I recently picked up an RME HDSP MADI card to test it as a playback
source for a digital mixing console. For testing purposes, I loaded it
onto a VIA epia board (yes, you read that right, 600 MHz, baby!) and
installed the recently released DeMuDi 1.2. When DeMuDi loads, the
first thing I do is modprobe snd-hdpsm. Then I can start jackvia
qjackqtl and it shows 64 record channels and 64 playback channels.
Success!! kinda....
Now I'm stuck. I can't figure out how to change the mixer settings.
I've studied all the info at the ALSA site and on Winfried Ritsch's
site but I'm too much of a noob to know what it means.
hdspmixer apparently does not support this card yet. It says:
Card 0 : RME HDSP MADI at 0xde000000, irq 10
No Hammerfall DSP card found
alsamixer seems to have no effect (?) I think the playback channels are
not routed to the outputs.
Winfried has some example apps that use the hwdep-interface to set
mixer values but the .tgz file seems to be corrupt. using tar -xvf or
-xvf it reports the file is not in gzip format.
Questions:
How do I set up the card so that Jack can read/write all 64 inputs and
outputs, with no attenuation in the card's mixer?
Does anybody have a valid hwdep-interface example for this card? (I am
trying to contact Winfried but I'm not sure I have a valid email
address for him)
Thanks for any help,

I suspect that this card is indeed not supported by hdspmixer at this
time and would likely require some work by Thomas Charbonnel. You
couldn't be in better hands when he gets going.
In the meantime, if this card is accurately supported by the driver
you've loaded (it may not be...) then you could try some set of amixer
commands to attempt to set levels and routing.
If you're early experiences are anything like my HDSP 9652 experiences a
year ago then I would suggest trying to record before you try playing
back. The reason for this is that input channels either do or don't make
it in and you can more quickly tell if the amixer commands are
performing as you wish. On the output side you have to not only set
levels, but you also have to set routing. That makes getting output from
the RME cards more difficult than getting input.
Once you can correctly record you may (or may not) have enough info to
get the output side going.
Good luck! (You're gonna need it!) ;-)
With best regards,

Have you tried alsamixer? It's a command line tool, but it's got a curses type
interface (IOW it's GUI)

If I understand the question, you have to pass the number of channels to jackd
when you fire it up.

alsamixer doesn't support the hdsp card line. Probably won't support the
MADI stuff either. Far too much complexity for that mixer.
