No sound via HDMI output

Model: HP DV5-1225CA with ATI HD3200 graphic card and using IDT digital sound driver. No sound output to my LG HDTV via HDMI cable. Spent 6 hour in 3 days on the phone with the poor HP techs. Last option they offered was sending me a box to ship it back for repair!

    More details:

    My dv5-1225ca doesn't output sound when connected to my LG HDTV via a HDMI cable. I got the green bar flashing on any of the four devices (HDMI, speakers, headphones, SPDIF) as long as I change them as default. Sound just did not want to come out from HDMI or SPDIF on my TV. I wasted 6 hours in 3 days with the useless HP techs and tried everything they suggested, i.e. changing default device, update drivers, update BIOS, even system recovery to factory setting eventually. Nothing worked!

    I asked each of the HP agent the same question: does my dv5-1225ca machine support such HDMI audio output? The answer was always yes! So I thought it is just bad luck getting a broken machine. Within 14 days of purchase, I exchanged it for another one. Same thing!!! I brought home a G60-324ca and it worked (both picture and sound via one cable), so it is not a problem with my TV.

    This is the setting of the dv5-1225ca:

    AMD Athlon X2 QL-62

    ATI Radeon HD 3200 RS780M intergrated graphic

    Windows Vista 32 bit Home Premium

    Driver versions:
    ATI Radeon HD 3200 Graphics

    High Definition Audio Device

    IDT High Definition Audio CODEC

    One last thing, I tried installing the latest ATI Catalyst 9.5 driver. It just screwed things up: it didn't not recognize the HDMI Audio Device any more and showed it "not plug in". Green bar was no longer flashing.

    Any help will be appreciated! Or at least tell me the truth about the hardware: is the machine supposed to support HDMI vedio+audio? Is this a hardware problem or a software problem?

    The next thing I am going to try is to install a XP dual boot and see if it is a Vista problem or not. Any suggestion?

    Microsoft Device Driver Interface for HD AudioUpdated: September 25, 2006

    DownloadMicrosoft Device Driver Interface for HD Audio

    781 KB
    Microsoft Word file
    Updated: Sep 25, 2006
    Get Office File Viewers

    download document presents programming guidelines and a set of
    reference pages for the Intel High Definition (HD) Audio device driver
    interface (DDI). Audio and modem drivers call the routines in this DDI
    to manage hardware codecs that are attached to an HD Audio bus
    interface controller.
    In Windows Vista, Microsoft intends to provide the following drivers as part of the operating system:

    A bus driver for managing an Intel High Definition (HD) Audio bus interface controller.

    Universal Audio Architecture (UAA) class driver for managing a
    UAA-compliant audio codec (or possibly more than one codec) that is
    connected to an HD Audio controller.
    also intends to develop a similar HD Audio bus driver and UAA class
    driver for systems that run Windows Server 2003, Windows XP, and
    Windows 2000. For information about the architecture of the HD Audio
    controller, see the Intel High Definition Audio Specification. For an overview of UAA, see Universal Audio Architecture.
    HD Audio bus driver implements the HD Audio device driver interface
    (DDI), which kernel-mode audio and modem drivers use to communicate
    with hardware codecs that are attached to the HD Audio controller. The
    HD Audio bus driver exposes the HD Audio DDI to its children, which are
    instances of the audio and modem drivers that manage the codecs.
    version of the HD Audio bus driver that runs in Windows Server 2003,
    Windows XP, and Windows 2000 supports two variants of the HD Audio DDI:

    A DDI defined by the HDAUDIO_BUS_INTERFACE structure. This DDI is identical to the HD Audio DDI in Windows Vista.

    A DDI defined by the HDAUDIO_BUS_INTERFACE_BDL structure. This DDI is not available in Windows Vista.
    The differences between these two DDIs are minor and are discussed in the section "Differences between the Two DDI Versions."
    In Windows Vista, the HD Audio bus driver supports only the DDI that is defined by the HDAUDIO_BUS_INTERFACE structure.
    Windows Vista, Windows Server 2003, Windows XP, and Windows 2000, the
    UAA class driver uses the DDI defined by the HDAUDIO_BUS_INTERFACE
    structure to manage UAA-compliant audio codecs. In addition, hardware
    vendors can choose to write custom device drivers that use one or both
    of these DDIs to manage their audio and modem codecs.
    vendors should design their audio codecs to conform to the UAA hardware
    requirements document (to be published). In the absence of a custom
    audio driver from the vendor, users can rely on the system-supplied UAA
    class driver to manage their UAA-compliant audio codecs. However, an
    audio codec might contain proprietary features that are accessible only
    through the vendor's custom driver.
    Included in this white paper:

    This document provides a preview of both versions of the HD Audio DDI. It presents the following information:

    A background discussion of the Intel HD Audio architecture and the Microsoft UAA class driver.

    Programming guidelines for using both versions of the HD Audio DDI to control audio and modem codecs.

    A technical reference that describes the routines in the two versions of the HD Audio DDI.

    I had the very same problem and after 2 days of working on it I found a VERY simple solution. At some point your HDMI audio out was disabled. To fix this problem, click on the speaker icon in the taskbar, and then select mixer. Next, select the "Applications, systems sounds" icon. From there, select the Playback tab. RIGHT CLICK in the box which shows the speakers and other devices. This will now give you an option to view "disabled" or "disconnected" devices. From there simply enable your HDMI OUT device. Hope this works for everyone!!!

I am having a Problem with my video card not letting me run an addition monitor off the vga output on the motherboard. I know it works because I can go to the bios and change it and it works but they want...

When using a PCI or PCI-E graphics card, it will disable your standard VGA output port because the up-dated graphics card and your factory VGA port require different display drivers. Usually, the drivers are conflicting and will make your system unstable and cause it to crash. In short, you can't use both at the same time. I have a Radeon HD 5450 graphics card installed on my PC and it too has disabled my standard VGA port. If you are trying to use more than one monitor, you have to install a graphics card that supports a multiple display output. The graphics card will either have 2 VGA ports, 2 DVI-D ports or 2 HDMI ports or even any combination of the 3. My card, for example, has 1 VGA, 1 DVI-D & 1 HDMI. I can run up to 3 monitors at a time via my graphics card, but I cannot run a 4th monitor from my factory VGA port. My graphics card uses ATI/AMD drivers while my VGA port requires the use of Nvidia drivers.
I hope that you find this useful.

I need mercury motherboard PI945gcm drivers

This is your board:
There are specifications and download tabs lower on the page. You have Intel GMA 950 video and Intel 945GC and ICH7 chipsets. You can try your Intel drivers here:
The biggest problem you are going to have is with the sound. The IDT 92HD202 has been discontinued. You can try downloading driver from Mercury however, you may want to consider an upgrade to a sound card or graphics card. The Radeon HD cards will give you graphics and sound using ATI's DVI to HDMI adaptor:
You have a PCIe x 16 slot so you could upgrade.

No Sound

ATI is the graphics card developer. Your motherboard has onboard audio that appears to be Realtek. You should not have an ATI sound driver... as they don't exist.

I'm assuming you're using WinXP to make thing simple. If you're using Vista, try to do the equivalent.

Since your graphics card is capable of HDMI, the problem could be that the card expects to output audio through your graphics card rather than the sound card. Check start -> Control Panel -> Sounds and audio. -> Sounds and Audio Devices /or/ Adjust Speaker Settings -- go to the Audio tab and make sure it says Realtek for output. If it shows more than one output device, set it to realtek. If it doesn't show realtek, follow the below instructions, and then double check at the end that the Output device is set to Realtek.

1>Please go to HP's site and download their Audio drivers.
2>Go to Device manager -> Sound, Video, and game controllers.
2.1> Does it have an entry saying "Realtek blah blah Audio" there? If not, what entries does it have for audio? Ignore Audio Codecs and Legacy Audio Drivers.
2.2>If there's nothing there, you need to install the drivers you downloaded. If there is something there, please continue to #3.
2.3>After installing the driver, restart computer.
2.4>Once computer is restarted, go start -> Control Panel -> Sounds and audio. -> Sounds and Audio Devices /or/ Adjust Speaker Settings. Hit the button labeled Advanced and adjust the speaker setup to whatever you have - surround sound, 5.1, quad, stereo, whatever.
2.5> Go to #5
3> If there is anything that says Realtek/Azalia Audi, right click it and Uninstall.
3.1> Restart computer.
4>Install audio driver you downloaded, and perform #2.4.
5>Find the driver icon (there's probably on in the task tray) or find it under start -> Control Panel -> Sounds and audio. Set your speaker settings there as well. Audio I/O should specify what ports go to what speakers What you set in windows should match the Realtek audio manager's speaker setup.

If problem persists, please report this.

Ati cga 9258atd

hi freddyboyj,

Firstly I want you to make sure that there are no damage to the connectors of your cables or on the ports on your screen card and TV, like bend or missing/dirty pins/wire connections.

Secondly make sure that the display is enabled in ATi Catalyst Control Center.

The connectors you will be using if I understand you correctly will be DVI-to-HDTV (Component video).

Follow the "click here" link at
for a detailed instruction set of how to connect your Screen Card to your HDTV via Catalyst Control Center.

Kind regards and thanks for using the FixYa service

No sound

The Philips DVP5982 has an odd menu setup for the HDMI sound.
If you get sound from the analog outputs from the unit, but no sound when you use the HDMI output, use this procedure to see if you can restore it:

On the remote control, press Setup.
- Right cursor to the Audio Setup Page
- Go down to Digital Audio Setup
-Right cursor, to get to the screen that shows

Digital Output
LPCM Output
HDMI Audio Setup

Try to go up to the Digital Output setting- if you can't , and instead it shows only HDMI Audio Setup with the "On" highlighted in blue, this is the quirk:

Go into the HDMI Audio Setup, and select "Off", and press Enter, so it's highlighted in blue.

Now it should let you go into the Digital Output menu selection, where you may find it to be on the "Off" setting.

Select "All", and then you can go back to the HDMI Audio Setup and set it to On again, and it should now output sound from the HDMI again.

For some reason, they decided to lock out the Digital Output settings menu when the HDMI Audio is On- go figure.

So you need to turn off the HDMI sound before you turn the sound on.. ;)

LG 42PX4DV - HDMI Audio / PC Audio IN problem

I found the fix. Had the same problem.
I right clicked on the sound speaker icon in the bottom right of Windows 7.
Chose Playback Devices.
Once this window opens, then make sure you are on the Playback tab.
Scroll down until you see the HDMI Device. (Mine was hidden at the bottom of the list.)
Then choose "set as default".
The sound will begin playing on the TV with only the HDMI need for an extra audio cable.
