That's interesting about the surround sound. I remember my husband turning that on once and it made some of the backgrounds sounds so loud the dogs barked! I made him turn it off and I guess it's never gotten turned back on so we're not having that problem.
I also have hearing loss and wear hearing aids. When there is too much background its extemely hard for me to hear the dialog. I've just realized that I've had some problems hearing the TV in my sewing room. I may have to check the settings this evening. I might be able to do something about it.
