I figured I start a fresh post so people can find it easier.
Turn on your Sony TV and hit the "HOME" button.
Scroll down to "SETTINGS" ENTER
Scroll down to "SETUP" ENTER
Scroll all the way down to "PRODUCT SUPPORT" ENTER
Scroll to "CONTACT SONY" ENTER
On this screen you will find the website to go to and the model, serial number and software version (FIRMWARE).
The new software from the Sony website is ver.1.012 which fixes the sound dropping out. You only need to do this if your software is 1.011 or lower.
My Software ver was 1.009 and model is KDL-40R450A.
Write down the model number to enter on the Sony website and follow the instructions. Very simple to do. Just need an empty usb stick.
The website is
www.sony.com/tvsupport
On the right side of the web page see "Select a type of support" then select "Drivers & Software".
Then input your model number including the dash. Then click on go.
Select tab for "DRIVERS AND SOFTWARE"
Then click on "FIRMWARE" and click "DOWNLOAD"
Once you down load the software to your computer, open the folder and copy the contents to an empty usb stick. Follow the instructions from the website to upload to your TV.
