Sound is more output via HDMI

Hello

I have a desktop HP m9300t with Vista 64 Bit SP2. It has a video card Nvidia GeForce 9300 256 MB with a HDMI output (and DVI).

I've always been able to play the video and sound through an HDMI cable connected to my TV. A few weeks ago, I ran a few updates and uninstall several programs I do not use or need. I installed the Vista SP2 and updated my nvidia driver for the last available on the nvidia website. Now, I can only video output via HDMI, but no sound.

I have the Realtek HDMI output defined as the default device under sound-> read (and it shows like 'work'). When I test it, I can see the volume up and down bar, but there is no sound on my TV. I also tried many different programs (WMP, Winamp, Media Player classic, Firefox, but still no sound.)

Sound works fine in my computer speakers when I put as device by default.

I tried two different HDMI cables, which I know work because they took out his other devices.

I've updated my audio driver for the last available.

I installed an older video driver without success.

I scoured the internet for hours, but nothing I can find solves my problem.

Hello

Check the device settings in device that receives the stream of video and audio HDMI.

What camera brand and model has no sound via HDMI?

What is plugged into the SPDIF Jack on the back of your PC, no matter what?

Go to www.realtek.com and download and install the latest audio driver.

Go to www.nvidia.com and download and install the latest video driver.

You could also try to uncheck HDMI and check digtial output and see if that produces sounds.

These "how-to" HP articles can also provide assistance.

Even the latest drivers and updates may cause the problem.  I have run into a problem of sound with Realtek and had to fall back to the original audio driver supplied with the PC to get his job.  Five months later, Realtek audio driver problem fixed.  You need to maybe do this or maybe go back to the last good Windows restore point known. Of course if it does not then you would have to depend on your image less hard drive backup.

It is also possible that your HDMI audio circuits are bad.

  • R830 satellite and video output via HDMI

    Just wondering if it is normal that my laptop for a max of 1280 x 768 HDMI to my TV LCD 26 '' exit?

    Its an i3 Satellite R830 with graphic hd3000. I have 8 GB of RAM. Tried on Windows 7 and 8 but the same thing.
    I tried custom resolution, but he's also saying on the TV out of reach.

    MT graphics driver is up to date and I got full HD working on this TV via another laptop old.

    Any suggestions please?

    I don t know your LCD TV listing, but always is he that external resolution depends on three options:
    driver graphics card, graphics card and the external device connected to the computer/laptop.

    So if your TV does not support a higher resolution, you will not be able to choose another resolution.
    If your TV supports a higher resolution but the graphics driver and the graphics chip would not support a higher resolution, you also won't be able to use it.

  • Dolby Digital Audio output via HDMI on Satellite A200 cable?

    I don't see how to get a Dolby Digital signal on my laptop!

    I have a screen LCD HD 1080 p television. With the help of a cable HDMI from laptop to TV gives a beautiful image. I then use an optical link between TV and Surround amplifier... However the amp does not recognize the signal as a Dolby Digital signal.

    The record is not clear on issues of Audio. The Toshiba HD-DVD player shows Dolby Digital option and I guess that's out put down the HDMI cable? I hear through the TV speakers.

    Hints would be much appreciated.

    Hello

    To be honest I didn t know that there is Satellite A200 laptops with HDMI output. Can you please tell me what A200 you have (A200-xxx)? Are you really sure have an A200?

    Back to your problem: as far as I know the Digital Dolby audio can be sent if the laptop has S/PDIF port. You must also use an optical cable and connect laptop to your amp directly.

    What you do now is send the signal to the TV only. I don't really know if you can browse the Dolby signal to the amp.

  • Channels disappear in WMC at the output via HDMI

    I have a tuner TV USB (connected to an internal antenna) on my Windows 7 laptop. When I use just the laptop, I can watch TV without any problems. However, when I connect the laptop to a monitor via a HDMI cable, all channels disappear and running a scan does not find an any of them. Help the PC on the screen works fine - just Windows Media Center is not.

    The laptop is a Dell Inspiron M301Z and the TV tuner is a DVB-T205 August (v2.0).
    Someone at - it just an idea as to what might happen?
    Thank you

    This may or may not be related but I was also faced with HDMI and TV on Media Center and Media Player playback.   You say that using the HDMI interface as a PC monitor works fine, just that WMC or MP do not play TV Live (I guess that's what you mean by "channel disappears").   I encountered the problem that I can not play back recorded OTA TV via the HDMI port, but it works fine on the computer screen, just as you describe.  I have not tried to directly play live TV like this so I do not know if this also fails.  However, I discovered that WMC and MP read properly on the TV connected via the analog VGA port on the laptop.  You can try to hook up a monitor via VGA and then try to watch television on the subject.  In my case, the HDMI connected TV present a good computer bureau and icons, etc, but when I tried to play recorded TV, Media Player won and gave me a message about missing files.  I find that VLC Player works with HDMI, but it does not play HD as well as WMC material due to its fine use of the acceleration of graphics chip.

    If your tuner key comes with the TV/DVR software (most of them do), you can also try to run that and see if it works on the HDMI monitor.  I posted a query on this forum about the problem I found in mid-October ("Mirrored display causes error CODEC... "), but no useful response so far.

    1. fix a TV to the laptop via HDMI, while both units are in a * "power" off * State.
    2. turn on your TV first, then the laptop.

    4 launch Sound (start (Windows logo)-> Control Panel-> hardware and sound-> Sound)
    5. on the playback tab, select "Peripheral digital output (S/PDIF)" and click on "Set as default"
    6. click on 'Apply' then 'OK' to close his
    7. the sounds played on the l should now also be heard on the TV (keys Fn + ESC or the volume dial can be used to cut the sound to the computer)

    _Please Note: _
    1. peripheral digital output (S/PDIF) installation default through Volume mixer does not output digital audio via HDMI.
    2 HD DVD-video can only be displayed on the LCD of the computer bulletin board or on a television connected to the output of HDMI port. HD DVD Video cannot be displayed on televisions connected to the S-Video port or an external display connected to the RGB connector.

  • No sound via hdmi

    Hello

    I have a hp dv9000 with hdmi output.  I signed up for Netflix and connected the laptop hdmi cable to our TV.  Use of IE, I started a film and the video is very good.  The sound of the film is coming through the speakers of the laptop, but not the tv.

    Curiously, the windows sound is coming through the tv speakers and not the laptop.

    How can I get the sound of the movie to play through the TV?

    Hello Bulverde,

    By default the Vista transmits no sound on HDMI output.  To change this to change the settings in the control panel.

    Note: This will turn off sound from speakers or normal audio output on the laptop.  To get that back, you will need to reverse this process.

    1. click on the button 'Start '.

    2. click on "Control Panel."

    3. 'Control Panel Home' click 'hardware and sound '.

    4. where it says "Sound" in green letters, there are three options below that are in blue, click on "manage Audio devices".

    5. This will bring up a window titled "Sound".

    6. on the tab 'Read' it has listed the sound options at your disposal. It should read "peripheral digital output (HDMI)" click on it.

    7. it should now check this option box.

    8. the sound should play through your HDMI connections to the TV.

    You can also see the article that will give you more information on this.
