Windows 7: Dolby Enhancements Tab is missing

Windows 7 Home Premium 64bit
Dolby Enhancements Tab is missing

After getting my Toshiba laptop, I checked the speaker properties. I did this by right clicking the speaker icon on the taskbar and clicking on playback devices. Then on the resulting window, I double clicked on speakers (My default playback device). In the next window, there was an tab called Enhancements where I could select effects like virtual surround soung, bass boost and loudness equalizer.

I recently formatted my computer and since I got it back that tab is missing. Instead of the Enhancements tab there is another tab called Dolby. Under this tab there is just 2 options that i can tick; Audio Enhancer and Disable all enhancements.

Is there any way I can get back the enhancement tab that I had before because the effects in that tab really helped improve the sound quality of my laptop? Is it something wrong with my drivers?

I tried updating my sound card driver but it still did not work.

Here are my specifications of my laptop if that helps:

Toshiba Satellite L655-PSK1JE05R00XAR
Core i5-450M 2.4 GHz
My sound card driver is Conexant CX20671 SmartAudio HD

I need some help with this problem

Are you using the Toshiba supplied sound driver? If not, give that a try. Non-Vendor drivers sometimes either do not work, do not work correctly or do not have all the options.

BTW, I tried to look up that model and the number doesn't come up on the Toshiba site. There is no L655-P model listed.

Yes I am using the Toshiba supplied sound driver...and i tried updating it from the Toshiba site in order to fix this problem. But it didnt work.
Sorry that PSK1JE05R00XAR is the part number for my laptop

So the full model name is Toshiba Satellite L655-149
and the part number is PSK1JE05R00XAR

Here is the link for my model: Toshiba Laptop Support Homepage - Toshiba

Its from this page that i got the update for my sound card driver.
Thanks for your reply!

I notice there is a "Value Added Package" download, whatever that is. Maybe that includes the extra sound enhancements ???

If not, I would sent a query to Toshiba support about it.

Not the same problem, but related: Recently the music from my computer has been sounding terrible - muffled and booming bass with no clarity, no matter how I adjust my home stereo setting. Maybe this was only since I installed Windows 10, but I suspect a little before that. Anyway, I just found this tab and after unchecking Audio Enhancer and Surround Sound, it suddenly sounds amazing! It's terrible having a dubious "enhancement" like this hidden away so deep in the sound properties.
