Looking at the documentation, it seems that there can
be up to 4 devices
hooked up to the card. But each one must have a "dip switch" set to a
different number. In the windows driver I do not think it would matter if
the switch was set to 1, 2 ,3 or 4 because that driver knows how to
connect whichever device to the ice1712. The ice1712 has only 8 inputs
however, and so the linux driver only seems to support one device and I
think it has to say it is device one not 2,3 or 4. I think the linux
driver can work with two devices only if one of them is output only and
the other input only. Reading
http://forums.debian.net/viewtopic.php?f=7&t=79456 tells me that your
input lights should be on to get audio input... they do work in Linux with
the alsa driver. I also notice that he says he realizes the external box
must be set to device number one. Have you checked that?
BINGO! About five years ago, this unit was deployed as part of a 24 channel
audio rack. Checking the switches, this unit had the dip switch set to
1111000000. I set it to 1000000000 and the LEDs lit up, all 8 channels are
receiving input. I guess the OEM drivers don't care what value the switches
are, as long as all the units have different values. FYI No analog volume
tab shows up - the audio is coming in on the monitor input tabs on the
envy24 mixer.
Thanks for your help
