This is from the Wiki at http://audacityteam.org/wiki/index.pl?LinuxIssues
Audacity can use ALSA natively if you compile it to use
PortAudio v19 instead of the default, v18. Note that v19 is
still evolving and not as well tested, but it is the only
way that Audacity supports ALSA. Many users have reported
good experiences with it. To use it, reconfigure Audacity
like this:
./configure --with-portaudio=v19 --without-portmixer

Not it pure OSS probably, but you could use libaoss to let
Audacity-OSS talk to ALSA devices without knowing it does so.
But actually I record radio a lot with ecasound, which has the
advantage, that it can be put into a cronjob and thus can even record,
when I'm away/asleep.
