Sound doesn't work when I plug in my monitor to HDMI port

I have a new HP Envy15laptop and an older AcerAC2016W with VGA connection. I purchased a vga to hdmi adapte cable. When I plug in my monitor, the sound shuts down. If I unplug the monitor the laptop speakers work fine.

Hi,l I don't know which VGA to HDMI cable you are talking about but VGA does not carry sound and your machine may think it use HDMI sound therefore it shuts down sound with HDMI, if you wish to use sound from your computer you need to disable HDMI sound: Right click speakers icon > Select Play back devicesSelect use internal sound and disable HDMI sound (if it was there) You have to enable it when use pure HDMI (ie from HDMI to HDMI TV for example) Regards.

Can I use Factory re-set to fix that ? My Screen doesn't work when I put on mini display to HDMI My TV then set Mirror Main Screen.

Last week I bought a miniDisplay to HDMI port. My macbookpro to SonyPlaystation 3D TV , it's work petty well on default setting. But when I set to Mirror setting, macbookpro screen turn to blue(more like computer is setting) then turn to normal and 1 second later turn to blue......that's a loop...never stop. only when I took out the miniDisplay to HDMI port, that stop...The TV doesn't have signal.
I tried to delete apple.display.config files, but I can't find all of them( I already followed Apple support page article), so this way still doesn't work for me.
what way can help me fix that?

Disconnect the external monitor and any other third-party peripherals. Be sure to backup your files.
Clean Install of Snow Leopard
     1. Boot the computer using the Snow Leopard Installer Disc. Insert the disc into the
         optical drive and restart the computer. After the chime press and hold down the
         "C" key. Release the key when you see a small spinning gear appear below the
         dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, set the format type to Mac
         OS Extended (Journaled, if supported), then click on the Partition button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.

X220i: sound doesn't work when camera is activated

Hi all,
I've a weird problem: my sound works well when I'm listening music, video, etc. whith the speakers or an headphone.
But when I activate the camera (for Skype or Google Hangout), the sound stops to work (while the video image works well).
When I try to manage the sound (by making the sound test during a videoconference), I got this error message (sorry, it's in French, it means "Impossible to read the test tone"):
Do you have any idea where the problem comes from?
Thanks in advance.

Hi, djiwai91
If you haven't already, I would recommend trying to update all your drivers and your BIOS to see if that helps. All updates for your system can be found here. After downloading and installing them, test the camera again and see if there are any changes.
Best of luck,
Adam

Sound doesn't work when two user accounts open?

I noticed that when I have 2 different user accounts open, the sound only works in one of them. Why is this?

The iMac is only designed to have one active user at a time, so there's sound only for the account in use.
Hope this helps

Sound doesn't work when app is reactivated

Hi,
I've developed a small game and deployed it with the packager for iPhone.
Everything works fine until a call interrupts the game. I listen for the events with:
// a call interrupts the app
ativeApplication.nativeApplication.addEventListener(Event.DEACTIVATE, onDeactivate);
// the app is reactivated after the call is finished
NativeApplication.nativeApplication.addEventListener(Event.ACTIVATE, onActivate);
When returning to the app everything works fine except the sound effects are not working anymore.
It seems as if iOS »mutes« the app for the call but forgets to »unmute« it when returning.
Anyone experienced the same? Any solutions to this problem?
I appreciate your help.
Cheers,
Fabian

i'm not so sure it's an iOS problem. i suspect a coding problem.
to test, create a new app that contains one frame, your sound in the library with a class (eg, S) and add:
var sp:Sprite=new Sprite();
addChild(sp);
with(sp.graphics){
beginFill(0xaa0000);
drawRect(10,10,20,20);
endFill();
var s:S=new S();
sp.addEventListener(MouseEvent.CLICK,f);
function f(e:Event):void{
s.play();
make sure the sound plays when the sprite is clicked, receive a call and then re-activate your app. if you fail to hear the sound with that code, try:
var sp:Sprite=new Sprite();
addChild(sp);
with(sp.graphics){
beginFill(0xaa0000);
drawRect(10,10,20,20);
endFill();
var s:S=new S();
var sc:SoundChannel;
sp.addEventListener(MouseEvent.CLICK,f);
function f(e:Event):void{
sc=s.play();
var st:SoundTransform=sc.soundTransform;
st.volume=1;
sc.soundTransform=st;

Ethernet doesn´t work when i plug in the cable.

The network-panel says "not connected". How can I activate the port? or get my ethernet to work?

Try restarting the Mac with the ethernet cable plugged in and with a live device attached ('live device' = another Mac, a modem, a printer, or a hub/switch/router, which has been powered on).

My ipad 2s sound is not working when I have headphones in.

I've had the Ipad 2 for about two years now and my sound doesn't work when I have headphones in. I mean it works but I have to turn the sound up all the way and it sounds like it would be on the lowest sound mark. Is that confusing. I thought it was my headphones at first and it didn't really bother me because I didn't use headphones a lot. I had the same headphone for about a year which is why I thought they were the problem, but a couple of months ago I got some new, really good pair of headphones and they have the same problem. If I am watching youtube without my headphones and I turn it up all the way I can still hear it if I walk upstairs, but if I put headphones in and turn it up all the way I can barely hear the sound. I know it is not the headphones because they work perfectly in my phone. Is it something wrong with the headphone jack and can I get it fixed at apple.

Reset iPad
Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears

Macbook pro buzzing, sound doesn't work, disk is falsely full...

My 15 inch macbook pro has started buzzing a lot lately at random times. I've had it since 2009, but it's a 2008 model, and I don't know if it's just getting old and telling me that it's going to die soon, or if there's something I can do about it.
It also has other problems, like the sound doesn't work when I start it up (the volume icon is greyed out), and doesn't work again until I've restarted it twice.
Also, when I have programs open, it'll tell me that my disk is full and I only have a few mb of disk space left even if I had many GB available before I opened the programs. I tried fixing this on my own by not having multiple programs open at once, but the disk space won't come back until I restart the computer. It only started doing this a few months ago, and I don't know why.
I used to keep it on all the time and just let it sleep, but I've been shutting it down every day now, and I have the same problems. I don't know what's happening, if it's my fault, or if my computer is just dying, but I need it for animation school and professional photography so if possible I want a heads up if it's about to crash on me.
Thank you.

This worked for me
Reboot the Mac and as soon as you hear the boot chime, hold down the Command+Option+P+R keys together
When you hear the boot sound again, the PRAM has been reset so let the Mac boot again as usual
At this point your Mac should boot again as usual and no longer have the black display, loading OS X as usual.

MP3+ USB External Card doesn't work when plugged into USB

My MP3+ USB external sound card doenst' work whenever I plug it into my usb hub.
Model: sb0270
First I tried a powered D-link 7 port usb 2.0 hub. (model DUB-H7, H/W ver: 2) although the model number doens't tell you much is has the same model number as a USB/Firewire hub with 3/4 ports.
The sound card is recognized as a "composite" device. But no sound goes "through" it (light doesn't flash).
I'm now using a Belkin 7 port usb 2.0 hub, model f5u237 rev. 3.
When I plug the soundcard into my computer it stops the laptop speakers, and then my sound system starts playing. When I unplug it my sound system stops, and then my laptopspears start playing. When I plug it into the USB hub the sound on my laptop speakers stops, windows finds a USB composite device, then the sound starts playing on my laptop speakers again.
I've tried this on 2 computers a HP ZV600 and a HP dv5040us.
dv5040us specs: http://h0025.www.hp.com/ewfrf/wc/genericDocument?cc=us&docname=c00584686&lc=en&jump id=reg_R002_USEN
This is the only USB device I have that is not functioning correctly. (2 HDDs, keyboard, mouse, printer, mp3 player, controller, and joystick)
Even if those arn't plugged it it still doens't work.

I tried with another USB flash card and with a smaller file.
The transferring from Mac to the card starts but is extremely slow ( around 0,5MB/sec)

In my wife's window, the sound works, when I switch over to my window the sound doesn't work. I noticed the problem when I went to a YouTube video. How do I correct this?

Hello Kiira Doon,
The troubleshooting steps detailed below may help get your iPhone's display to function.
Toggle the ringer switch to see if the unit vibrates. If it does, it could be that iPhone is getting power, but is not displaying any image.
Try turning iPhone off and then on again.
While connected to the iPhone charger, try to reset the iPhone.
If the low-battery screen appears, charge the iPhone.
My issue is still not resolved. What do I do next?Contact Apple Support.
