Default 5.1 Sound from HDTV Box

I have an outdated Sony STR-DE435 Surround Sound Reciever with 5.1 Channel Analog Inputs (no optical input) and am getting a Sony KDF55WF655 RPTV (optical audio output) with a Comcast HDTV tuner (I don't know what connections this will have). Does anyone know if the Comcast tuner will have 5.1 channel analog outputs or am I going to have to upgrade my receiver too?

I can't tell you for sure, but I've never seen an HD receiver with the 5.1 audio outputs, only on DVD players.

For your TV , the Sony specifications shows the HDMI connection to enable "Analog audio":

I have never understood HDMI to carry other than uncompressed digital Video and Audio signals. I must be missing something here !

HDMI explained by Panasonic:

I doubt an analog audio connection to the a/v will carry the 5.1 tracks. Your HD STB will certainly have optical or coax digital audio outputs.

Yes it would be worthwhile to replace your a/v. Not only will you get digital inputs but with a quality receiver you will get good processing of sounds in different DSP programs. If you do get one, make sure to connect digital audio from the STB to the receiver and not from the TV's audio output. It appears the audio output from TV's with HDMI may carry DD2.0 only (could be this analog treatment they are alluding to with HDMI).

Thanks. I've decided to hold off buying the TV until I figure out what I want to do with the audio. I have a feeling I'm in the market for a new 5.1 receiver as well as a new HDTV. Any suggestions on 5.1 vs 6.1 vs 7.1?

I guess I don't understand why HDTVs don't have a HDMI output as well as a HDMI input. That way, the TV can manipulate the digital video and pass the digital audio through to the next component.

well, i suggest that 5.1 is the best deal you can get so far since there are very limited media that actually uses 6.1 or 7.1. When you do get a surround sound system, i recommend that you get something with DTS and a built in dvd player since they seem (to me) to be the easiest to set up and is very convenient to use.

I am too considering a new receiver, not so much because of surround as I got that but because of inputs, considering either the Onkyo SR602 or the Denon 2105 which both have 3 Component and 3+ Optical Inputs so I can pretty much hook up everything. Wanting to use the Monitor out so I just need one input on my TV thus still trying to figure which set would give me a better PQ in the "loop through" configuration. Both are in the ~400-500 USD range.

According to the specs I read, the Denon will switch component video with a bandwidth of 100mhz. The Onkyo says 50mhz. I'd go with the Denon.
