• 13 d-0016nl envy: problems with the HDMI audio

  Dear Sirs,

  Due to some problems with an engineering program I had to reinstall Windows 10 on my laptop. The version of Windows is the same of the one installed on the laptop when I bought it. Before the laptop with HDMI audio installation worked fine, but then, while the HDMI video continues to work well, the audio turns off directly from the laptop, such that the cable was not connected.

  I tried to activate the 'reproduction devices' HDMI connection, but I'm not able to do this because it's as if the cable is not connected, and the HDMI connection icon appears as gray.

  I tried to update the audio driver, but it didn't work, so I tried to download and install the latest version of these drivers from the hp site but neither this worked.

  Can you help me? The laptop is quite new and I would like to solve this problem without using 2 different cables to connect also a speaker with a cable to the because the HDMI does not work as it should.

  Thanks in advance,

  Martina.

  You are the very welcome, Martina.

  It would be the graphics driver you need install the HDMI audio driver...

  This package provides the driver that allows graphics Intel high definition (HD) in the notebook models that are running an operating system supported. If the video output high-definition multimedia interface (HDMI) is supported, this package also installs the HDMI Audio Driver.

• I have a problem with the HDMI.

  Original title: HDMI audio problem.

  Hi there;

  Until someone tells you I know it's a common problem but the solutions I've seen did not work at all.
  So I am running Windows 7 Home Premium to my Lenovo Ideapad Z370 and I connected to a few televisions using my HDMI.
  It used to work so that I could connect and the sound and picture will work fine but now audio doesn't work and I don't know why.
  I know that it is not the HDMI cable my Xbox 360 it crosses without problem and is not the TV, that the problem persists with different TV is a setting on my laptop.
  I tried "show disconnected devices" on playback devices. I tried to set the upper and lower frequency protection threshold, but the settings don't do not stay, he says that it is disabled. Nor can I set the device by default because the settings are grayed out, even if I am system administrator. I tried the update and downgrading my driver, deactivation and activation of the HDMI connection and I am now fresh out of ideas or any solution that I can find on the internet.
  I need help please.
  Thank you
  Owen

  Hello

  I understand that when you connect the laptop to TV with HDMI you do not hear the sound on the TV.
  You hear the sound on your laptop?

  Try the following steps to uninstall and reinstall the audio drivers from the manufacturer's Web site.

  (a) click Start, type devmgmt.msc and press ENTER to open the Device Manager.

  (b) expand the node under Audio, right click on the entry of the device and click Uninstall.

  (c) in the dialog box confirm the device removal, click OK to start the uninstall process.

  (d) when the uninstall is complete, the site of the factory driver download and install the drivers.

  When I try to view certain websites, I get an error message that says: "there is a problem with the security of your connection Metwork.

  Hello

  Can help someone, I have a C650 and everytime I try to connect to something to him via the USB ports, it is not "found" by the computer?

  The other night, I tried to get pictures on my phone but it wasn'; work and I put it down to a problem with the phone, but today I tried to install something digital crafts for my daughter and during installation it tells you to insert the thing into the USB port and click Next, when I do that he's going through a lot of "research" and said then it can not be found.

  The laptop makes a beep sound as it would on an extraction device when you plug... I hope that makes sense. So I am now assuming that the problem is with my computer, is there something I can do to fix this?
  Thanks in advance

  Sorry should add - it's like nothing is plugged at all when it is, and it happens on two USB ports, not just one...

  > but today I tried to install something digital crafts for my daughter and during installation it tells you to insert the thing into the USB port and click Next, when I do that he's going through a lot of "research" and said then it can not be found.
  I guess this could be a problem with the software or drivers installed.

  I searched a bit and his city that he has a software is compatible with windows vista/2000/xp. Win 7 is not mentioned do not know if this could be a problem, but in your case, I recommend asking the support of this software product for some advice.

  In addition, you can try to install this software once more, check whether this USB problem appears again.

• Problems with the data connection

  Hello
  I bought a Z3 Compact Xperia on December 10, 2014. I live in Italy and I use Vodafone as my everyday.
  I got a SIM card replacement nano with LtE capabilities just to get the phone in the new fast network. The problem I encounter is that, since on January 13, 2015, I had some problems with the data in mode 3 G connection.
  So far, I used my phone normally, then I tried to send a text message with WhatsApp and phone stuck with the clock icon in the lower corner of the bubble of the message. I thought it was a temporary network problem but I'm not sure about this.
  I live in a small town where the coverage is really good, either in 3G and LTE. I tend to use the 3G because it uses less battery and it does not affect my 4G data plan.
  Th issue, it's that if I do a speedtest when I feel that network glitch I have a ping, but with very good download speeds up to 2000ms.
  The problem is that I believe that this is not a network problem because my mother has a phone HtC One S and runs vodafone without problem even when I'm having the glitch.
  I tried to reset the phone to factory settings, but it did not help.
  In LTE / 4G I do not experience this issue. In fact, I think if there is problem need a phone related software because the antenna works very well.
  If it doesn't I'll try to contact ad Vodsfone then I'll send my phone for the helpdesk if Vodafone tell me that the question is not on their network.

  Thanks in advance for your help.

  It's pretty strange, double check the APN settings and contact EE in this regard.

  Disable the DHCP broadcast flag: link: http://support.microsoft.com/default.aspx/kb/928233

  Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click on the number below to view the article in the Microsoft Knowledge Base:

  http://support.Microsoft.com/kb/322756

  (How to back up and restore the registry in Windows)

  Windows Vista cannot obtain an IP address from certain routers or some non-Microsoft DHCP servers

  To resolve this issue, disable the DHCP BROADCAST flag in Windows Vista. To do this, follow these steps:

  1. Click Start, type regedit in the search box, and then click regedit in the list programs.

  If you are prompted for an administrator password or for confirmation, type your password, or click on continue.

  2. Locate and then click the following registry subkey:

  By setting this registry key to 1, Windows Vista's trying to get an IP address using the BROADCAST flag in DHCP Discover packets. If that fails, he will try to obtain an IP address without using the BROADCAST flag in DHCP Discover packets.

  Hope this information is useful.

  Let me know if it worked.

• When I try to record photoshop mi account, there is a problem with the internet connection and I can't continue. How can I solve it?

  I bought a book on Photoshop CS many years ago, and once I installed it in my computer it says I should I enroll the account in order to use Photoshop (or something similar), and it also has a link to go directly to the website of the registry. The problem comes when I try to access this link given, which is an internet link. It appears that my Internet connection is not secure, so I'm not allowed to continue the process, even if I don't really no problem with the connection. As I'm talking about an older version of Photoshop CD, the problem might be that something related to the incompatibility with my version of microsoft.

• Problems with the socket connection

  Hello

  I am trying to connect to socket between blackberry and pc Simulator, so that blackberry and pc can talk back.

  When the server tries to turn the blackberry, he failed.  (Survey net.rim.device.cldc.io.ippp.SocketBaseIOException: Connection Timed Out)

  And the blackberry cannot send data to the server successfully.

• I have a problem with the internet connection frequently fall.

  A strange thing that baffles me is when I go to one of the houses of my friend, my new laptop has the greatest difficulty using his wifi. My laptop has no problem using someone elses and none of the features of my friend has a problem with its wifi. Even my old laptop has no problem.

  The internet will be always connected while at my friend's House, but he often will not load pages, going very slow if it charge anything and takes some time to re-establish the connection if it does not charge not all web pages. Its wifi is normally quite fast and this are speeds very abnormal and crashes, he's never experienced. Yet once again, only my new laptop knows this. It loses connection with the router, just with the internet. You will see often Skype lose connection and may stay connected for 1 to 10 seconds before it shuts down again.

  have tried to reinstall the wireless drivers but no luck. Reset the driver does nothing. Restarting the laptop does not help. Restart the router does nothing. Removing the router of my set up and you reconnect to it does nothing. Any help with this problem would be highly appreciated!

• Problems with the internet connection Wi - Fi

  I posted a few days ago that I recently switched internet providers, and since my laptop shows or says it is connected but when I click on something, it appears in the taskbar bottom right of the screen there is no internet connection, but still it always shows an internet connection.  I have the laptop configured to use the connection with a router that is installed on my main computer. There are no other problems with any of my other devices, other phones, tablets or smartphones.  It just seems to be this laptop.  Its a Vaio Sony, bought February 2012.  I tried what was suggested last time, go into the control panel and the activation of something.  Im not a tech person, please help.
