Realtek audio drivers (intel motherboard) does not work for win 7,

fireberd said:

A previous PC had an Intel Motherboard (older system) and the direct from RealTek drivers did not work in that system. I had to use the drivers supplied by Intel. Same way some older Dell systems require Dell supplied drivers (non-Dell drivers did not work).

not always true.

I installed the Realtek R2.75 (7246) audio drivers on my aunt's Dell Inspiron 580 Win7 x64 desktop computer and they work fine. I even downloaded and installed the 7368 drivers from Microsoft Update Catalog and those also work. perhaps because the hardware ID no. of the Realtek audio device on her Dell PC is included in the list of supported IDs in one of the INF files.

Hi, Erpster,
The details of hardware id as per the download is
HDAUDIO\FUNC_01&VEN_10EC&DEV_0880&SUBSYS_8086E203&REV_1008
HDAUDIO\FUNC_01&VEN_10EC&DEV_0880&SUBSYS_8086E203
As per your post , that is
HDAUDIO\FUNC_01&VEN_10EC&DEV_0861&SUBSYS_8086C601

I think your Intel D915GAV board is not completely compatible with Windows Vista & Windows 7 as there are no specific downloads for those OSes from the Intel web site as I checked myself.

The latest Realtek HD Audio driver provided by Intel for that 915gav board is 5.10.0.5377 posted 3/18/2007. This old driver is WHQL logo'ed, meaning it was digitally signed by Microsoft. You could try to use this old driver. Or you could try to use the 6.0.1.6201 driver from Intel posted 11/4/2010, which was designed for the Intel D101GGC board that I'm using. So it looks like you're using an older Intel board than what I have.

Hi, erpster,
The old would not work, as it is for xp. For Windows only the present Realtek site driver worked which has been given in my replies.
I have done bios clearing as well as cmos clearing to update. Otherwise. No chance.
Hi, Firebred,
If the os is the same, then the old driver should work it, am I correct.
(i mean after restoring the bios and cmos to the stage of buying) please reply firebred. I have tested the recording and it is working in audacity also. Thanks firebred

hi jraju. I had been trying out different versions of the Realtek audio drivers (old and new) on my computer with the Intel D101GGC board and none of them are digitally signed by Microsoft for Windows Vista/7/8. I read the latest R2.75 "readme" file and found out that Realtek made Microsoft WHQL certified (aka. signed) ALC880 & ALC861 audio drivers for Windows 2000 & XP only and not for Windows Vista, 7 & higher.

I think it's best to either do one of the following:
A. Use an unsigned HDA.INF or HDX.INF file on your Windows 7 OS, which mentions hardware ID beginning with HDAUDIO\FUNC_01&VEN_10EC&DEV_0880
B. Use the default generic high definition audio driver provided by Windows 7, which is signed by Microsoft.

I'm okay with using an unsigned Windows 7 R2.75 Realtek HD Audio driver because the ALC880 and ALC861 (most likely ALC861VC, not the 861VD) chips are kinda old and the R2.75 driver seems to work fine on my computer. Plus Intel didn't really provide Windows 7 support for old boards like the D101GGC and D915GAV.

On the other hand, my aunt's Dell Inspiron 580 desktop computer (made in late 2009) has Realtek HD audio using hardware ID HDAUDIO\FUNC_01&VEN_10EC&DEV_0887&SUBSYS_10280438 and that specific ID is mentioned in the HDATHXD.INF & HDXTHXD.INF files. Many versions of the Realtek audio drivers (even ones from different computer manufacturers) also carry the hdathxd.inf and hdxthxd.inf files.
