I have the new Humax HDR and am really pleased with it. However, I'm not sure how to set up my system to receive Dolby Digital thru my home cinema system.

I have the HDMI cable linked to my TV (Sony Z4500) and a TOS (digital optical) cable from TV to my home cinema system (Sony HT-SL40) but when I set the home cinema to auto detect all I get is stereo thru my front speakers even when viewing HD programs. I can of course manually switch to Dolby PL/PL11-MOV/PL11-MUS but I'm sure the amplifier should auto-detect this and I'm not sure whether I'm getting the best from my system.

I notice with the Humax spec tho that it states Digital Audio Output is thru the S/PDIF socket (Whatever that is!) but my amp does not have a corresponding input for S/PDIF.

Am totally confused!

Any help would be appreciated.

BTW, the reason I run the Optical cable from the TV (instead of the Humax which suprisingly does not have an TOS output!) is because I have Freeview built into the TV which I watch quite a lot of the time when there is no HD worth watching.

erm...the humax does have a toslink optical output. It is next to the hdmi socket.

SPDIF is the data format and physical connection spec as designed by sony/phillips to carry digital audio donkeys yearsago.

It can be carried by toslink (optical ) or 75ohm electrical (coax RCA connector)

see here

http://en.wikipedia.org/wiki/SPDIF

The foxsat does output 5.1 Dolby Digital over the HDMI cable BUT your TV may not then relay that over its optical output.

To check this out simply remove the optical output from your tv and connect the amp to the foxsat instead. Tune to BBChd during the preview loop. This loop is in 5.1 DD.

The amp should start playing DD 5.1.

Basically you need to plug your TV into one optical input on your amp and the foxsat into a second input.

Yes, also as someone in the other thread states the foxsat may only decide to send a stereo downmix to the TV.

Although it is capable of DD over HDMI (as I use it) I am not sure what it does when connected to a device incapable of using that type of signal...ie some (maybe many) TVs.

However advice still the same, you need to plug your TV into one optical input on your amp and the foxsat into a second input.

Theoretically it is good practice to feed everything (Sky, Freeview, freesat etc. into the amp and then you only need one feed (usually HDMI) into the TV.

I hasten to add, your mileage may vary.
