My PC is HP/Compaq Presario 1950NX and it come with integrated Video Card (Nvidia 6150) and 1G RAM.
Even it has good CPU (Athlon XP 3800) lack of memory and slow video card did not allow me to use high detail settings even on older games.
To improve the performance of the system I’ve added 1G of RAM (~$50) for total of 2G (4x512M).
And added PCI expressx16 video card from DiamondMultimedia Viper HD 2600 XT 512M (~$65).
As usual the upgrade was not flawless.
I’ve disabled the driver of NVIDIA card as noted in installation document that come with the card (always read those documents they contain important instructions) and set from BIOS PCI express as primary video controller.
After that I’ve installed the card and then the drivers from the CD.
Up to here no problems…
But after I started video player I noticed that simply there is no sound. As usual I verified the cables – so many times I simply did not plug them, but everything was OK.
Then I opened control panel -> sound and audio devices to see for my surprise that the sound card was set to none.
Next step was to check Device manager – only one adapter was listed – ATI Function Driver for High Definition Audio…
After seeing this It light up – The Video card has HDMI output and is capable to transmit audio via that connection. This was counted as sound device and since in BIOS onboard audio was set to AUTO it was disabled.
Simply setting it to Enabled bring back my sound.
