Question about Graphics Cards

No Sound After installing the video card ''ATI Radeon HD 2400'' I no longer have any sound. I am connected via this card to the monitor via a DVI cable. I am running an HP media center m7250n pc with 3gb ram, and at least 100 gb of hard drive room left.It is an Intel Pentium D 820 dual processor at 2.8ghz. I run Win XP SP3. The Device manager says Everything is ok annd that the ATI sound driver is enabled.

I tried everything to uninstall the sound driver but it would keep coming back and my Realtek driver would never appear in the Device Manager list even after installing it. Finally I removed the unwanted device driver in safemode and re-installed the former driver I had for Realtek. Then instead of uninstalling the ATI HDMI sound device I just disabled it. It fixed everything.

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.

    Ah, glad it worked in safemode. I should have thought of disabling the HDMI sound device... Great that you figured out the rest of how to fix such a stubborn problem. I'll have to remember that myself... nasty bug.

The video processor no longer operates - the lines are caused by the simple operation of the timer clock of the processor. The card is dead and you must replace it.

Make sure you have the Catalyst Control Software installed and set to advanced mode. When you open the program and go to the settings for multiple monitors. There is a box that needs to be checked on the VGA option that allows it to be on always.Here is the support link where you can find the software http://www.amd.com/us/products/desktop/graphics/ati-radeon-hd-3000/hd-3400/Pages/ati-radeon-hd-3400-overview.aspx
