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


Now, is there any tricky mapping of channels, probably with .asoundrc, so that the line-in signal shows up in ch. 1 and 2?


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.

Thanks, Frank, for your suggestions. I didn't dive into ecasound yet, and I don't catch the logics behind aoss, so I tried to compile audacity-1.2 with the portaudio-v19 option:


Hard stuff, I got the same compile errors mentioned on the wiki page, and I didn't succeed until I copied an original portaudio snapshot from their homepage INTO the audacity source.

Now I have two i/o devices in audacity: /dev/dsp again and "TerraTec DMX6Fire", which, until now, seems to be unusable.

I'll keep on trying ...
