Thanks, it works, but I don't I wnat to do it everytime I start up my T430.
Does any fix for this issue from official?
Is this referring to disabling Intel Display Audio?
If so this is a one time operation. It will stay disabled through a reboot etc.
As I explained Intel Display Audio is not needed unless you want to output audio via the mini display port connector.

I know this is an old thread, but I have also been experiencing intermittent sound speaker failure.
Sound would work for an hour or two, then just stop.
I had been refreshing Pandora website several times to get the sound back.
I followed BrianG61UK suggestion of disabling "Intel(R) Display Audio" in Device manager.
Behold, the rain stops, the sun comes out, the music plays.
Thanks for the marvelous tip.

Other things that may be worth trying are:
a) Update the Lenovo Power Management Driver to the latest one for your PC model and Windows Version. Download it from Lenovo; Windows Update could give you an old or generic driver.
b) Simplifiy your Power Management settings. One thing that can mess up the sound is when power settings change automatically due to things like changing to/from AC power from/to Battery power.

On my T430 running Windows 7 (64 bit) the problem of losing sound seems worse with the latest 188.8.131.52 Power Management Driver.
For some time everything had been working right with "Intel(R) Display Audio" enabled.
With the new 184.108.40.206 Power Management Driver I lose Internal Speaker Audio soon after booting on battery power .
So I'm back to running with "Intel(R) Display Audio" disabled again.
