The Portege T110 is not known to me… but it looks like this series has been released in Asia.
So checked the Toshiba Asia page and found this:

There you can find the Portege T110 and the Win 7 drivers.
The notebook seems to support the Conexant sound driver… so download this and install it on the system.
