I recently obtained an HP Pavilion a1510n desktop with no RAM or hard drive. I put in four sticks of 512MB DDR400 RAM, an HD4350 256MB and a Hitachi 160GB SATA II HDD with Windows 7 Home Premium 32-bit. (Standard specs include AMD Athlon 64 3800+ @ 2.4 GHz.) All drivers appear to be present. However, the audio icon on the taskbar has a red X over it and I'm not getting any sound out of my machine. HP's support site doesn't have any Windows 7 drivers/support (as usual) and I'm trying to look for the driver itself. The motherboard's on board audio is listed as "Built in Azalia 8 channel audio" and "Realtek ALC883 8-channel High Definition Audio CODEC". Does anyone have a possible solution to my problem?
Solution: Well, there isn't one really. However, I managed to get the onboard audio working for a short period of time. I downloaded the UAA HD hotfix from MS (KB835221) and installed the FRE version of the hotfix. Afterwards, I installed the original Realtek audio drivers from the HP site. The audio was working well, but after a restart, the audio was kaput again. I was fed up, so I got a Creative SB Live! sound card used for $10 and I'm having no problems with XP. NOTE: I tried installing Windows 7, but getting the sound card to work is too much of a hassle. Windows 7 doesn't recognize it from the start and some special drivers must be downloaded for it to work.
