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

Sounds very interesting, and if it isn't too complicated I would certainly try to use it. Saves me burning discs.

Hi there,

just a short note to gauge the interest, or the lack of, in the following idea:

There are currently several solution for playing SACD (and DVD-A) ISOs, on both Windows and Linux, but neither of this operating systems allow DSD to be transmitted over HDMI - as SACD players do.

This means that millions of native DSD capable, multi-channel DACs already in people's homes (called "Home Theatre Receivers" / AVRs), cannot be used for native DSD playback. Instead, a surround sound DSD enthusiast needs to spend a lot of $$$ for something he/she already has - just with a different kind of connector on it (USB instead of HDMI). (1)

On Windows, drivers for all HDMI capable cards (Intel, Nvidia, AMD) are closed source, so this is a non-started.

On Linux, I spent several weeks doing gap analysis, and I am now reasonably confident that it can be done. (2)

The end result would be that you could replace your SACD player completely, and play SACD ISOs from the hard disk, over HDMI as DSD, and to your receiver. (3)

So before I take this any further, I would want to know - do you guys think this is a good idea, and would use it?

Thanks

Footnotes:

(1) And that is assuming there are any desirable multi-channel DSD DACs to buy, which I'm not entirely convinced of.

(2) On Linux, there are currently only two apps that play SACD ISO (Jriver and MPD) but I would think that this should not be a significant reason for concern?

(3) Perhaps you do not cherish the idea of fiddling with Linux, but would be happy to use a packaged solution/appliance, that you can control with a remote app?
