Any reasonable distro will hide these implementation details from the

No I believe it actually sets the ALSA "default" device by modifying the
ALSA config files or module config. I can't test it as I only have the
one card. This is a Gnome 2.14 feature.

These are distro bugs, apparently Debian does not ship the driver for
your card (probably due to firmware loadibng issues), and of course
Gentoo requires you to do it manually.

File bug reports with your distro(s).
