Darkice config file
This is the config file for darkice under Linux, to stream on radio.dyne.org, use darkice as darkice -c darkice.cfg where darkice.cfg is the configuration file:
With OSS (OLD :-? Open Sound System)
Control permissions and existance of /dev/dsp dsp1 dsp2, dependently from how many audio cards you have. Tri gom or aumix to control the mixer settings.

With ALSA
Control that there is an audio card with aplay -l and always control that you are part of group audio ( or be root )

{i}{X}X-({X}{i} |

On ubuntu ( and on debian to be tried ) pulseaudio take over hw:0,0 so your audiocard will be hw:1,0 (blarg...). There must be a more gently way of killing pulseaudio and clearing this naming issue... to be investigated :) |

fileAddDate = yesControl the mixer with alsamixer ( alsamixer -c1 in case of pulseaudio cadaver )
In alsamixer press the [tab] button on your keyboard to go to the input capture view:
Don't put the capture volume at max or you will get poor quality audio, if your terminal supports colors keep it under the red bar :), in amixergui or thing like that keep the capture volume 2/3 of the max volume.
With the arrows you can cross the input channels, put the capture on the -mix- by pressing the space bar and then set the volumes of the outputs ( again [tab] to switch back to the outputs volumes views) as you wish.
If you plan to use a player like mplayer or audacious or xmms remember to set them to use Master as volume and not PCM otherwise with the music you will take down also mikes line-in cd and what-sallamadonna-not , best to set them on software volume control ( -softvol for mplayer )
