Hi,
I have a Sony Vaio VPCEB4Z1E/BQ, I installed the windows that came with him, everything ok except the sound, my build in speakers don't work, when I plug in my external spearks the sound works. Is it a hardware problem or driver problem ? Thanks.
Hi,
i have the same model from last week and i don't have this problem; everything is going well. You should go to service.
Good luck!
hi, I think you should try to re-install the sound driver, it should be worked otherwise hardware problem!

I am searching for the Quick Web Access software for my VPCEB4Z1E, any one can help me? many thanks: inform me via email: johnmatinusa@googlemail.com
Hi John,
You can reinstall Quick Web Access from the Recovery Partition.
Uninstall audio drivers completely and then install the driver that is working.
1. Click Start,type Device Manager in the Start Search box, and then pressENTER.
2. In the Device Manager dialog box, expandSound, video, and game controllers.
3. Locate the audio device that was included with the computer.
3. Right-click the device, and then clickProperties.
4. Click theDriver tab, and then click Uninstall.
5. Place a check mark next to"Delete the Driver Software for this device" check box, and then click OK.
6. Install the driver that is working.
7. Restart the computer and check if the issue persists.
Hope this helps
