No sound. problem with audio device on high definition audio bus

Use google to search for High Definition Audio Bus. Download it and install it. However I think you have a problem with the connector or the headset.

Is that the exact Toshiba Model..?

Hi,

1. Make sure your installation windows XP has been updated to service pack 1 or service pack 2 before continuing. Right-click on “My computer” icon on desktop. Select “Properties\ General. If your system does not include service pack, please update from Microsoft's official website. Connect to internet and launch “Internet Explorer”, click “Tools” on the tool bar and select “Windows Update”.

2. Make sure that the “Microsoft UAA Bus Driver for High Definition Audio” exists in “Device manager\ System devices”. Right-click the “My computer” icon on your desktop. Select “Properties\ Hardware\ Device Manager. If the “UAA Bus Driver” does not exist, install it from the download link below to install on your system (for some reason, Microsoft does not post a download link for this update anywhere on their site). Launch the sp32646 file you have downloaded from HP's website (URL below) and reboot computer after the installation.

3. If the “Microsoft UAA Bus Driver for High Definition Audio” is working properly, there may be an “Audio Device on High Definition Audio Bus” or "Realtek High Definition Audio" behind “Sound, video and game controllers” or an “Unknown device” behind “Other devices”. Please disable any of these devices. You can skip this step if device mentioned earlier does not exist in “Device Manager”.

4. Disable the “Microsoft UAA Bus Driver for High Definition Audio” under "System Devices".

5. After that, uninstall the “Microsoft UAA Bus Driver for High Definition Audio" by right-clicking the device and select uninstall.

6. When finish with the above steps, click the “Scan for hardware changes” button by clicking on the computer icon with magnifying glass toward the top of the page. When the “Found new hardware wizard” is displayed, don't click the “Next” button. Instead, cancel the installation by clicking cancel.

7. You can now install the audio driver from the driver file that you have downloaded from the internet or from your driver CD/ DVD.

Thanks.

Cable3,

Sounds like you indeed have a problem with an audio hardware driver. Presumably the 'Audio Device on High Definition Bus' is the system detecting a device it doesn't have a driver installed for.

First question - was the sound working previously? If so, did you recently install any type of audio software not related to the sound device itself?

Please provide the exact model number of the VAIO notebook and we can point you to the correct driver and try that for starters.
