No sound after installing new graphics card

[james62755]

so today after installing my new graphics card Radeon hd 4850 1gb and new 600 watt power supply i started my computer up just to see if it runs properly not plugging in everything because i was just being lazy anyways i updated the graphics card by downloading the updates from this site ATI Catalyst
and installed all three after i rebooted and plugged everything back into the computer and notice that there was no sound. i guess the sound set so that the out put is for the ati hdmi output ive tryed everything to change it back to original output sound effects manager but it wont work

Go to the Control Panel/Hardware and Sound and finally the Sound panel. In the playback section, reset your speakers (sound card) as the default playback device. That should get regular sound back if the ATI set its HDMI as the playback device.

nope nothing it doesn't come up at all

In the Playback panel, RIGHT click in an empty area and then check to show disabled devices and disconnected devices and see if your Speakers (sound card) show up.

If there is still nothing, go to the Device manager and Uninstall the sound module (DO NOT uninstall the drivers) and then restart the PC and when Windows starts it should detect and reinstall the sound.

Go into the bios and double check that the onboard audio hasn't been disabled. HP being HP I wouldn't be surprised that they have the bios set to auto disable the onboard when a sound card is installed, and the 5670 does have a sound card built into it.
