[Icecast] Newbie problem with ices2

[Richard]

Hi all,

I'm fairly new to icecast / ices - been using icecast (2.2.0) to stream 
audio files for a few weeks, it works very well, now I'm trying to add 
live feeds via ices (v2.0.1). I've built and installed (on SuSE 9.3 
platform) with no apparent errors, copied ices-alsa.xml to user area and 
modified paths, server password etc.

When I run ices (using "ices  /home/rpm/Music/ices-alsa.xml" it starts 
OK then after a few seconds I get
"EROR input-alsa/alsa_read snd_pcm_readi failed: Input/output error" and 
it dies (icecast stays up though).

All I'm trying to do is to stream from line-in, I used kmix to set this 
(I think... red lights on for 'line' and 'capture' in the input tab).

Has anyone any idea please what's going wrong?
Thanks,
