A control 'device' is a set of all controls for an entire card.

That is, xmcd always uses mixer element "PCM",0 and assumes that this
is the stream it's playing to? Complain to the author of xmcd ... :-(

I guess gnome uses an OSS device like /dev/dsp.
ALSA's hw:0,0 is OSS device /dev/dsp0.
ALSA's hw:0,1 is OSS device /dev/adsp0.
/dev/dsp usually is a symlink to /dev/dsp0.
Either tell gnome to use /dev/adsp0 (there must be a configuration
setting somewhere), or try to change /dev/dsp:
rm /dev/dsp
ln -s /dev/adsp0 /dev/dsp
