Hello everyone1
I'm very new to the world of digital audio. but I wonder; I can see 12
capture ports in JACK, of which only 8 should be analogue inputs. So the rest
must be digital? So here are my questions:
Which items in the alsamixer correspond to their volume/routing? I'd like to
route everything to PCM out. Is it possible to have all 8 analogue ins and the
digital inputs work at the same time without having to hassle the card and
ALSA?
Sorry, I'm sure, that these are really questions of a simpleton, but I can't
help it. :-)
Kindly yours
Julien

I have a delta66 which also has 12 ins and 10 outs. The ice 1712 is the
same on both.
i/o 1 - 8 are the ADC 1 - 8 and the PCM 1 - 8.
i/o 9 & 10 is the stereo s/pdif in and out
input 11 & 12 is the output of the internal digital mixer (AKA
Multi-mixer) which can be used as a no latency (almost) monitor mixer if
the user doesn't have an external unit.
In my case i/o 5-8 don't do anything (though the outputs can still be used
by the internal mixer).

Hi Len!
Thanks. So no problem using input 9/10 in parallel to the rest of them.
Do you have any idea, which ALSA mixer items really relate to those? Do you
actually set any volume on them?
Warm regards
Julien

Out of the box on power up all the levels are Off or at the lowest
setting. The levels have to be set before use. It is best to do a:
alsactl store <card #> <-f filename>
And then add:
alsactl restore <card #> <-f filename>
to your boot or login. If you are using text with more than one terminal
open you want to do it with your boot so it only gets done once not when
each terminal is opened. Ubuntu (and maybe others) saves alsa settings at
session end and restores them at session start. If you use all virtual
terminals there is no session though.
The s/pdif i/o can be used at the same time as the analogue i/os but, an
input from s/pdif will set the the clock of the the whole sound card. SO
if the s/pdif input is set to 44.1k then no matter what the D1010 is set
to the sample rate will be 44.1k So if jack tries to set the card to
something other than whatever the s/pdif is set to, it could be confusing.
So remember s/pdif input is always the master clock.
I use an ART USBDualTubePre as a pre for the s/pdif on my system as this
gives me 24bits in sync that the USB doesn't. (I use the the same box as a
USB i/o on my netbook)
