Foxsat-HDR and Digital Audio
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.

You need digital audio from HDR to the receiver, the TV gets a stereo downmix.
There is an optical digital audio out so use that. |

Digital Out
Hi
![]() As already stated there is a optical link from HDR which I use to plug into my sound system. However I have found that it only feeds the digital output on BBC HD ![]() If you press "I" on remote control when watching BBC HD digital out icon is there on any other channel the icon does not appear. In practical tests the only time I see a signal and get sound via my 5.1 (AC3) decoder is on BBC HD. ![]() Can anyone else confirm if this the case ![]() Cynderyn |

I have one similar to that for the Humax and PC, be aware though that you cant turn off the Humax optical so if you are listening to another opitcal input and the Humax powers up to record. It will stop the audio from the other device.
Ive put this in the bugs thread as its very annoying if you are using a different input and have to unplug the Humax optical. BBC is the only channel that has 5.1 sound and it only has that intermittently, you may get lucky with ITV HD or you might have to wait weeks to get 5.1 on ITV. Try Lux HD if you want to test 5.1, this is in non freesat mode. |

Hi,
I experienced the same 'problem'. I have HDR connected through S/PDIF to receiver and Dolby Digital 2.0 or 5.1 when applicable. However only a stereo signal is provided from HDR->[HDMI]->TV->[S/PDIF]->Receiver. This is truly a shame as otherwise I could save myself an S/PDIF port on my receiver, and also save having to switch my receiver from TV input to HDR input. the HDMI cable is able to transport Dolby Digital, so why downgrade? That does not make sense to me and sounds like a bug. Wouter. |

It's the TV that is downgrading - better ask your TV manufacturer...

Only one input can be routed to the output, being mechanical the optical input routed to the output can only be changed by operating the switch. How can the Humax input interfere with the other ? |

Now its no problem switching the PC optical off for the Humax to work but you cant have the Humax recording while using the PC optical. The digital off does not work in the Humax menu. |

Thats true, my TV to surround is 2.0 but the Humax direct to the surround system is 5.1
My adapter isnt a manual switch, you have to switch the other device off to make it work. Now its no problem switching the PC optical off for the Humax to work but you cant have the Humax recording while using the PC optical. The digital off does not work in the Humax menu. |

That would be horrible if that is the case. I have one of the latest Sony TVs (W4500), fully supporting dolby digital etc.

Why not replace it with a manual switch in this case it would surely be more convenient to have a manual switch rather than having to disconnect the toslink lead
Saves plugging and unplugging every time I want to use a different device. |

Have you actually tried to see if DD5.1 comes out of the optical output when it's being input on the HDMI. I ask because the manual for my KDL-40W4000 is very vague in this respect and to play 5.1 on the tv's speakers obviously has to be downsampled to stereo. As a result suspect that DD2.0 rather than 5.1 might be output.

phew!!! Confusion reigns here
Wonder if setting a modern TV and reciever up will become a degree coarse sometime soon ![]() I have the very latest Sony TV (40Z4500). Now I suspect that because it has a TOS output for sound that it's capable of routing DD 5.1 from a peripheral (in this case the Humax HDR) HDMI cable through to the sound system. In my case this appears not to happen. I have since discovered that not all HDMI cables are the same, arghhhh! Apparently you need a HDMI cable that is 1.3a, 1.3b, 1.3b1 or 1.3c? As there is nothing on the HDMI cable (supplied with the Humax) to tell me what it is I would have assumed that it was capable of DD5.1 http://en.wikipedia.org/wiki/High-De...edia_Interface OMG! and I thought computers were difficult enough ![]() Alan |

Since both the Foxsat HDR and the W4500 as well as the Z4500 support HDMI 1.3a+ I would also have expected for the Dolby 5.1 to be carried forward. I will look in the TV manual to see if there is any info. |

It doesnt say what the HDMI cable it, Ive seen here you need a 1.3 for it to communicate with the TV to synch off and on but I have no way of finding out if its the cable thats the problem.

Can't remember if PCM can be converted to DD5.1? |
