Audio drivers for downgrading to xp on AR51M

evilenglishman — Fri, 04 Jan 2008 01:34:18 GMT

Hi
today I got my new laptop and my first job is to get XP on it.
I have managed to get practically everything working in XP except for the audio. I've been looking all over to try and sort this out but no matter what I try I cant get it working.

Ive tried the vista drivers and drivers from various places.

I currently have 2 problems.

1. Pop up on windows start:

Rthdcpl - EAccessViolation

2. SigmaTel High Definition Audio CODEC - yellow ! in device manager with error 10 - device cant start.

Can anyone point me to some drivers that will work?

Hi evilenglishman and welcome.

Have you installed the UAA High Definition Audio Class Sound Driver (KB835221). This is needed by XP to be able to recognise your sound driver.

I attach it here - just run the .EXE

Hi There
I managed to get that last night and it has stopped my SigmaTel High Definition Audio CODEC error 10.

I still have the Rthdcpl - EAccessViolation error though

update:
I downloaded the AR2 drivers from the vaio site which seem to work and i am now only missing a realtek driver. My audio is working but any realtek driver i install seems to give me that same error on reboot:

Rthdcpl - EAccessViolation error

any ideas?

I also have a "network controller" missing - not sure what that could be at this point as the modem, bluetooth and ethernet is working.

Dear All AR51M users,
I have had a terrible time trying to get XP-Pro onto my VGN-AR51M laptop.
But at last I found a LINK that unlike all the others did the trick

LINK-1
http://www.howtogeek.com/howto/windows/resolving-setup-did-not-find-any-hard-disk-drives-during-windows-xp-installation/

And LINK-2
http://www.howtogeek.com/howto/windows-vista/install-windows-xp-on-your-pre-installed-windows-vista-computer/

I purchased two of the AR51M’s one for the Office and the other for the Studio,
The Office one still has Vista at the moment but only for experimental reasons.
The XP-Pro AR51M is running nearly twice as fast and consumes about half
The battery life.
The Vista runs worse and slower than me HP 17” laptop now four years old.

The way to explain the difference is this:
A Sony Vaio VGN-AR51M laptop with a XP OS, is a remarkable Laptop that is very impressive.
BUT on the other hand !!!
A Sony Vaio VGN-AR51M laptop running on Vista is very disappointing and if I was an honest reviewer then I would only give it 2 stars. **.

Now the problems that I still have are drivers for the
Network Controller,
The WiFi
The Audio
&
The Video Controller VGA Compatible.

I will keep you in touch if you wish on the final outcome before
I downgrade No2 VGN-AR51M

Best Regards
And in anticipation thanks for any help anyone can supply me.

Hi
I have almost completed Vista downgrade to XP Pro on my AR51E
My one remaining unsolved driver issue is the Sigmatel sound
and the only device left is a " HD audio codec"

Re: Audio drivers for downgrading to xp on AR51M

SHAWMARTIN — Tue, 15 Jan 2008 08:06:44 GMT

my apologies - I posted without finishing !!

further to my last :
I do not as yet have sound - evilenglishman can you please advise which
method/driverset you used to install on yours ?

One more little glitch is that using standby generates a BSOD - is anyone else
suffering from this ?

many thanks
Martin Shaw

Dear Martin,
First Go to "Control Panel" then "Add & Remove" and remove
kb835221
If you have not installed kb835221 then don't worry
If you have, and you can't see it in "Add & Remove"
Click on Add/Remove Windows Components it should then show itself.

Second go to
LINK
http://geekswithblogs.net/lorint/archive/2006/06/11/81540.aspx

And download the later Driver kb888111 for your version XP

Third Go to "Control Panel" then "SYSTEM" then "Hardware" then
"Device Manager" and uninstall Realtek

Next go to this LINK
http://www.megaupload.com/?d=O29PZ470

And download Audio.rar

Install this,
With my AR51M I got my sound

This has been through a lot of help from others on this Forum
all I have done, is used a bit of advice from each

I would like to thank
geekswithblogs & Надіслано Danath о 8 лист

Now can anyone supply a driver or help me get my Eject -FN Buttons working
& my
NVIDIA Display driver working correctly

I would be most grateful

Best Regards

Hi clembo37 and welcome.

The camera driver is the same for Vista and for XP so use your existing camera driver.

You will need the VAIO Camera Utility which is part of the 'Original XP Utilities Package' downloadable from the VGN-AR21S XP downloads page here: -

Dear Blencogo,
First let me say thanks for all of the time you are putting in to this
club to help others
Many Thanks

I assume if your LINK for the Camera Utilities points to or suggests using the 21S Camera Utility, does this mean that the original 51M driver will work but the original 51M Utility won't.

I have not checked my camera yet,

The poor scrolling screen was the worst problem I had but thanks to Laptopvideo2go and all their hard work my screen is fine now

Just my FN, EJECT, Volume, to be fixed next

Have you any suggestions.?

I am at the moment checking out the Sony Asia Site
Where they have done what Sony Europe should have, trouble is their model No's are all differant

Dear VGN-AR51 Downgraders,
Forget the Realtek Driver, when this is installed it stops the Audio from Working on my AR51M.

If after you have managed to get your audio working and then it stops working, this because Realtek has re-installed itself Via Windows Hardware Wizard.
Go to "Control Panel" then "SYSTEM" then "Hardware" then
"Device Manager" and Disable Realtek

Your Audio should return, make sure that "Sigma" is still there.

Best Regards

Tony

Certainly on my FZ11Z, you needed to install a Windows Hotfix to get the audio to work correctly. No problems at all.

Dear AR51M Downgraders,
I now have everything working except my CD Eject, and my Screen Control, the rest of the Buttons are fine.

I had to sought out something regarding the "Poorly Designed", "Awkward to get at" mechanical way of ejecting my CD's DVD's.

Surfing I came across this page, LINK,

http://www.vicman.net/cd-eject/index.htm

No trouble at all simple and works a treat and it is free but I sent $5 USD

The odd problem I have is, when using an external Amp for my sound, the AR51M speakers are still on
Anyone know a fix for this

Best Regards,

Tony

Dear Blencogo,
Thanks, your TIP Paid Off, my headphone socket is fine now

I am now down to just one problem, which I do not worry to much about.
That is FN Screen Control.

I have (Keystroke) software that works my EJECT, but it would be nice to get the Sony EJECT button to function, if not I,ll stick with the (Keystroke).

Best Regards,

Tony
