Answers:
More details would be helpful such as things you have changed before this happened.

Was it working fine earlier? Did it just happen all of sudden?

Have you checked this?

Go to Start -> Programs -> Accessories-> Entertainment -> Volume control.

Volume is up? Mute is not selected?

==============================...

You might have deleted the driver for your audio. ( i am 99.99% sure if it says you don't have the right mixer )

Go to Sony's website and download the audio driver for your laptop and try reinstall it.

here is the link to Sony's support website.

Search for your laptop and download the sound driver.

I did some googling on your laptop model.

it seems like PCG-TR1AP is the same model as PCG-481L

========================

Here is the link to download your driver.

Install it.
