I also use gentoo, you should be sure that your user is a member of the
audio group, so that you have permission to write to the audio device,
else it should be fine, I use /dev/dsp which is just a symlink to the
device you specified.
Have you enabled capture on the line port? (use e.g. alsamixer and press
spacebar on the port).
