Check what is reported in the ices log file, see if the requested
settings are being accepted. Some devices only accept certain rates like
48000 for instance.

Can you describe the interference, are the levels too high for instance,
are unused inputs muted ?

Can you do some straight recording with rec/sox without interference.

The alsa drivers aren't too bad, there are some extra lines from the
modules.conf for automatic loading.  The alsa site does describe them
though, http://www.alsa-project.org/alsa-doc/
