program).
    Has anyone had similar problems with the SI Read VI? Could there be a problem with the DLL that the SI Read VI calls? Are there any upgrades or fixes for this? Can someone suggest a way to recover from the hang?
    Thanks for any help,
    Mark
