Re: [SurroundSound] Re: Any interest in PC playing DSD over HDMI?

Hi Robert,

Window is not a problem as such. Situation is more or less the same on Windows and Linux - Both operating system sound framework and HDMI drivers do not have DSD bitstreaming over HDMI implemented.

The reason I propose Linux to implement this, is that the source code for both components is available, so this functionality can be implemented by anyone with knowledge and time.

On Windows, theoretically, this can be implemented too, but the only parties that can be sure of success, are Microsoft and vendors that make HDMI device drivers (AMD, Nvidia, Intel) - as only they have the source code for it.

So yes, the "use non Windows software to perform this" is what I intend to do.

Andrej, this topic is very interesting.  Eventhough I'm happy with a DSD to PCM conversion for various reasons, I wouldn't mind expanding into a system that's capable of passing DSD directly to my DAC (Oppo 105) via HDMI.  I had no idea it was a Windows issue.  On the Oppo discussion thread, they state DSD cannot be passed through the Oppo's HDMI input.  I'm now wondering if it actually can if Windows allowed it (which you've made clear that it doesn't and probably never will).  Oppo's A-synchronous USB input does allow DSD - but only two channel.  This is the surround forum and I love multichannel audio, so I'm really hoping Oppo's next player will allow multichannel DSD through it's A-synch USB input.  

 

Oppo's regular USB input (in which you connect a mass storage device) can handle stereo and multichannel DSD files.  But as you nailed it on the head, the interface leaves a lot to be desired.  I hate it.  UPNP/DLNA can also pass DSD (stereo and multichannel), but is an absolute headache for those of us who like to keep the ISO format and not extract to DSF/DFF.  This is why I stick to using Foobar and having it convert to PCM and then pass to my Oppo via HDMI.  

 

The Exasound is the only DAC I'm aware of that can handle stereo and multichannel DSD files through it's USB from the computer.  At $3,800, it's just not worth it to me.

 

I'm very interested in your solutions.  But I don't know anything about Linux and not about to take the time to learn and build a separate Linux computer.  I'm confused about your all-in-one box solution.  Is it a separate device that will connect to my Windows computer via USB or other interface?  Or is it a standalone unit - where I need to connect a monitor, keyboard, and mouse to it directly?  A big concern would be it's interface.  I've spent quite some time learning to use and customize Foobar.  I've gotten just the way I want it.  Some people prefer JRiver or XBMC.  Can the interface in your one-box solution keep everyone happy???  I guess we need more details.

 

And lastly, thanks for all your efforts into this hobby!
