I am unable to adjust the Master volume in the Audio MIDI Setup utility.

For either built-in Input or Output. The systems effected are:
MacBook Pro, 13-inch, Mid 2012 (Mac OS X Lion 10.7.4 11E2617).
iMac, 20-inch, Mid 2007 (Mac OS X Lion 10.7.4 11E53).
The volume can otherwise be adjusted via the Sound sytem preferences or the volume control in the Finder's menu bar. I can even adjust the volume for the individual channels for Buil-in Input and Output within Audio MIDI Setup. It is only the Mater volume that can't be adjusted.
Does anyone have any insight as to why this might be? Any assistance would be much appreciated.

I have Iphone4s 16GB, IOS7.0.4 updates having a problem , that when i press + or - volume keys while my iphone is ringing my iphone 4s goes silent .
Whereas you know silent key is used to make the ringing phone silent. This button is working ok while only problem is my iphone goes silent while pressing + or - volume keys as these keys should increase / lower the ringing volume . These keys were ok working in IOS 6.
Where as these keys are also working ok  in music player of iphone for IOS 7, the only problem is for ringing.

  • Why does using a digital connection from headphones out on a Mac into a stereo disable the master volume control on the Mac?

    When you use an analog connector, it does not disable the master volume on the Mac. It's only when you use a digital connector, and it's ALL digital connectors. It still allows you to use the iTunes volume control but, when you stream anything else on the web on your computer, you have to use the stereo's volume control because the master volume control on the Mac has been disabled. Does anyone know why?

    I had the same problem, instead of logging in the router with the iMac (impossible) I did it with my iPad, I guess you can do the same with an iPhone.
    -Disconnect the iPad from your wifi network and connect it to the TP-Link repeater.
    -Open the web browser (I use chrome) be sure you don't have any other open tab, just the one to access tptlinkextender.net
    -The configuring page opens, from there follow the steps of detecting your network and adding the password.
    *If your MAC address is hidden it'll appear without name, in that case you have to configure it manually (write the name on the space for that)
    Now go, be happy and do good.

  • Why I am unable to adjust the ringer volume by the side buttons and there is no ringer with the Mute button OFF

    With the mute switch OFF - I am unable to adjust the ringer volume by the side buttons. 
    When someone calls/texts there is no sound coming from the speaker.
    The headphone jack works when I listen to the Ipod and the speaker works when I change the ringer volume through settings.  So i know that the speaker does work
    Headphone jack seems clean and dust free
    I heard that there may be a Skype issue than can control the speaker volume - so i deleted it but i still cannot get any sound from regular functions.
    When I play the Ipod through the speaker with no headphones there is no option to change the volume and no sound.
    If it works when i go through settings to set my ring volume, my ringtone plays - then why does it not work otherwise?

  • I made a project with multiple tracks and had it all panned and mixed.  Now it's only playing in the right speaker.  Not even regestering a left side in the master volume?  What happened, how can I get both sides back?

    Thank you for that info.
    For video, the codec is MPEG-4 Video (XVID) and for audio it says MPEG Audio Layer 1/2/3 (mpga).
    There are two issues with that file:
    The first is the Xvid CODEC (not meant for editing), and then the MPEG Audio/MPGA. I would convert that file, to something that is more editable.
    Good luck,

  • How does KMDF driver control the master volume of Windows?

    Dear Sirs:
    I am developing a KMDF codec driver. 
    One of features is that the user can press buttons which are attached on a headset to manipulate the render volume.
    Is there any windows API available to allow me to control the master volume of Windows under KMDF developmnet?
    Thanks a lot.
    Sincerely, 
    Zale Yu

    Hi Doron,
    Thank you for pointing out the direction. Here please allow me to ask two questions, and also please review a possible solution.
    Question: 
    - may I ask for more details on how to do this underlying bus driver? i.e. could you kindly list a few steps on how to do this? 
    - Any related samples available in MSDN WDF I can look at to get th idea/even reuse the code? 
    Possibl solution:
    - how about claiming the codec device as a HID devic as well, and make a minidriver to pass through IRPs to filter driver which captures/interprets the button-press interrupt and then send HID report to change system volume? is this feasible?
    any conflict: Can Kernal add th driver (now Codec function Driver, Mini driver and a HID filter driver all together) stack together -- so the right driver can process the packet interested?
    Thanks again.

  • [SOLVED]Alsamixer - the "mute" option for the Master volume is missing

    Hej!
    After the recent update the Mute option is missing for the Master volume but I can mute sound for PCM.

    Okay, can you provide documentation/reference to back that up? Should you mean, there is no difference in how you system behaves, yes, that is very likely, since the second line is correct, so the cmi would be at index 0 either way.
    Andy_Crowd wrote:Mute shows only when I am installing pulseaudio.
    In alsamixer? PA runs on top of alsa, so the controls for alsamixer should stay the same. Do you mean another mixer maybe?
    You still did not provide the relevant part of pacmans log and amixer output for both cards. Are you certain you used the cmi as default the whole time? Is the snd-hda-intel a hdmi sound card?

  • No Volume in system tray, master volume disabled, no audio drivers - Dv6500 model

    Hi,
    OS- win xp sp2(downgrade from vista to xp )
    Model: dv 6500
    I need serious help with my audio drivers. To start off there is no volume icon in my system tray, so I tried to enable it  through control panel but before I try to enable it, the master volume is already greyed out so there is no way i can  enable it or get it on system tray nor can i change the volume, mixer setting  or just any setting in sound volume and devices dialog box.
    Initially in teh properties tab of sound and devices the message was all drivers are working fine however still I could not listen any voice from any application. I tried to reintall the old audio driver(sp34200) and new one's like sp33310 still there is no audio..
    tried to start audio application in services but still no result, did a virus check  but it shown no virus attack. I have given up , plz help me out . I am exhausted i guess I ahve tried each and everything available on net.  plz plz help someone.

    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.

    So in the last few days I’ve noticed that pressing my volume change keys actually isn’t changing the volume on my macbook pro at all. When I press the volume up or down keys, it makes the recognisable pop sound but stays at the same volume while the squares go up or down. I mute it but my computer still makes sound. It’s the same with the volume control up the top of the screen, too. I slide it up and down and it doesn’t change the volume at all. The only way I can change the volume is with my speakers or the program I’m in (iTunes, VLC etc). I restarted and it seems to be okay then I go to change it a couple minutes later and it’s back to not working again.
    I’ve checked my settings- the “use all F1, F2, etc. keys as standard fuction keys” is not switched on, and I have tried a suggestion of moving the com.apple.systempreferences.plist file out of the library and onto the desktop and restarting and neither of those seem to make any difference whatsoever. I’ve tried to find online forums but the only suggestions I found were those two and they didn’t work.
    I’m just annoyed because I usually have the worst luck with technology but my macbook had been going strong and I got it because of the apparent lack of things that could go wrong, but of course even if there is one thing that could go wrong it will happen to me.
    Please help!

    I have lost sound on my iPad in apps unless I use headphones ,does anyone know how to get sound back without them .I have used the mute volume on the bar at bottom of screen and the slider volume control there only shows when headphones are plugged in !
    I also tried resetting settings all to no avail ...I looked up some advice and watched utube video advice on how to fix without success..
    The volume control button on side does not work ,I got the iPad last August and wonder if it is a fault that means I must return it for replacement from where it was purchased ?

    The Retrospect you used way back when is no longer around. The company was sold and that company produced a new version of Retrospect - Retrospect 8.x
    So, as you've been told, you would have to be running a Tiger system with an old version of Retrospect software (5.x or 6.x - you would need to know) assuming you can find the software.
    As best I can remember you cannot extract files from a Retrospect backup except using the software since Retrospect did not normally make a file by file backup rather it created an archive of the files in the backup. I'm assuming that the EMC/Retrospect people have told you that old Retrospect backups are not accessible by Retrospect 8.x?

  • Why Is The Menu On The Master Page BELOW The Objects In Other Pages?

    I added a menu on the master page using the Composition widget called featured news and it stays behind the other objects on normal pages.
    How do I fix this? Here are the pictures of the menu when it's closed and when it's open.

    Make a new layer, which is by default placed above all other layers.
    Go to your master page and drag the menu onto this layer.

        chrisglobe7,
    We want you to be able to enjoy all your music! Were all the songs downloaded from the same source? Are all the songs that play at the low volume from the same place? Is the music you are listening to stored on your device or a 3rd party application?

  • Why can't I reset the master password with the option of removing all username:passwords by unchecking "Use Master Password"?

    Why can't I reset the master password with the option of removing all username:passwords by unchecking "Use Master Password"? Currently, there seems to only be the option to issue a "chrome:" command in URL which DOES reset the master password. However, it was something that I had to google. The intuitive option would be to uncheck the "Use Master Password" checkbox, receive a verification dialogue, and blammo, password reset. Please make this a feature, thank you.

    ''cor-el [[#answer-702776|said]]''
    <blockquote>
    You can remove all password in the Show Passwords dialog.
    That is where you manage the passwords.
    The master password is only for protecting the passwords with an extra level of encryption and has nothing to do with erasing passwords apart from resetting the MP in case you have forgotten the MP and can't open "Show passwords".
    </blockquote>
    Sorry, for being unclear. Essentially this is a feature request for an option under Firefox options (why not?) to reset my Master Password not knowing the Master Password. For Security reasons I understand why all the saved passwords have to be wiped, but wiping the Master Password (having forgotten it) should be an option without having to issue an arcane command that one has to google to figure out.

    Is there an app that can control the ringer volume by the time of day. Like say i had work. Is there an app that can automaticly change the ringer volume on certain days at times you input to lower the ringer volume?

    Can a app like this be made or will apple not allow it?

    Hi OMAW8,
    It would be better if you could share us the detailed error message in English.
    Do you mean that you could run your test in your build agent machine? If so, I doubt that it would be related to the TFS build. I mean that maybe it is not the test issue.
    Please share the detailed error in English, and then post this issue to the TFS-build forum would be better for this issue since it works well in build agent machine.
