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.

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?
right click the speaker icon in the system tray, and select playback devices
from here you can select, and configure  the device by right click>properties
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.
yep - if you test them on ohms - you should hear a clikc
you can try that on th old ones now even
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
I meant "1" Is that infinity?
no 1 = 1 ohm, it looks like a shorted speaker then, if 30 ohms do work
Ok. Thanks for all your help!
i'm happy to have been able to give a bit of help
