What I did was to install Ubuntu with a gui so that I could access the
graphical tools to set everything up and make the config files. After I
got the system working, I dumped X and set up everything command line.
I also had a little issue using jack with darkice and ended up just
connecting darkice straight to ALSA. To do this, I had to build a
custom asound.conf file for my delta1010 audio interface.
/etc/asound.conf
# DELTA1010 .asoundrc START
#pcm.NAME {
# type hw # Kernel PCM
# card INT/STR # Card name or number
# [device] INT # Device number (default 0)
# [subdevice] INT # Subdevice number, -1 first available (default -1)
# mmap_emulation BOOL # enable mmap emulation for ro/wo devices
# }
# Main pcm define
pcm.ice1712 {
type hw
card 0
device 0
}
# adc&dac 1&2
pcm.channel1 {
type plug
ttable.0.0 1
ttable.1.1 1
slave.pcm ice1712
}
# adc&dac 3&4
pcm.channel2 {
type plug
ttable.0.2 1
ttable.1.3 1
slave.pcm ice1712
}
#adc&dac 5&6
pcm.channel3 {
type plug
ttable.0.4 1
ttable.1.5 1
slave.pcm ice1712
}
# adc&dac 7&8
pcm.channel4 {
type plug
ttable.0.6 1
ttable.1.7 1
slave.pcm ice1712
}
/etc/darkice.conf
