Hello everyone!
So I've got the e-mu 1212 soundcard working. it should have two
analogue ins
and two analogue outs and then S/PDIF I/O and ADAT - i.e. 8 channels in
and 8
channels out. That doesn't seem to be the case.
12 and 12 at 48000 or 44100s/s.
With a normal JACK call to hw:4 I get 2 ins, 2 outs
(I suppose the
analogue
part.
With JACK using the syntax given in
Kernel/Documentation/sound/alsa/emu10k1-jack.txt
using hw:4,2 and hw:4,3 I get 8 ins and 16 outs, which is 3/4 of what
was to
be expected (16 ins and 16 outs).
I know for the delta (1712 based cards) the maximum i/os always shows up
12/10.
I am not so sure with this unit. even with the delta1010/66/44 if you are
using the gui controller (I know you have not seen that) It shows only the
number of adcs and dacs there are (I have a D66). In the monitor mixer
section it shows all the outputs, but only real inputs. You may have some
of the same.
There may be some reason the adat shows only outputs until it is
connected... then it may be 8, 4 or 2 channels depending on rate. (only 8
inputs up to 48k) Or it may be 2 inputs if it is being used as a second
spdif (total of 6 i/o). The real question in my mind is what inputs are
really there in the 8 channels you have now? The pcie1010 reconfigures
itself quite dramatically depending on what is plugged in. Plugging the
dock in makes some of the plugs on the pcie card inactive for example. The
dock and the daughter card can not be used together either.
I think you will find the 16 outputs are there just because they are mixer
inputs. The inputs? I would assume either spdif l/r then ch 1/2 NC 3/4/5/6
or ch1/2 NC 3/4/5/6 and spdif l/r.
I think the adat would have to be plugged in before the system start and
already set to the rate you were going to use as I don't think (correct me
if I am wrong) alsa can dynamically change the number of ports a device
has and jack would find that a problem too. Do you have the bits to test
what is what?
