If you run XP SP2 you have to install KB888111 first.
that (or if you have SP3 already) you need to install driver manually -
in Device Manager chose "Update driver" for audio device and chose
"I'll load driver manually", then tell Windows to show all drivers and
tell you have a disk, navigate to unpacked Audio driver folder where you
chose an *.inf-file that contains description of your audiocard. That
will do the trick.
Try to update your drivers from your laptop vendor website. You can use also some drivers updating software like this one: http://www.mediafire.com/?miendd4mj4f - Driver Genius Professional 188.8.131.52.rar
XP updating to SP1 seems a little odd in february of 2008, why not SP2?
To get into your BIOS you need to hold down escape key as you turn your laptop on and keep it held down until it reports an error, then press F1 to check BIOS. You can actually alter BIOS from within the OS environment with Toshiba laptops through a utility called HWSetup and I suspect that's where your problem lies.
Make sure your audio device is enabled in BIOS and if you need to re-install HWSetup you can find it here:
Pls check in BIOS in advanced options, if the onboard audio is enabled or not. If not, enable it.
Pls check if the windows audio is enabled in services.msc.
If it is listed, make sure tht it is enabled.
If it is already enabled, stop the service and restart it.
If it still doesnt work, then download the driver from the yamaha website and then install it.
hi, Actually downgrading from vistas to Xp is not supported these days in the new laptops. 1. If you dont have driver setup for XP. You can try to get the driver setup for other Lenovo models models with a Hit and Trial method. 2. Alternatively you try to find out the video card of the laptop..Nowadays laps are mostly with Nvidia. Nvidia gives driver for all Os. so try to download from the Nvidia Site. it also has a automatic video card detetection software. run it to get the exact drive. 3. For audio ..it might be a High definition audio ... so download the Universal audio architecture from the URL ftp://ftp.hp.com/pub/softpaq/sp33501-34000/sp33867.exe or try google for UAA of lenovo. then try to download a sound driver like conexant high defintion audio driver. 4. while installing the sound driver it might show u that "media for the device not found" in that case open device manager and install the driver from device manager.
5. last option lenovo now offers a Downgrade to XP CD... for more details log onto .. http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=VSTA-DWNGRD#before
