Can anyone help me with this series of electrical connections?

I have a TV, set-top box for Freeview, and a (new) blu-ray player.

TV sound is off, and the set-top box is linked to my sound equipment.

What I would like is for both my set-top box AND my blu-ray player to play out to my sound system.

At the moment, for blu-ray, I have to switch on the TV sound, and then listen to the sound through the TV's tinny speakers.

All the connectors involved are illustrated here:

Thanks for any help.

Sounds as if you need a separate audio cable from the blu-ray to the sound system. Which type will depend what inputs the sound system has.

^ It's an old sound system using a red and a white jack for right and for left audio. To follow your suggestion, I think I would need an optical out connector from the blu-ray, split in to a left and a right jack.

I was hoping that both TV and blu-ray might operate via the set-top box, and I see the set-top box has a SCART connection for 'DVD'; but the blu-ray has no SCART connector.

Looks from the picture as if the blu ray has audio out L/R as phono plug sockets. Sounds as if you just need a couple of cables. One red, one white from blu ray to amp. Even if you use an hdmi switch, you'll still need the separate audio leads, and I don't think you can get the switches with audio out.

You can get a scart connector with yellow, red and white jack. You then need an audio cable red&white and another one for the video. If you already have your player connected to your TV with hdmi, then you don't need the cable for the video.

What connectors does the sound equipment have? Also how is the sound equipment connected to the TV? You need to create a sort of "loop" connection to allow the use of the BR drive to go through the speakers and still display the picture to the TV without using the TVs sound. 


We have a pioneer surround system (5.1) and that has a scart cable going to the sky box and a HDMI cable going to the TV. We have to press the "line" button on the remote to switch the speaker sound from TV (freeview), sky and the dvd player itself which is part of the speaker system. You can do the entire thing through scart lead, but you'll often lose 5.1 surround on TV sources such as sky and freeview unless the content supports it and you use an optical lead instead.

Thanks for the ideas. I'll need to get my brain around all of this.

I'm using HDMI connectors to the TV, from both the set-top box and from the blu-ray.

Connecting directly from blu-ray to sound system (via red / white phonos) does not work, I think because the sound goes to the television via the HDMI connection. The remote control volume on the blu-ray does not operate, showing that the HDMI connection is carrying the sound away with it. It's the blu-ray I need to set up, and that does not have SCART.

I see there are a lot of Internet references for stop audio going with HDMI, so I'll do some fishing there.

Just a thought, but there isn't an option to turn on the audio output in the setup menu for the blu ray somewhere is there?


Otherwise as already suggested a scart adapter to audio out (then connect that to the sound system) on the back of the TV. Watch those things though, the cheap ones are nasty and can give you ghosing on the video.

Yup, I think a little more flounder ought to do it! (I have no clue what you guys are talking about!! Topics like these are why I have two sons.)

Ted, I hate to tell you this, and it may be a bit late in the day, but I think you should know that topics like these are not why you have two sons!

I don't think the TV and SCART will come into it, Dave. I'm looking at connecting the blu-ray to the sound system - no SCART connections there. And no possibility to connect from blu-ray using SCART.

The problem seems to be the HDMI connection from blu-ray to TV. There is no SCART get-around for that, I don't think, unless -as Ted suggests - I'm floundering.

These are the complete set of options for setting the audio on the blu-ray. The answer may be there but, if it is, I can't see it:

Audio (HDMI)

Auto: Normally select this. Outputs audio signals according to the status of the connected HDMI device.

PCM: Outputs PCM signals from the HDMI OUT jack.

DSD Output Mode

On: Outputs DSD signals from the HDMI OUT jack when playing a Super Audio CD. When [on] is selected, no signal is output from other jacks.

Off: Outputs PCM signals from the HDMI OUT jack when playing a Super Audio CD.

BD Audio MIX Setting

On: Outputs the audio obtained by mixing the interactive and secondary audio to the primary audio.

Off: Outputs the primary audio only.

Select this to output HD audio signals to an AV amplifier (receiver).

Dolby Digital / DTS

Downmix PCM: Converts to output Linear PCM signals. Select this when connecting an audio device without a built-in Dolby Digital/DTS decoder.

Bitstream: Select this when connecting an audio device with a built-in Dolby Digital/DTS decoder.

DTS Neo:6

Cinema: Outputs the simulated multichannel sound from 2 channel sources via the HDMI OUT jack according to the capability of the connected device using [dts Neo:6 Cinema] mode.

Music: Outputs the simulated multichannel sound from 2 channel sources via the HDMI OUT jack according to the capability of the connected device using [dts Neo:6 Music] mode.

Off: Outputs the sound with its original number of channels via the HDMI OUT jack.

Audio DRC

Auto: Performs playback at the dynamic range specified by the disc (BDROM only). Other discs are played back at the [on] level.

On: Performs playback at a standard compression level.

Off: No compression works. A more dynamic sound is produced.

Downmix

Surround: Outputs audio signals with surround effects. Select this when
connecting an audio device that supports Dolby Surround (Pro Logic) or DTS Neo:6.

Stereo: Outputs audio signals without surround effects. Select this when connecting an audio device that does not support Dolby Surround (Pro
Logic) or DTS Neo:6.

If you think about it, there isn't much point in having the audio outputs if they don't work when there's an HDMI cable plugged into the unit. I'd try the different settings.

^ Looks great, that's my after-supper looked after!

ETA: Softly, softly catchee monkey. I've managed to get the sound from a CD through the blu-ray and amp combination, simply by reacquainting myself with the details of the amp. No joy with sound from a video DVD, as yet.

I'm hoping Sony will help me out here. Possibly a digital-to-analogue converter will take sound from the (blu-ray) optical audio connecter to the analogue amp? I just need to be sure that this will cut out the sound going out from the blu-ray on the HDMI connecter.

What about the headphone output from the telly? Or do you want ot be able to use the telly speakers sometimes?

Good thought. The output from TV via headphones is very good, particularly when compared to the tinny speakers on the TV itself. Both audio CD and video dvd audio come out from this channel, and the sound is moderated by the TV remote (but not by the blu-ray remote).

Not sure if this will end up disclosing a method for using the analogue amp plus external speakers, but it certainly gives a method for enjoying the blu-ray player!

Get a 3.5mm (I assume) stereo jack to RCA phono adapter off eBay. Connect headphone socket to the input on the amp. Should be absolutely fine. Very high impedance input on virtually any amplifier means that it won't allow more current to flow than needed. I've done it with lots of things. There is also lots about it on the net if you search something like "headphone jack on tv to amplifier" Lots of people have the same problem as you.

How about this:
http://www.amazon.com/Extractor-Digital-Converter-De-Embedder-Decoder/dp/B005COKXCO
"This HDMI Audio Extractor is a device that allows you to extract audio signals from your HDMI source. When connecting your HDMI device to a TV or display you don't always get great audio from the TVs built in speakers, or in the case of a display only, no audio at all. With this Audio Extractor you can take your original HDMI audio signal and convert it to optical or analog L/R audio."

Sounds like great advice, thank you both.

I looked at several threads about trying to separate the sound from an HDMI stream, but didn't find those components for sale. They would involve, I suppose, two hdmi cables, one to take the signal to the adapter / splitter, and one to take it away. Dave's method may be more straightforward. I've just ordered a cable lead that should be good to experiment with.

Thanks again.
