Taken helmet Mac Mini internal hum but works fine

My Mac Mini made headphones humming internal but works very well. The hum is not constant. When I boot it is quiet so if I play a sound in ANY format or any program that there is a strong buzz that starts and the kind of "" did ramp up the tone. If I stop then the sound of the source of the hum lasts almost exactly: 30secs and then all stops. Again, it is only through the headphone jack, the Interior is fine and works as usual.

I had plugged in a new audio line just before it happened... I wonder about a failure/problem of grounding. I have also used an IO just before Scarlett and the audio output. It is no longer connected.

I have "waved it a little" cleaned, tried headphones and speakers, disconnect the power source and replaced by another source and of course turned on again with and without the connected headphones.

It is a Mac Mini from 2012.

Thanks for any help.

Could be a ground loop in your power connections. Try unplugging all unnecessary devices in power and to change the socket where the Mac is connected

  • JavaScript does not in FF, but works fine in IE, Chrome, Opera, and Mobile devices

    On this page, the menus javascript (two of them) often do not load. If I click on Ctrl + F5, they can load on the 2nd attempt. This Page works fine in IE, Chrome, Opera and mobile browsers, but not in FF. I cleared FF cache by going to options and have also worked with modules and plug-ins to 'ask to activate '. This problem persists...

    Javascript menu bars sometimes don't show at all, or sometimes will appear, but have empty menu items (menu options do not show).

    http://www.consultapedia.com/international/international_marketing/intl_mrktg_skill101.htm

    I've included a screenshot of how they (don't) appear in FF. Also another screenshot of how they appear in other browsers, or when I click Ctrl + F5 in FF.

    Hmm, there is a lot of content added by scripts on this page after a delay.

    Firefox has several optimizations to speed up the display of pages in the cache which may malfunction under certain circumstances. For example, display a page using the Back button will not necessarily trigger an "onload" event in the page. This article describes how to work around this problem for web developers: https://developer.mozilla.org/Firefox/Releases/1.5/Using_Firefox_1.5_caching

    For end users, it is a difficult problem to solve. A partial solution might be the following:

    (1) in a new tab, type or paste Subject: config in the address bar and press return / enter. Click on the button promising to be careful.

    (2) in the search above the list box, type or paste sess and make a pause so that the list is filtered

    (3) double-click the preference browser.sessionhistory.max_total_viewers and change the value from-1 to 0 (that's a zero).

    (Please change not all other parameters similar to 0-sounding or you can disable the ability of Firefox to save/restore your tabs and windows open).

    Then reload the page problem and trying sail away and back to see if the inserted content is preserved.

    There may be a performance penalty slight for this change, but you probably won't notice it. Firefox will be used in the file cache, it will just go up the page in a slightly different way that often works around this issue.

    Does make a difference to you on this site?

  • the videos do not work in Firefox, but work fine in windows Explorer. Why?

    I tried to check my plugin and all are enabled. I found here where it was suggested to delete and reinstall Firefox, but that did not fix problem either. I tried to change the Viewer for video, but still no luck. Not sure why Quicktime does not work. Note that when browsing videos will not open, but everything else works fine. Videos work very well with windows explore, but not Firefox.

    Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/tools > Modules > appearance).

    • Do NOT click on the reset button on the startup window Mode safe or make changes.

  • YouTube freezes or crashes firefox but works fine in Internet Explorer

    Every time shoot youtube in Firefox it immediately freezes or crashes with the whole browser. the only thing I can do is close Firefox via the Task Manager. This happens every time. It used to work fine. I have disable even speed up the video. Nothing seems to work. The only time where this kind of work is when I uninstall and reinstall firefox or flash player. Then the first time I have pull up to youtube, it works fine but when I close the browser, then re-open it and go on youtube, I have exact the same problem as before.

    Firefox will pull up to youtube without problem when I uninstall the Flash Player (of course can not see the videos then), but after the installation of youtube freezes.

    Also Internet Explorer out of the youtube videos great, like Firefox, used to do. Don't know what the problem is or what has happened, but youtube immediately freezes or crashes Firefox when Flash Player is installed in firefox

    Hey guys I think we have a solution for this one. More often the case, the glitch is not with FF but with some plugin or incompatible piece of SW.

    Troubleshooting: Uninstall FF, uninstall flashplayer, uninstall all toolbars in the browser add ons etc. (if necessary, use Adobe Flash uninstaller (http://kb2.adobe.com/cps/141/tn_14157.html#main_Download_the_Adobe_Flash_Player_uninstaller)

    Reinstall the latest FF and latest Flash Player version.

    DO NOT add, activate, fix anything else at all. Just naked FF and only most recent flash player.

    If you had Zone Alarm toolbar add the earlier and have uninstalled and reinstalled do not, FF is likely to pullup videos youtube without problem.

    Zone alarm toolbar is incompatible with FF when installing Flash Player and pulling upward on a youtube page.

    It is likely that other toolbars can also be incompatible so just install the naked browser and then the Flashplayer. If it works you can begin to reinstall addons etc one by one.

    Hi Sean,.
     
    Check if any firmware or the last update is available for the device from the manufacturer's website.
     
     
    You can also run the troubleshooter from the link given below and check if that helps fix the problem:

  • My microphone does not work in windows 8, but worked fine on windows 7

    The microphone on my laptop ASUS A55D does not work in Skype or in the Control Panel, when I select the option "listen to this device. It worked fine in any application earlier on windows 7 and I never needed to check if it is configured properly, nor did I have to install any kind of drivers to make it work.

    Help, please. A response would be appreciated.

    Check the site of Asus for Windows 8 audio drivers * for your laptop. I can see books similar to the A55D model, but not this exact model number. If you follow the advice of close the download link (I'm looking at that says uninstall the old audio drivers before installing new) download and install the drivers.

    Please see:

    http://support.asus.com/download/options.aspx?SLanguage=en .

    Alternatively, you can directly ask Asus for advice:

    http://vip.asus.com/VIP2/Services/TechQuery?lang=en-us .

    * Make sure that you choose the drivers 32 or 64-bit according to your version of Windows 8. To find out if you are running Windows 32 or 64 bits 8, press The Windows Logo key + X on your keyboard, and then select System. Now look where it says, "System Type".

  • Embedded audio player doesn't work with Firefox in a laptop computer, but works fine on a PC. How can I fix? It started with the new design of Firefox.

    This problem apparently only occurs with the audio player built into http://www.theskepticsguide.org/ . I tried other embedded audio players from other websites and they work fine. In the Firefox installed in my laptop, no matter what I do it does not play the SGU podcast. When I try to click on the download option it says "Video cannot be read because the file is corrupted. However, I can play and download the podcast without any problem with Firefox installed in my PC, which is the exact same version that is in my laptop, so I don't really know what could be the cause.

    I remember that this was not the case before the new design of Firefox. I tried the solutions proposed on this problem before asking this question. I checked that the plugins are up-to-date. I removed all the addons and plugins, and this did not help either. Firefox reset with no luck. Also tried a fresh install of Firefox and it didn't work. I used the laptop without synchronization first, and then synchronize with no difference. Flash is up to date and there is no apparent problems there.

    Maybe it's a codec missing or damaged? I wouldn't trust codecs from sources other than Microsoft for this purpose, since Firefox tries to use Windows to read the file.

    If you decide to give up and around the native player for a plugin, these changes of settings usually work for this:

    (1) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.

    (2) in the filter box, type or paste media and make a pause so that the list is filtered

    (3) [except XP], double-click on media.windows - media - foundation.enabled to change its value from true to false.

    (4) double click on media.directshow.enabled to change its value from true to false.

  • Printer will not work on Windows Vista laptop, but works fine on XP

    Original title: printing problems

    I installed a printer on my laptop which runs windows vista. The printer worked fine on another computer that worked on windows XP.

    Is there a compatibility issue with this printer? The printer is an Epson Stylus R200 Photo. Been to the web site of windows and it doesn't seem to be on their list. The R280 is however. Could there be an update or a hotfix for this problem or is it a case of the most recent purchase of a printer?

  • HP 3510 only prints blank pages of the i - pad, but works fine with xp configured portable computer. Why? Help!

    I have a hp3510 wireless printer which worked well with my i - pad and on my laptop when 1st installed.  now it will only print blank with the i - pad pages, even if it still works fine when using my laptop configured xp.  can someone tell me how to fix the problem of the i - pad, so that I can print wireless using this device?

    Thank you!

    I begin with the tension of the Apple device, make sure that you hold the power button down and drag the bar on the screen on 'Off '. If you have more than 1 iOS device that you use with the current of the printer (like an iPad or iPhone) them down at the same time. Then reactivate them all and try to print to the printer.

    If still a problem, I would then turn off the printer, router and device from Apple.
    1. unplug the router, (most do not have a power button)
    2. turn off printer and Apple device
    3 wait about 20-30 seconds
    4 plug router back in and wait for it to be fully operational and all the light on it again as they were before unplugging.
    5 printer and apple pyromecanismes turn on (check the settings of the iPad to make sure he's still on the same network as the printer and "ask to join other networks" is enabled).
