Cant Get Sound from SPDIF Optical Output

I have an Abit IP35 motherboard with built-in SPDIF optical output, and a Technics SA-DX940 decoder/amplifier (which can decode DTS and DD) that i want to use with my PC. I have conencted my amplifier to my motherboard's spdif output with an optical toslink cable. (Note: I'm using Vista Ultimate 32bit SP1, motherboard has Realtek ALC888 sound chip and ive got the latest drivers).
I have also set the digital output as default sound device.

Now when i goto Control Panel and Sound Properties and press 'Test' button i hear no sound and my amplifier shows no sign of its getting any signal.
BTW; I can see the red light at the end of optical cable... Also, my amplifier shows a DTS or a DD logo when its operating normally and getting a digital signal.
But when I Test thru my PC, it shows nothing and produces no sound. This is also same for DVD and .mkv with surround sound playback from my PC.

How can I get SPDIF output to work???

How should you connect your CD player to your av amp (both Technics) using an fibre optical cable?


It sounds like your CD player does not have an optical audio output. If so, you will need to get a "Digital to Analog Audio Converter". You can find them on eBay or Amazon for as little as $10. Connect your CD player's analog/RCA-style stereo cables to the converter.Then connect the converter to your receiver with a single optical cable. 6_20_2016_11_27_39_am.png

Yamaha RX-V595 Receiver will play Dolby Digital 3/2.1 audio Blu-Ray disc with player set to bitstream but will not play DTS-HD 3/2.1 unless output is set to PCM. Is this an issue with the Yamaha Recei


The optical connection (SPDIF) doesn't have enough bandwidth to transfer DTS-HD audio. To use DTS-HD, you must connect the blue-ray player and receiver via HDMI cable.

Each DTS-HD audio track on blue-ray includes also "normal" DTS audio, which is probably used when you select PCM. Player decodes it and sends decoded (non-HD) audio via optical cable to receiver.

HOW CAN I CONNECT A MIXER TO A TECHNICS SA-DX940 AV


I used the manual downloaded from http://www.manuals365.com/technics/sadx940.html

Try using the final stereo output of the mixer as the input to the CD or Tape or VCR inputs.and use the switches on the fromt of the DX940 as necessary.
The specificatios state input sensitivity is 27 mY so your mixer needs a low output..
No reason it shouldn't work.

Didn't supporting DTS when playing DTS filims no sound is hearing i would like to make DTS support on my dvd philips any codecs for that or any other way?


Maybe your player,simply does not decode dts streams.
All you need to do is to buy a decent receiver with digital inputs.Connect player to receiver using an optical or coaxial cable[or hdmi 1.3/1.4 cable] and let the receiver do the dts decoding......
Don't forget:sett the audio output in your player to "bitstream".

Technics SA-DX940 Digital optical audio input


When you say you have sound from the BD prior to disc load... where (TV and/or receiver)? Initial wake-up audio is usually 2-channel.

Describe the optical audio connection input to the receiver and any other audio paths that are attached.

Do you have other multichannel sources you could use to test this, like a cable TV box?

There's an obscure setting in the receiver called PCM Fix (on Page 21). Give that a look.

What kind of optical or coaxial cable do i need to get exces to dts and dolby digital


To get DTS and Dolby Digital sound you will need one of a few types of digital cable to connect the digital output on a device to a digital decoder or receiver. One type of digital cable is the SPDIF Coaxial, which is a single cable that can transmit high quality digital audio. Another cable for digital sound is the Toslink Optical cable which uses plastic or glass fibres depending on the cost to transmit light which is then decoded into sound information. With optical cables the signal can break if the cables are bent too much. The other cable that can be used is the HDMI cable, this is used to stream HD video and HD sound formats such as DTS HD Master Audio and Dolby True HD, these can of course stream the standard Dolby Digital and DTS signals, but for what it is worth I would recomend a SPDIF Coaxial cable. These can be found at hi-fi shops and places such as Maplins or Ebay. They are also cheaper than the other digital cables and more reliable than optical ones. Any type will do as long as you have a decoder or home receiver which can convert the digital information into sound. Infact you can use an RCA composite cable and connect that into the coaxial ports at either end. This will transmit the digital information, but not as good quality as a proper coaxial cable, but you still get the DTS and Dolby Digital formats with full surround sound. I hope that this helps.

Digital optical output for technics 5.1 surround sound receiver


I went to the HDTV plasma manual. It stated the only way the digital optical audio output would work (from this TV) was to go to the menu, select audio and turn off the TV speakers. Basically, it had nothing to do with the technics receiver.
