I just purchased a Panasonic Viera Plasma TV model TC-P42S30. Since it has
no analog audio out for my legacy stereo, I purchased a FiiO Optical to
Audio Converter Model D3,
http://www.fiio.com.cn/product/index.aspx?ID=33&MenuID=020302 .But when I
hooked it up to the TV digital optical out, all I got was a pulsing sound
from my stereo.. The digital to analog converter worked fine on when
connected to the digital optical on the Blu-Ray but not on the Panasonic TV.

I took the converter to the store where I purchased the TV and the sales rep
connected it to a Panasonic TV and got the same results. Is this converter
not able to decode the digital signal from Panasonic TVs? Can anyone
recommend one that will work with my TV?

A related issue...

Though it's not the source of your problem, you might want to look into the
possibility of ground loops, especially if you wind up making an analog
connection between the Panasonic and your system.

It's difficult to find RF isolation transformers for cable systems. MCM
sells one -- the #33-8700 that seems to work okay. It's sometimes available
for ~ $10. You might also want or need a double-F connector, #33-480.

Nope. With TVs you have to use this:

I think that will do it. When RTFM (thanks spamtrap1888) the Panasonic will
provide Dolby Digital when an ATSC channel is selected and PCM when NTSC
channel is selected. I'm getting ATSC over the air so I need to convert
Dolby Digital. Looks like the Gefen unit will do this. I'll get it and
post back the results. BTW, I could find no menu option to change the
digital optical out fomat on the TV. Thanks to all for your help.

Yep. That did it. The Gefen DAC successfully converts the Panasonic
Optical Digital output Dolby Digital to 2 channel audio. Yippee!

This digital stuff is all new to me.

Thanks all,
