Something NEW - HDMI to SPDIF Converter

post #1 of 17
Thread Starter 

HDMI can output 24/192 without a problem, this is something than NO motherboard spdif output can do or any usb that I know of...

 

Now-a-days many motherboards have a HDMI out, so how about using a HDMI to SPDIF converter instead of a USB to SPDIF converter?

 

After all HDMI is "made" for audio and video, unlike USB which has only been adapted to serve the needs for audio, but was made for keyboards, printers, cameras, etc.

 

Like this....HDMI in one side and video out for your computer monitor out the other side "Plus" 24/192 audio out for your Dac.

Hi Dynobot,

 

I was in your same situation looking for a HDMI to SPDIF converter, hopping to turn my portable media player with mini-HDMI out to be the ultimate audio transport. I found a "studio" grade HDMI to SPDIF converter like that in your picture, almost pulled the trigger, then remembered asking whether the SPDIF can preserver the DSD, Dolby 5.1, etc information. The seller said no and I realized the converter might not be bit perfect.

 

Does your coverter advertise as compatible with all the DSD, Dolby formats? If so I am very interested.

USD250 is approaching the price of media player with SPDIF out like the Squeeze box already. And it says it is only compatible with HDMI1.1

 

The one I found 2 months ago costed about USD60. Actually I was thinking of whether to buy the Audio-gd DI or the HDMI-SPDIF converter at that time.

 

BTW, it also seems that the Audio-gd isn't compatible with the DTS audio and Dolby Digital Format. I pressed the test signal button in Windows 7 and got no sound. So I am not sure whether that is important for the HDMI-SPDIF converter if it is for 2 channel audio purpose.

Hi. I rescue this old thread with a question about the HDMI to DVI-D Converter with SPDIF Digital Audio.

 

Have you already tried them? Would they work in a tablet with HDMI output, like the Ainol Novo8?

 

Now they sell HDMI to VGA + SPDIF converters Ebayon  for $44. Would they be bit-perfect for standard 44000 Hz 16 bit ?

Thanks for the link - I may have to give one of these a try as an alternative to my usb transport!

I was going to buy one of this HDMI to S/PDIF converters and one Android Tablet, to use it as my music source, but I have read at the specs of the tablets with HDMI output that the tablet screen will be off when HD video is playing. This makes me wonder a very important thing:

 

Will the Digital Audio through the tablet HDMI output work while you are playing only audio?  (FLAC files, no video and no external display connected to the HDMI)

 

If it doesn't, then Android tablets are absolutely useless for serious music playing, until Google solves the support for External USB DAC.

I naively posted something along those lines about 2 years ago over at Computer Audiophile, and it was pointed out that the HDMI standard was a camel - a horse designed by a committee - and that audio was a very poor second cousin to video in the design process. 

 

USB, like any other bus technology, is purely for data transfer - your comment about printers and cameras is less relevant than 'does USB2.x have the transfer speed I need for my DAC ?'. Proprietary drivers can be an issue, granted, but many modern DACs use the drivers provided by the operating system.  Read the list of 'Applications' HDMI was designed for .....

 

http://en.wikipedia.org/wiki/HDMI#Applications

 

Also, AFAIK, USB has no support for content protection - HDMI does:

Personally, I cant understand why a data transfer standard has to include something so intrusive, but I guess thats what happens when you ask a committee to design your horse. If the aforementioned gadget can bypass any such restrictions, so much the better. I'll leave the Sound Science guys to thrash out the issues around jitter rates over SPD/IF.

I've heard at the manuals of few Tablets that the screen of the tablet gets blank when the HDMI output is used.

 

If that is like this, the Tablet will become a useless blind brick if we use it only the S/PDIF output (connected to a DAC, with no viedo monitor). Anyone has experience with this?

i can only see this being of use in the case of the original 60gig ps3 which comes with the ability to play sacd's, i really couldnt get much more use out of this past that, i already use an m2tech hiface for spdif out to my dac, too little too late i guess

Can you achieve 24-bit output? The specs on Monoprice won't tell...

 

I want to connect a MacBook Air to the digital coaxial input of a Little Dot DAC_I, so I'm thinking:

 

Thuderbolt to HDMI cable -> Monoprice switch -> digital coaxial input of DAC_I

 

Thanks.

My Android 4.1.1 tablet can be set as HDMI out with tablet display.

So I wonder anyone succeded in Android phone/tablet -> HDMI out -> SPDIF -> DAC -> Headphone?

 

It will be an another solution for Android's USB DAC.
