support for RME HDSPe RayDAT

support for RME HDSPe RayDAT

[Matthijs ten Berge]

Hello all,

<intro:>
As you might already know, RME has released a successor for the HDSP
9652, the HDSPe RayDAT
(http://www.rme-audio.de/en_products_hdspe_raydat.php). It is based on
the 9652's design, with some new/changed features (e.g. more channels
and lower latencies), but the most important hardware change is that it
is now a PCI-express card.

I'm currently in the process of choosing which audio interface to buy,
the 'old' HDSP 9652 or the new RayDAT (I haven't found any other card
with 3 or more ADAT in/outs in the same price range or below, but
suggestions are welcome).
Of course I can stay on the safe side and opt for the HDSP 9652, which
has stable and complete driver support (right, eh?).
But on the other hand the RayDAT has better features and future, but
without the guarantee that it is or will be supported it can only serve
as a very costly paper weight (and not even a good one I suppose).

I wrote an e-mail to RME, but a bit too early, the card was not released
at that moment. See below for their reply.

<question:>
Are there any plans to add support for the RME RayDAT to the HDSP
driver/tools? Or perhaps somebody is already working on it right now? It
is not mentioned in the Wiki matrix atm.
I wish I could just do it myself, but (concerning kernel programming) I
never did more than a 'hello world' kernel module, so I don't think this
would be a good idea... (I do have coding experience, but not in-kernel).
>From the mailings on this list I can see that it can sometimes take
quite a while to get a driver fully debugged, how are the experiences
with RME cards?

I am aware that my e-mail might appear to be a crude 'I want to order a
pizza asap, at what time will the delivery boy arrive?'-like question.
Please see it more like a generic inquiry on the status and likelyness
of things.


Thanks and cheers,

Matthijs ten Berge

The RayDAT is not yet released, and I'm afraid I can't say much about
the current status of ALSA development (if any).

This will certainly be the case as soon as the card is released.

Yes, and no, since it is not released yet and there is only a very 
limited numbers of prototypes.

Adopting the drivers to support the RayDAT shouldn't take long.

Ok, not being available yet explains a lot. Begin May, the card was
already listed as 'available' at Thomann, then halfway May they
mentioned 'delivery date 23rd of May', which made me conclude it is
available already. But today their delivery date is listed as the 8th of
July, so we'll have to wait a little longer...

I assume they didn't release the programmers documentation yet?

That's good to hear. (un)fortunately it renders most of my original post
superfluous ;-). Thanks for your quick reply.

The ADI8QS arrived one year late, so that's nothing. I'd rather have a 
100% stable device than the usual rubbish.

No, it will be available with the card. But pretty soon afterwards you 
can expect driver support, if it is not a completely different design 
(which was none of the cards so far, just small differences, since they 
are all based on their pretty stable FPGA design).
