Windows 7: SigmaTel High Definition Audio Codec

I also have the Sony VGC-RC110G and am not able to get sound. There is a Sigmatel onboard device and Sony will not support it for windows 7. Vista is supported but the driver does not work for Windows 7. I even tried putting a new card in and Windows 7 will not recognize it. Has anybody had any success in finding an audio driver for the RC-110G that will work on Windows 7?

Sony eSupport - VGC-RC110G - Software Updates & Drivers

Worked for me downloaded and installed fine. Windows 7 32 bit Profession (not my machine a clients.)

if you still need the info i can get my working drivers to you. I am using a Sony VGN FE880E with Windows 7 Ultimate 32bit. I have had no trouble other than, most device driver program (updates) provide an IDT update which has never worked for me, and somewhat less that outside volume, I use external speakers so that helps.
STDAUD-01334805-US, STDAUD-01487700-US and STDAUD-00157222-US. Installed in that order as they files are the original driver installed by Sony, then the nesxt two are suspequent updates to the original. I have gone back to this driver set many times in the time ZI have ran Windows 7, as no other drives seem to work for me. PS Iget them from Sony esupport at the follwoing URL:

i had the same problem with my Micron T2300...install the old driver from windows xp..it worked for me. good luck

Oh snap!!! Finally!!! I have had the same problem ever since upgrading to Windows 7. I came here looking for help. And after months of pulling my hair out and ridiculous web surfing.... I found an actual solution!

Ok so the motherboard for the RC110G is listed as: 945G

If you go to the Intel site, there is a download specifically for it. Granted it took a lot of research, but I now hear everything perfectly. Wow. Months of clicking and popping and horrible sound gone. I know this has been a problem for too many. I'm totally doing the dance.

I can't link it as a download for some reason, but this is the verbatim download file: AUD_allOS_6106_PV_RTL

Search it at Search Options

Hallelujah.


**Actually found a download link on this page: http://http://www.radarsync.com/drivers/d193475-realtek_high_definition_audio

I cant believe this thread is still alive. Thats Great, ....It shows people are using the search feature. ;D

SFCMGIBBS,
Thanks for the information - I also have the Sony RC110G and wasn't gettng the sound card to work. I went to the link you provided and downloaded the driver, and now I'm getting sound and no errors. The only issue I have is that the volume is very low (even with everything set to maximum volume). This may be an issue with the speakers built into my Sony monotor that came with the system (I've always used external powered speakers before, but it would be more convenient to use the built-in speakers in the PC's current location). But it seems odd that the sound is barely audible at maximum volume. I don't need surround sound here (no center or rear channels), but it would be great to have more volume available when listening to a CD or on-line music, etc. Any ideas? The Radarsync application that was downloaded to my PC when I followed the link suggested I update PCI drivers, etc. I'm wondering if that might be related (I didn't do it - it suggested updating 19 drivers, and I was hesitant to make a bunch of changes). In any case, thanks for the help.

I know this post is rather outdated, but I just found a link that got my Sony VAIO working again with the Sigmatel HD audio codec on Windows 7. Just follow the link! ftp://ftp.vaio-link.com/PUB/DOWNLOAD...1487701-UN.EXE

The forum I found this on was: Vista SP1 Compatible IDT/Sigmatel HD Audio drivers follow-up - Computer Hardware Help | DSLReports Forums

Hope this helps! I know it's good to get mine running again!!!!!!!!!!!!

Alternative audio solutions that I have found work on SONY VAIO VGCRC110G

• Use an external USB audio adapter. Some need no special driver for basic sound (plug and play built into Windows 7), others such as Creative require drivers to support advanced features. Advantages: doesn't take up any internal card slot, and this model VAIO has lots of USB ports anyway.
• Install an add-in sound card that works with Windows 7 -- I installed an old eDio Live Theatre 5.1 SC3000D PCI sound card that I had in my junk box -- to my surprise manufacturer has a full suite of drivers available for download, so it works without any problems in Windows 7.
• Install an upgraded PCI-E graphics card (the factory ATI Radeon X300 has only 128MB RAM and is rather limited, works OK with Windows 7 but very basic with Linux) with HDMI output including audio via HDMI. I recommend buying a silent (fanless) card because the original was also fanless and this is a very quiet PC, and also because in this PC the graphics card orientation has the heat sink upward, allowing heat to rise nicely by convection. I'm using a silent Gigabyte 1GB card based on the NVIDIA GeForce GT610 chipset. Note, however, that the large passive heat sink blocks use of the adjacent expansion slot, so I put an eSATA port there (see below). The HDMI solution requires external hardware that can accept HDMI digital audio and convert it to analog for speakers -- Easy if using an LCD TV with HDMI input as one of the displays.
• Use a different operating system: Linux MINT 14 MATE natively supports the built-in motherboard audio, as well as the add-in card and HDMI graphics card that I installed.

I recommend removing the TV Tuner card to free up a PCI slot -- no support for it under Windows 7 anyway, so it permanently has alert indications in the Windows 7 Device Manager, and doesn't work.

While at it, this VAIO has 4 internal hard drive bays and SATA ports -- if you don't need some of them then bring out 1 or 2 to rear panel as eSATA ports -- Monoprice.com sells a dual eSATA bracket. Caution: internal SATA cables are locked to motherboard, must gently release locks before pulling off cables!

Further to my previous comments, I tried the STDAUD-01487701-UN.EXE driver installer in Windows 7.
During installation, it shows itself as IDT Audio, not Sigmatel, and it is also identified as IDT Audio in the Add/Remove programs list, but it appears as Sigmatel HD audio codec in the Windows 7 device manager.

It took an exceptionally long time to install, but the device error did go away. After restart the built-in sound worked, but it was barely audible even at high volume. Then I tested it in Linux MINT and found it works, but likewise is barely audible. So I reverted my setup back to using my add-in eDio PCI sound card.
