I have a Lenovo W500 4062-5YG... O/S: Win 7 Pro
My sound device is a Conexant 20561 SmartAudio HD.
The problem is, that the internal speakers have stopped working all of a sudden... I think it is a hardware problem since when I hookup external speakers or headphones they produce sound... but I am no expert!
I have done the following to try and fix it:
None of these actions have worked.
I actually thought I could perform a hardware test on the speakers in the "Lenovo Solution Center"... but it doesn't seem like it:-(
Any help is appreciated.

As mentioned in your post, you have performed all the major troubleshooting steps to resolve the issue. I suggest you to update your BIOS also in order to resolve your issue. You can download and update the BIOS update utility from the below mentioned web link.
Kindly click on Quick path and put your 7 Digit TYPE-Model number(40625YG) in the box and then click on the Find My Product. Please click on BIOS and then download the BIOS update utility according to your Operating System. It might resolve your issue. If it will also not work then it seem to be an issue with hardware. Kindly get in touch with the support centre they will assist you and try to resolve the issue.

I might sometimes have the same problem on my new w520.
speakers just make "tok" instead of playing the sound, then silence.
i have sound out of the jack though.
if i plug and unplug headphones the speakers sometimes start to work again for a couple of days. sometimes the dont.
today i reinstalled older sound-drivers from 2010 and it started working again after reboot.
so this might not be a hardware problem.

This has been covered in detail on another thread. Like many other W520 owners, I had this problem too. It has to do with the way the speakers are wired.This appears to be a design flaw. Perhaps the moderator should make this thread "sticky", based on the prevalence of this problem.
If you want to diagnose it, boot a factory image and see if you still have the problem.
A great solution for the handy who don't want to part with their machine was generously provided by @DavidU86:

hm, why would the speakers start to work again after unplugging from the headphone jack? sometimes sound comes back for a second, sometimes ongoing. if the wire is broken its broken, isnt't it? I will open the laptop tomorrow though to have a look at the wires.

It is possible that you have some other problem. I will say that I had similar symptoms. I would press on the bezel, then the sound came back for a while, etc. After I took of my keyboard and started jiggling the wire, I realized the source of the issue.
Good luck. Let us know what you find out.

I had the same issue on my w500.
I unpluged the speaker's wire, which goes to motherboard( placed under palmrest) and pluged it back. The problem gone for 4 months so far

well, i just opened up my w520 to see if i could find a broken cable. unfortunately the audio cables are covered with shrink cable nearly completely. couldn't see anything.
but now i'm sure its not a software issue, because as i move the thinkpad speakers stop working and start working after shaking etc. its definately a slack joint.
as i dont want to (or am not able to ) replace the cable myself, i will bring it to the nearest thinkpad store before my next holiday and have it done since it falls into warranty. I need it at work everyday.
