Re: [LAU] icecast and live-streaming

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
