Subject: [linux-audio-user] RME hammerfall DSP Multiface: help needed

I'm having a hard time bringing my new RME pci interface and Multiface
to run... and would appreciate some help ;-)
I'm working on Debian/unstable, have compiled the kernel with lowlat and
preempt, installed ALSA, inserted the hdsp modul, made a basic ~/.asoundrc,
compiled hdsploader from alsa-tools and with the friendly help of Thomas
Charbonnel also hdspmixer.
hdsploader loads the firmware (well it does the *second* time I run it,
which is a known problem, as Thomas told me). The error LED on the
Multiface is off. Input (on analog input1) *does* show in hdspmixer
(only in the *input* channel, nowhere else), but I can't get any sound.
Hmm, here I have the first question: Do I have to run alsamixer or
hdspmixer or both to unmute the channels? (I have tried all of this).
I have tried to feed a signal to analog input 1 and get it out from
analog output 1. I have also tried to set the internal routing with
amixer, but don't know if I have done that right... Well, the doc
says hdsp defaults to route inputx to outputx anyway. But I can't
hear anything...
I have tried 'cat some.wav > /dev/dsp' no sound, no errors.
(where would the error message show up?)
I do hear a high pitched hiss on line out, nothing else.
Please tell me: What would be the most basic procedure that should
produce sound output on the Multiface?
What diagnostic information can I give you to find out why it is
not running yet?
Thanks a lot for any hints!
