Adrian, Takashi: I added you to cc, as you last touched this code,
sorry if I should have cc'ed someone else. It appears that the HDSPM
module does not recognise cards with firmware revision 0xCC:

Ah, I see. Thanks for the clarification. This means that the kernel is
not able to recognise your card. Pre-.39 it would load anyway, but
since .39 it gives the warning you posted and refuses to load. Your
firmware revision is 0xCC, which is not recognised. If your card is
MADI, the kernel expects the firmware revision to be 0xD2 (or starting
in 3.0, it also accepts 0xCF).

I guess this can be fixed easily by adding your firmware revision to
the list of accepted revs.

Adrian: is any more info needed to add this rev?

Cheers,

Tom

I have cards with CC and CF, and maybe also D2 (haven't checked them
all).

Exactly.

I hope so, too. Please try the attached patch.


JFTR: You need at least ALSA-1.0.24 userland (or the corresponding
hdspm.h respectively) for the new driver (2.6.39 and above). Likewise,
if you intend to use hdspmixer, you need the yet unreleased 1.0.24.2
version of alsa-tools, so go for the git version:

   http://git.alsa-project.org/?p=alsa-tools.git

Fons (or anyone else who could reproduce the problem),

If you want to try out Adrian's patch, I uploaded a kernel with the
patch applied here:
<https://dev.archlinux.org/~tomegun/kernel26-2.6.39.1.3-1.1-i686.pkg.tar.xz>.

Cheers,

Wow ! I'll have (hope to have) 5 machines to test it tomorrow !

Thanks for providing this !

Installed on two machines so far, more tomorrow.
Seems to have solved the problem :-) :-)

An unrelated question: I see references to the RME Raydat
interface. Does that mean it's supported ? Also with period
sizes < 1024 ?

Good to know. I'll wait for your final confirmation and then commit it.

It is. It's actually the card I'm developing on. So far, all period
sizes from 64 to 8k (iirc) work. I don't know if 32 is supposed to work,
at least on my machine, it doesn't.

One problem: the gain settings have changed, now having a range of 0..64.
How do these values map to the internal ones (0..0xffff) ? I *hope* there
is value corresponding to EXACTLY 0x8000 (gain = 1) !!! The reason is
that MADI is bit-exact and is used to tranport other values than just
audio samples. This works of course only with exact unity gain.

BTW, why was this change made ? For pro users (are there other of this
card) this is a regression.

For the simple ALSA mixer, the driver does

   gain = ucontrol->value.integer.value[0]*UNITY_GAIN/64;

UNITY_GAIN is 32768 (0x8000), so if you select 64 on the ALSA side, it
gives you exactly what you need. Or in other words: faders to 100% in
alsamixer, that's it.

With hdspmixer or any other software that's using the full mixer, you
can still use the fine-grained 65k steps.


> BTW, why was this change made?

No idea. I reckon faberman was tired of stepping through 65k mixer
levels in alsamixer. ;) (disclaimer: I never used the old driver, so I
don't know how it was before)

More news, not all good. After trying out all combinations and doing it
again to be sure it seems that:

* kernel26-2.6.39.1.3-1.1-i686.pkg.tar.xz and its hdspm driver work well
on the five machines that have cards with firmware revision CC.

* With newer cards (they arrived just two weeks ago) with revision CF
things seem to work but there are crackles in the sound - not loud but
clear enough. Sounds like single samples being modified every now and
then.

    - Older cards on the same machine with the same kernel work fine.
    - Kernel 2.6.37 on the same machine with the new cards works fine
      as well.

So there must have been some regression.

For now I have to revert two machines (those using the new cards) to
2.6.37.
