off volume control

Hello

My Macbook Pro:

When I start my Macbook Pro, I can hear the volume of the speakers to boot.

After the start of the Mac, the volume control is completely disabled and cannot be controlled. But when I plug my headphones his license.

Is there a setting I'm missing here?

Thank you.

  • IOS App Remote - Volume control issues

    OK, so I downloaded the app recently released for Apple TV IOS. Everything works as expected, except the inconsistent Volume control.

    I have two Vizio TVs in my house - E701i-A3 and models M401i-A3. The volume via IOS app works perfectly on my E701i-A3 - pressing iPhone volume buttons triggers change in volume on the soundbar attached to this set.

    No luck with my M401i-A3 not set - by pressing the volume iPhone buttons does cause changes in local ringtone volume iPhone... that tells me something is not right with audio control EAC between ATV4 and the TV set. I do not use soundbar with this set - internal speakers only.

    Both sets are running the latest firmware of Vizio and CEC/audio is enabled. No problem to control the volume or turn the sets/turn off via the remote Siri material.

    Kind of ideas here... anyone have any ideas as to what the problem may be with my Vizio M401i-A3 defined? Someone at - it got IOS volume remote control works with other models of TV?

    Volume control requires HDM - CEC to ensure compatibility. It is quite possible that only one of your TV is compatible.

  • Tecra M1 high slope Screech of volume control

    Hello:

    For a little while that now there was a sharp cry when the volume was turned up. He started at the upper end of the volume and systematically, it started when you only carefully increase the volume. Now the volume control should stay off.

    There is no interference when connected and it also happens when the computer is in stand-alone mode when they travel.

    Tecra M1 is now 18 months old and, also, the modem does not work with any sound by modem and the Port remains closed. It is now, when you are far away DSL, using a portable modem if wifi is not available.

    TIA.

    Martin

    [Edited by: admin]

    Hello

    In my opinion, you must change the speaker volume in the properties of the Modem software. As far as I know the settings should be set to the second stage.
    You can find it in: Device Manager-> Modem-> Modem Properties
    Second if you want to use the Modem must be disabled the option wait for the dial tone before dialing.

  • Wave volume control keeps resetting to level lowest

    Volume slider control wave reset automatically level the lowest volume.  Sometimes the cursor moves down, resulting no sound, sometimes the cursor remains stationary with no sound.  Still, I can click on the cursor and its takes a few moments and then turns off.  I checked my drivers and they are the most current available.  I am running Windows XP with SP 3.  Suggestions are appreciated.  Thank you.

    I'm also facing this problem.  It is events actually very predictable.  It occurs approximately every 90 seconds.  VERY... WEIRD!

    Through the "Process Monitor" sysinternals.com program, I traced the culprit to svchost.exe.  When this happens I see a 'RegSetValue"and is defined as follows:

    HKLM\System\CurrentControlSet\Control\DeviceClasses\{6994AD04-93EF-11D0-A3CC-00A0C9223196}\##?#HDAUDIO#FUNC_01&VEN_111D&DEV_76D5&SUBSYS_1028040B&REV_1001#4&160BAD3A&0&0001#{6994ad04-93ef-11d0-a3cc-00a0c9223196}\#RearWave\Device Parameters\Mixer\ 2\Controls\ 0\Channel 0

    Type: REG_DWORD, length: 4, given: 0

    (I guess "Channel 0" and "Channel 1" is ' left' / 'Right' respectively "").

    If I change with Volume control program, 'data' that gets value are a value non-zero.  (Volume min = 0; Volume max = 65536)

    When I check the 'stack' for this event, I see the following.  (This has been exported in a CSV file.  Should be visible in MS Excel):

  • monitor volume control charts

    Hi, I'm new here and hoping to get help with a problem to upgrade for my.

    HP Pavilion laptop dv61210sa.

    Original OS is Vista Home premium. All freshly installed wins 7 32-bit and updated all the drivers

    for hardware & software but have a minor problem. Not important but irritating.

    The Group of media (bezel) above the keyboard has a touch volume control / pause buttons

    [with lamps]. The volume control works & button mute but NOT on screen graphics that worked well with Vista.

    Features include a lamp of block numbers that works OK.

    The Internet button on / off that turns Orange / Off - Blue when on that will not function now and is

    orange & non-functional permantly.

    Please can someone tell me if it is a software problem or graphic material associated with 7 wins as a whole, it was

    fully functional with Vista Home premium 32-bit.

    Thank you very much for your support.  S John

    and the function of the button. I have information on the new motherboard, the make and model, so hoping to get help

    For anyone who plans to update in win 7 or 8, I recommend to perform the upgrade process.

    I found it slow, but very successful without much trouble trying to find all the updated drivers etc necessary.

    upgrade. I just wish I made it to begin and has saved me a lot of time and bother.

    Well, I'm a boy in my 50 and still learn to face technology haaaaaaa

    Thanks a lot for your help / concern. I hope that this episode will help all those who want to upgrade to

  • Grey ringer volume control

    I have a Z3 Compact with Android 5.1.1. The problem is that I can not change the ring volume. I don't have any other sound problems. As you can see from the screenshot, the ringtone volume control is grayed out. Any idea what could be the problem?

    You may need to perform a repair of software using PC Companion. The process will erase all internal memory. You might need to charge your device for about 1 to 2 hours until the device has so at least 80% battery.

    Make sure that the device is not connected to the computer or laptop and turned off (sometimes you have to press the power button / stop and volume until what the machine vibrates 3 times or on some devices, it must push the small button near the tray on the back of the camera or SIM).

    Open PC companion-> support area-> update phone software / Tablet-> repair my phone/Tablet blue highlighted. Follow the steps, do not plug your phone until you are prompted to press volume down while plugging in the USB cable. If PC companion does not start the repair process, you may need to run Windows 7 compatibility mode (in some cases XP).

    How can I make Blender see other sound control applications users

    Hello gmayes,

    In addition to what Anthony has provided above the quick change of user in Windows Vista is designed to run programs that are specific to each user profile. This means that when you play the music in a single profile and use the fast user switching will continue to play music and the secondary profile will not have access to control the Web pages or the volume of the music played on the primary profile.

    Using programs of another quick switch mode user profile is not something that is supported by Vista right now.
