[linux-audio-user] help needed with RME MADI card

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, Ben Loftis
