Title: Motherboard without audio or SPDIF, need digital output
Post by: Barbapapa on January 23, 2014, 05:57:36 am
I'm building a workstation using a server MB that doesn't have any audio provisions or SPDIF. It's an Asrock H87WS-DL http://www.asrockrack.com/general/productdetail.asp?Model=H87WS-DL (http://www.asrockrack.com/general/productdetail.asp?Model=H87WS-DL)
I need to send a digital signal to my Onkyo TX-NR900.

Did I make a mistake in not choosing the MB that has SPDIF and audio? I could exchange it for one that does or is there a better solution anyway?

The version with the audio is H87WSA-DLhttp://www.asrockrack.com/general/productdetail.asp?Model=H87WSA-DL (http://www.asrockrack.com/general/productdetail.asp?Model=H87WSA-DL)

My goal is high quality stereo music only, no multi stuff for movies etc.

So this is the beast you've got for driving your audio, huh?

You could pick up a USB DAC as one option but if you can exchange the server MoBo for a board with SPDIF out, then that would cut out the middleman. I'm a minimalist myself (Occam's razor has worked pretty well for me so far). I'm sure there are others out there with sharper minds that might see a sensible and cost effective work around. I'm just a simple user.

For my set up, digital audio/video travels out of the MoBo via HDMI and into my amp. The amp then splits the audio and feeds it into the amp/DAC and passes the video through and on to the monitor / TV. Minimal handling and the audio stays in the digital domain for pre-amp and amp'ing. Ehhh, who cares? It's the sound that matters and works for me.

All the best with getting your rig set up to pump your fave tunes.

Yes, all that for enjoying my music. I assume the Onkyo's DAC is good and the thing to do is deliver digital signal to it.

Using SPDIF on a MB would be simple but I have this nagging feeling that the 'middleman' of a USB converter might have some kind of audio advantage I'm too ignorant to understand.

Thank you!

I'd get a DAC (though I'm not the right person to advise "which" DAC but there are a few threads on this board) as it could be more flexible than SPDIF pending the number of channels/format you may want.  Like all technologies, I'm sure the quality of DACs have improved over the years (and the price come down) compared to the Onkyo

Good point - S/PDIF is a little dated and has its shortcomings:
http://en.wikipedia.org/?title=S/PDIF#Hardware_specifications (http://en.wikipedia.org/?title=S/PDIF#Hardware_specifications)
http://en.wikipedia.org/?title=S/PDIF#Limitations (http://en.wikipedia.org/?title=S/PDIF#Limitations)
but according to this:
My goal is high quality stereo music only, no multi stuff for movies etc.
2 channels is fine, so S/PDIF is acceptable on that score.

Plenty of ways to skin the cat.

I'm surprised to hear SPDIF is lacking, is it the clocking that's a concern?
In my case I'd use something like an M2Tech Hiface which I assume handles clocking.

BTW, there are no MBs like mine but with SPDIF in stock after all.

It is only "lacking" in that it can only carry up to 2ch of PCM, or DTS/DD.  So no 5.1 PCM, DTS-HD, Tru-HD etc etc.

You can use a USB to SPDIF converter. Asus (http://www.newegg.com/Product/Product.aspx?Item=N82E16829132022) makes one that is $30 after the mail in rebate at newegg. The prices on a USB converters range from about $30 to $5000!

Bel Canto Design is just down (or up  :)) the street from JRiver in Minneapolis. They carry USB to SPDIF converters (http://www.belcantodesign.com/Belcanto_eOneSeries.html) for the audiophile with the cheapest being the MLink which you can find for $188 (http://www.dedicatedaudio.com/inc/sdetail/23604/34738).

There are lots of other ones including pro audio audio devices that also have SPDIF output.

That must explain why audiophiles seem to use USB-SPDIF converters a lot.

Thanks for that. It's comparable to the m2tech in price, not being a one piece thing poking out of a USB port is nice.

Interest piqued, I found this:

Reads reasonably to me. Maybe it will be of some help.

Why not a Behringer UCA202 with toslink? No drivers needed, plug and play.....

Or the HiFimeDIY Sabre USB DAC, also no drivers needed.....

Some usb dacs like the EMU 0404 are said to have great sound qualities but are plaqued by driver issues that really ruins what could be a great product. The usb interface seems like a crap shoot, at least with that one.

Does a usb port used as an audio out need all the conductors or could some of them be cut for a more reliable output to the external converter?

That seems like a good unit that's really underpriced from it's initial retail price for some reason. Thank you.

Let me answer my own silly question from 2 posts up: USB uses back and forth communication so no elimination unused connectors is going to help ::). Maybe using usb devices that aren't well known to cause conflicts might be a better approach. :)

I've been listening with my new VLink-192 and am happy. I now have a stable 'puter with sound being handled by usb and the music sounds great!

Glad you like it.  It's a great little box.
