Upgraded Toshiba Tecra from XP to Vista,now Sound don't work

June 23, 2012 at 16:44:33
Specs: Windows Vista
I recently upgraded myToshiba Tecra L2-S022 from XP to Vista, and now I can't get the sound working again. Can anyone please tell me where I can find Toshiba Tecra Drivers for Windows VISTA? On Toshiba's website, they only list drivers up to Windows XP. If anyone can help, I would greatly appreciate it.

Tecra L2-S022 (home support page)

"Conexant Audio Driver for Windows XP"

The Detailed Specs do not state which model of Conexant sound chip it has.

Conexant Support

They do not have audio drivers available.

Your model also has a Conexant dial-up modem.
They DO have drivers for that, but not for Vista and up
You can identify which type you have here:

Download this, run it, see if it identifies your Conexant sound chip model.

SIW - System Information for Windows

If it does, use that info to search for sound drivers on the web.

Your info in response 2 does not jive with the info about the drivers / hardware devices on your Tecra L2-S022 on the Toshiba web site.
It's extremely unlikely that you have that sound adapter, unless you have an external sound adapter plugged into the laptop. Creative / Sound Blaster sound chips are not used for any other brand's sound adapter other than their own or OEM versions of their own, as far as I know - I've never come across one that uses (a) Conexant chip(s). Some mboards have a Creative sound adapter built into them, but that does NOT seem to apply to your mboard.

Some software that is supposed to detect hardware devices will find info that was installed in Windows by the user installing the WRONG drivers !

Look in Device Manager - RIGHT click on the entry for the sound adapter that has the problem, choose Properties - Details tab. That's always the PnP ID string string for the actual device, even when you have installed the WRONG drivers.

I suspect the VEN..... part of that is different from what you found.

If the VEN..... part of that is identical,
- if you're NOT using an external sound adapter, there is NO info about your mboard having a Creative sound chipset built into it on the Toshiba web site.
- OR - if you ARE using an external sound adapter
... in either case you can get the proper drivers from the Creative / Sound Blaster web site, for SB Live ! As I recall, there is something there that will dtect which specfic chipset you have. If not, you need to find the drivers for the SB Live! one that uses the EMU10K1 chip(set). Note that Creative / Sound Blaster has many regional web sites - you may find the proper drivers only when you access the regional web site for the region your computer or external sound adapter was bought in.

If you ARE using an external sound adapter,
- Windows allows you to have more than one sound adapter connected to the mboard, but it can only use one of them at a time.
- you DO NOT need to disable the sound adpter built into the mboard in order to be able to use another sound adapter, although if the sound adapter that is not built in is made by the same brand as the built in one, that's probably a good idea.
- only one of them at a time is listed in Device Manager
- the sound adapter you installed the drivers / associated software for last becomes the default sound adapter. You can change which one is used by default in the Sound settings in Control Panel.
- if you have e.g. 2 sound adapters, if you want to be able to use either sound adapter, if the drivers / associated software for the sound adapter(s) is (are) not built into Windows, you must install those

The only changes I've made to the laptop was to upgrade it from XP to Vista Home Premium. There is no external sound adapter. I used 'Unknown Device' software to identify the drivers. I had installed a driver from Toshiba's website, that does not work. It is apparently for windows xp and is not working with vista.

Here is the info from the Device Manager. Hope this helps.

Thats very different from the info you found when you used the 'Unknown Device' software.

Some such software will find the info for the hadware devices in the info for the drivers that have been installed, not necessarily the hardware devices the computer actually has. If the wrong drivers have been installed the software will find info that doesn't apply to the hardware devices on your computer.

If you have any listing for Creative or Sound Blaster or SB Live! software in Control Panel - Classic view - Programs and Features, uninstall that.

The actual PnP ID for hardware devices is the part of the string VEN.....

How many sound adapters are listed, unknown and known ?
Some computers have more than one built in.

For my desktop computer I have two sound devices listed in Vista's Device Manager under Sound, video, and game controllers

Under Details in it's Properties....

AMD High Definition Audio Device (built into the AMD main chipset)

Hardware IDs


High Definition Audio Device (Realtek onboard video)

Hardware IDs


I'm aware that there are no drivers listed for your sound adapter that were meant for Vista - you told us that in your first post, and I confirmed that when I looked at the downloads for your model.

There is not enough info in the support for your model on the Toshiba web site to identify which Conexant sound chipset your mboard has.

Try installing the SIW software and running it as I asked you to - see response 1.

Thanks for all your help. The problem I am experiencing appears to be due to windows vista not being supported by Toshiba for this model Laptop. Guess the only thing to do is to keep searching the internet for a Vista driver that will work with this computer.

See response 1 !
If SIW can identify the sound chip, then Vista drivers for chip can be found on the web !

Well, no thanks. I don't want to have to pay for this... I'm sort of partial to using 'free' apps. The Device Manager shows my Audio Device Hardware, now I just need to find the correct Vista driver for it.
Thanks again for all your help

SIW just finds info.

It's not one of those bogus driver finder prorgams you have to pay for.

Device drivers are always free somewhere on the web, but sometimes it's hard to find the right ones yourself.

Try this.....

Go to All Programs - Windows Update

Click on Check for updates

Then click on the optional updates link

If there is an update listed for the audio, select it and try installing it.

I looked at the contents of the download for the Conexant Audio drivers for XP for your model with Winzip..

In the tosEW5a.inf file it says....


Copyright (C) 1999, 2000, Conexant Systems, Inc.
; INF file to install a WDM driver for AC97 Audio device



PCI\VEN_8086&DEV_266E&SUBSYS_FF311179 is the Plug-n-Play ID string for it.

I searched on the web with that and found it's called
Conexant AC-Link Audio

Unfortunately, there are many different sound chips that have that label - I found no drivers that mentioned a PnP ID string with all of : _266E&SUBSYS_FF311179

You were right, SIW is free. I found a free version on their website,and downloaded it. Now all I have to do is figure out how to use it.

I'll check windows update for an updated driver as you suggested, and let you know if that worked/
