nVidia GT 520 rendered onbord sound card useless?
Greetings to all,
the machine in question is HP dc5850 (Phenom X4, 8GB RAM, Windows 7 x64) machine that had Quadro NVS 285 card inside. Due to some requirements, machine had to be equipped with CUDA capable dual monitor LP card. Since price *did* matter, I obtained 70$ worth PoV GT 520 card and HDMI-DVI adapter. The moment I inserted the card, I lost onboard Realtek HDA and got two "Digital Audio (HDMI)" playback devices. http://tinypic.com/r/6z90g7/7 http://tinypic.com/r/2lk7ig2/7 I tried multiple solutions (changing drivers, various hacks for disabling HDMI Audio, etc.) but nothing helped. Apparently, there should be an option to disable audio but I seem to have none on my card. http://tinypic.com/r/1498qk8/7 Any help is appreciated. TIA! -- "If you lie to the compiler, it will get its revenge." Henry Spencer 2.718281828459045235360287471352662497757247093699 959574966967627.com |

Go to Control Panel, Sound and Audio Devices, then Audio properties tab, then choose your default playback device. I gave you the exact screenshot of that tab and it consists of (nVidia) HDMI Audio devices only. http://tinypic.com/r/2lk7ig2/7 -- "If you lie to the compiler, it will get its revenge."

I gave you the exact screenshot of that tab and it consists of (nVidia) HDMI Audio devices only. http://tinypic.com/r/2lk7ig2/7 Have you tried looking in Windows/inf/setupapi.dev.log ? It looks like a record of the installation of hardware devices. I don't know if a separate error log is kept anywhere. Event Viewer would be a traditional place to look, but I never seem to see anything interesting in there. I looked at both a RealTek driver package and a freshly downloaded NVidia one for a GT520 for x64, and both of them use proper VEN and DEV codes. Nvidia VEN is 10DE and RealTek is 10EC. So it's probably not direct interference of one driver installer with the other. In Device Manager, you have options such as "Roll Back Driver" if you just installed a driver off the Nvidia CD. (Roll Back only works to one level, so isn't likely to work a year from now.) Another option would be to "Disable Device" in Device Manager and get rid of the Nvidia that way. Then try reinstalling the RealTek. I had two sound devices under WinXP, and had one of them, "shoot the other one in the foot". There was a registry setting that one sound device checked for, and the other one wrote a bogus value in the registry entry. Once I found it using sysinternals.com procmon, I could correct it such that both sound devices would work. The installer for the failing sound device, would not write the registry for that key, but the software did check for it later. It was intended to make the first driver "defer" to the second one. But once I discovered which registry value it was, I could set it up so both hardware drivers worked, and I could select either one as the output. http://technet.microsoft.com/en-us/s...rnals/bb896645 You don't really want to do that, but that's an example of how much trouble you can go to, to fix the sound. Watching filtered registry reads, with Process Monitor. And noticing "mixer.exe" dies, after a certain registry entry is checked. Paul |

Paul's log on stardate 15 srp 2011
Have you tried looking in Windows/inf/setupapi.dev.log ? Never knew this one existed. Great tip. Unfortunately... It looks like a record of the installation of hardware devices. ....it doesn't shed any light on my problem. /snip I was really frustrated, so I took a whole day and this is what happened - it seems that (I *really* don't know how) by putting GT 520 to PCI-E slot onboard Audio gets disabled in *BIOS*. Reenabling it does not help, however, this is how I did it: i) removed GT 520 and started Windows with onboard ATI card ii) removed all drivers iii) reenabled onboard Audio in BIOS iv) reinstalled Realtek drivers v) returned GT 520 vi) enabled onboard Audio in BIOS once again Now it works. Huh? Anyhow, thank for your time! Have a nice weekend!¸ -- "If you lie to the compiler, it will get its revenge."

Thanks for reporting back :-) The BIOS shouldn't really do that, but then, the BIOS used to do stuff like that for video in some cases (installing an add-in video device would disable another, when they really all could have been left running). If the BIOS was consistent, you'd think it would also disable your onboard ATI as well. Paul |
