Trouble finding right driver for HDAUDIO on Sony VAIO vgn-nr110E for Win 7 -64

I'm just trying to get teh sound working on my laptop. I have installed several drivers, but one device remains unrecognized in device manager.

I have triev installing drivers form sony esupport. Realtek driver installs fine and there is a Realtek HD Audio recognized in device manager, but no sound.

There are no errors and sound appears to work, but I dont hear anything. Again there is a sound deivce unrecognized.

Bring up the Device Manager, right click on the unknown device.

Select Properties from the drop-down menu.

Click on the Details tab.

In the menu box, select Device Instance ID as the item to show.  You'll see something like:

PCI\VEN_8086&DEV_109A&SUBSYS_30918086&REV_00

possibly followed by more information.  See the image below for an example using a known device.

The VEN section is the vendor identifier.  In this case, 8086 means Intel Corporation.
The DEV section is the device identifier.  In this case, 109A means Network Adapter
The SUBSYS section is the specific device.  In this case, 30918086 means Intel Pro/1000 PL Network Adapter.

With these three values, you can Google to find out what the unknown device is.  With that information you can generally find a driver.

It runed out to be a modem (not very useful). Your reply was perfect. Now I realized sound works through the headphones. Any idea how to troubleshoot spreakers? I just tried it with a Linux Live CD with the same results: headphones but no speakers.

Built-in speakers, or external speakers plugged into the green headphone / audio-out jack?

The built-in speakers are ones that are not working.

Yes, and after paying with the soiund controls one speaker works. The other does not even though the volume on the L and R channels is all the way up.

it can be a bad speaker, or broken contact; but to verify that, you need to open the laptop

Ok so I took it apart and didn't see anything obviously wrong with the speaker or contact. I guess I should have read the resistance accross the speaker.

I went ahead and ordered some replacement speakers. They were ony $2.71 with free shipping. Should be here tomorrow. We'll see if that works. I will test the old and the new with the multimeter and see if thre is any differnce while I'm at it.

Yes! When I measured the oms accross the speaker in question it read unity. The other speaker read 33. Not usre what that number means. Read the two new speakers and they were both 33. So I removed and replaced the old with the new and voila, it works!

>>  the speaker in question it read unity  <<  you mean infinity?  that means it is open - no connection
a speaker has a low resistance, ranging from 1to several hundreds of ohms

no 1 = 1 ohm, it looks like a shorted speaker then, if 30 ohms do work
