Aaron,
I am not running pulseaudio or jackd. As Rafael mentioned I changed
"channel = 2" and now DarkIce no longer errors out when starting so that put
me on a better path than where I have been for the last few days. However
there is no audio being captured. I tried changing the device to hw:0,0
hw:0,2 and default without any success. I added the line to create a local
dump file to hear if anything was being captured. It sounds like a 60Hz hum
with no other audio on all three files - hw00, hw02 and default.

This seems like an ALSA issue.
Out of interest have you tried using it in stereo? Also is anything else
using ALSA e.g. pulseaudio or Jackd?

Has anyone had luck running DarkIce and ALSA using an Intel HDA onboard
audio? I recently purchased an Intel Desktop Board D2500CCE running
Slackware64-14.1 and want to move IceCast/DarkIce off an old system running
Slackware64-14.0. On the old system IceCast/DarkIce and the onboard ASUS/VIA
audio work flawlessly. I figured this would be a simple move however it is
not. I keep getting the error: "DarkIce: AlsaDspSource.cpp:173: can't set
channels [1]" on the new Intel system. After spending a few days searching
the Internet I am not having much success finding a resolution. I am
leaning towards the soundcard as I have reformatted the drive and tried
Slackware-14.0, Slackware-14.1 and Slackware64-14.1. I am able to pipe
audio in through the line-in and get output through the speakers. I also am
able to play a WAV file so I know the onboard sound is working. I checked
the onboard audio settings in the BIOS and only options are to Enable to
Disable the on-board sound.
I have recompiled DarkIce-1.0, DarkIce-1.2, faac, lame, libogg, libvorbis
and two-lame packages under each OS with both DarkIce-1.0 and DarkIce-1.2
presenting the same error: "DarkIce: AlsaDspSource.cpp:173: can't set
channels [1]". The darkice.cfg file is the same copy that works fine on the
old Slackware64-14.0 ASUS system.

I have also tried changing the darkice.cfg device to hw:0,2. Neither

anyone have any pointers for something simple I may be missing?
Thank you in advance for any assistance anyone can provide.
