Is that good enough to got non lossy audio and have have proper Dolby Digital 5.1? Will it help if I run an optical cable from the TV to the receiver alongside the HDMI?
Yes you will get 5.1, and if you have a BD player Dolby TrueHD.
The Onkyo HT-S3400 is an great system, I have it.
As Ratman says, your Samsung does not suport ARC. The way you have it now is fine.
You can hook up an optical cable from the TV to the receiver for OTA broadcasts, or even for gaming like a Wii. Thats what I did.
My Onkyo is paired with my Panny 42" LCD which supports ARC. However there is a little glitch with it. With my RIHD link on and ARC enabled on the Onkyo on at the same time, the volume cuts out everytime I try to raise or lower the volume on the receiver. If I turn off RIHD link, the problem goes away, so I have a feeling it has to do with the Viera link path and the ARC path conflicting whith each other at the same time. So I just leave ARC off, and use an optical cable from the TV to the receiver.
