No sound from HDMI (image works fine)

HP Pavilion dv6870us

Windows vista 32-bit

GeForce 8400M GS

No sound via HDMI

Recently, I cannot sound if the laptop is connected to the HDMI to my amp (it used to work before).

In my "manage audio devices" I have only the speakers / headphones / SPDIF

There used to work when SPDIF is connected, but all of a sudden its no longer works

I tried to remove the "Conexant high definition SmartAudio 221" and re - install the new version, but it does not work.

Can someone help me?

  • No sound on HDMI, image works fine but in the sound Manager tells me not connected HDMI

    Hello

    I have a 1050ez tm2 and having problems with my HDMI port.

    When I connect the screen gets automatically duplicated and everything works fine, but when I try to play a movie with vlc for example I get not all sound through the TV, only on the tablet.

    Of course, I went into the sound Manager, because I suspected that you specify the tm2 where to play the sound, but to my surpise, he said that the HDMI cable is not connected?

    I was able to make any changes to the default output device...

    Even in the IDT application wants to tell me that the HDMI cable is not connected. I have plugged in and out several times without success.

    I hope someone can help me on what precedes, I already searched the net for several hours but havn't seen a similar problem, the more problems it shows as connected cable...

    Thanks in advance!

  • No sound from speakers - only work helmets

    The speakers certainly work as I hear the rift of Windows to boot top.  Once started, I can't get sound from headphoones.  For about 4 months in this way.  Was OK with it but my kids wanted to watch a movie together and I can't do it with 1 helmet.  I am very computer.  I tried all the basics like reinstall drivers and check all the speaker settings. Called ASUS and the tech rep said that I have to do a system restore to machine original, brand new.  Don't want to do that.  What is the problem of Microsoft?

    using an ASUS laptop f50

    Drivers Realtek - all uninstalled then re-installed

    A run the tool to fix - it to Microsift for sound problems.  It no problem.

    Vista home premium SP2.  All up to date on patches, etc.  I don't run Mcafee - no viruses.

    Well - I ended up doing a restrore system 3 x times - the last time with a Microsoft helps technicians as the thing dang kept crashing.  I have not installed all the updates audio ASUS or Mcafee.  Now I have the sound of the headphones and speakers.

    I not continue on with mcafee on my other machines after the license expires.  Just had too many questions.

    Check if the audio media player is cut in option Volume mixer.
    a. click on the speaker icon in the bar of tasks, and click mixer.
    b. If the media player is muted, and then turn it back on.

    Also, try the following steps:
    a. Click Start > Control Panel (Classic view)
    b. open hardware and sound > sound >
    c. right-click on the speakers and choose the Set as default option.
    d. check if you are able to hear the sound.

  • No sound from HDMI output

    so I just plugged my laptop hp Pavilion in my LCD tv with a hdmi cable

    sounds and music can be played on the laptop when it is connected to the tv, but no sound on the tv at all.

    in my sound playback tabs, the device TICK is out HDMI NVIDIA.

    is there a solution to this? (Help please):

    Hello

    HDMI cables are supported, but not all, audio signals compatible HDMI video audio support cards. If your TV has an audio input, you might be able to connect an audio cable separated from the sound card of your computer directly to the TV. Otherwise, you need to connect the different audio signal to an output device, such as external speakers or your stereo.

  • Equium P300: no sound from speakers but work with headphones

    Hello

    Hmm. You can hear the sound using headphones but you can't hear speakers that well it looks really a speaker problem, but it s really strange that both speakers are dead at the same time

    In your case I would remove the sound card driver and would update with that of the European driver Toshiba page.

I found no other aid anywhere! This is driving me crazy because he used to work very well? If any details are req please let me know. Help, please

    Hello

    This is the email from a friend:

    Establish the connection:

    1. connect the HDMI cable to the computer and television. If the TV has a "DVI/HDMI" port not in use. Use a HDMI port only.

    2 turn on the TV and select the HDMI port you use. Adjust the TV settings to receive audio HDMI if necessary.

    3. turn on the computer. (Optional, some people close the lid of the laptop immediately after hitting the power button, but I don't know why.) Most of the people shouldn't need to do).

    4. optional. Some models are better if the TV is set to the main display. To set, repeatedly press Fn + F8 (or ctrl + alt + F4) to scroll through the settings (laptop display only / display of the laptop with external/external display display only). Reboot the laptop.

    5. go to start > Control Panel > sounds > playback make "HDMI" the default device. (If "HDMI" is not there, right click in the white area and go to the section "Show disconnected devices" or "Show disabled devices" and see if it is there.)

    After connection problems:

    1. If there is still no option to select "HDMI" as default audio playback device, try to re-setup of update driver graphic or even try an older version. "" The graphics driver is the HDMI audio driver, not the audio driver on a regular basis a few people with Intel graphics card had the best results by uninstalling the graphics driver, reboot and let Windows search for a driver (instead of download the Dell printer driver

    support site).

    2. try to disconnect and then reconnect the HDMI cable.

    3 If you are using Windows Media Player or Windows Media Center but don't get no audio HDMI even after that that he is selected as the default playback device, go to

    Control Panel > sound > playback > Audio playback device / > HDMI > properties > Advance > exclusive Mode and uncheck "exclusive mode".

    4. try another HDMI cable.

    5. try another HDMI port on the TV.

    Good luck.

  • No sound from the speakers, but the headphone jack works fine

    Original title: computer with no sound

    My computer has no sound coming from the speakers, but the headphone jack works fine. Can someone help me with this?

    Hi jbreezy,.

    We recommend you to check if the speaker is defined as default playback on your computer device. To do this, try the following steps:
    a. right click on the sound/volume icon in the right corner of the task bar, then click on "adjust audio properties".
    b. click on the Volume tab, click Advanced under Speaker settings, select the speaker and click ok.
    c. click on the tab Audio, audio playback device, select default.
    d. click apply and then click ok.
    e. check if the problem persists.

  • G6-1b70us Pavilion. Picture but no sound from the tv when you use HDMI. Worked without problem.

    I have a pavilion g6-1b70us I'm trying to connect my TV with an hdmi cable.  I get a picture but no sound.  Previously, this worked without problems.  When I shoot to the top of my reading of the sound settings, the only options are speakers and the headphones.  When I shoot to the top of my devices, the Samsung TV is there, but it is described as a "generic monitor" (thinking it was weird).  I have uninstalled and reinstalled my intel graphics driver and IDC audio driver but still no sound through TV.  Also, I will mention that in sub control panel > sounds and devices there is a link to the SRS Premium Sound technology.  As you can see in the image below, the Samsung device is, but it is greyed out and cannot be selected. Can someone please?

    Well in case anyone is interested I have solved the problem (only took me 12 hours to understand, lol).  Apparently, even if the Samsung TV did not appear in the audio options, you can still right click in the empty box and a toggle option will appear.

  • Images are the scale is no longer with (img {max-width: 100% ;}) css from the 34.0.5 in firefox update, it still works fine in IE and chrome.})

    My site was working fine up until firefox updated 34.0.5. Now the images will not scale to fit the box more. I use flexbox so that the site is changing to adapt to the size of the browser. In css, I set img {max-width: 100% ;} and this would make the jpg file size automatically to fit the area they were in, but no more than Mozilla really screwed up this with updated 34.0.5.} My site still works fine with IE and Chrome, but 70% of my web traffic using firefox so I would really like this to work in firefox.
    Any help is greatly appreciated!

    I work by setting a special parameter in CSS for the images that I needed to scale and then I have it referenced by SPAN for each img in HTML, not quite how I wanted it to work since now images filling the box even with monitors really big format, which means that they could now be blurred on a 4 k monitor but firefox left me no choice. Looks like I have going to aid in future chrome like firefox really shit the bed on this 34.0.5 updated

  • No sound from the HDMI connection Toshiba Bluray player BDX2100

    Hello

    I'm a newbie so I don't know if I'm in the right room or not, I want to ask that I have a Toshiba Blu Ray player model number or to number BDX2100 I have set up my fine reader TV and blu ray.

    There is one thing when I play my TV to HDMI 1 or 2, the image appears but there is no noise at all when I go on the Blu Ray in the audio settings menu it says 2nd audio or something to do with the HDMI is turned off.
    Oh I'm 100% sure and my tv is Sharp Aquos LC-22LE320 is not the TV because when I put the SCART lead in or put it on AV it works fine.

    The only problem is the sound with HDMI connection. If anyone can help, it will be very happy because it has been me bloody crazy.

    Hi mate

    It is a Toshiba computer / laptop computer forum.
    You will meet people who want to talk about options for laptops and Toshiba laptops.
    I doubt anyone here would be able to help you with this drive blueray.

    But in your case, I would first check the settings of the TV you.
    Check whether the sound via the HDMI port is enabled.

    > in the settings audio, it says the 2nd audio or something to do with the HDMI is turned off.
    I don't know why 2nd audio is mentioned there but maybe you should check if you can switch this 1 audio (audio main stream) m

    I recommend also consulted this blueray Player user manual.
