With all the "best of 2005" shows coming up on FM radio, I had this
idea that I might be able to record the programs to disk (mp3?).
I normally control my FM radio card using the GKrellm plugin and
the various input/output channels with 'kmix'.
Thanks for your ideas!

Is there a question hidden in this mail?
If there is and if it is: "How do I record from a FM radio card?" then
that's easy: use "radio" to tune in the channel you want to record,
then use "ecasound" to record directly to ogg/mp3, all this can be
controlled by a cronjob.

I finally had time to try your suggestion ...
Among other commands, I used the following after first "turning on"
the radio:
% ecasound -i:alsa -o radio.wav
This produced a file containing constant values (== silence when
played with 'xmms'). My hunch is I've not specified the correct ALSA
"device".
I checked some of the ALSA docs, the output of 'dmesg', and looked
around within 'alsamixergui', but don't really know what to do.
Note that the output of the radio/tv card is connected with a wire to
the (line?) input of the SBL! audio card.
Thanks for the help!

Check output of "arecord -l" to get a list of all cards currently
available via ALSA.
Then choose the card number to use, and then use:
arecord -D plughw:N foo.wav
ecasound -i alsa,plughw:N -o foo.wav
...
... where 'N' is the soundcard number. If you run ecasound with "-i
alsa",
that's equivalent to "-i alsa,default". The "default" device is
usually
the first soundcard in your system (-> "plughw:0").
PS You can also use "arecord -L" to get even more information
about the available ALSA devices.

Thanks for your suggestions.
As it turned out, I went to my office Debian system and "things just
worked"! Since I was able to record off of FM radio there for about
5-6 hours (>600MB of mp3!) straight without "issues", I pretty much
gave up trying to get it to work on my home machine. Even wrote a
little script that runs in 'cron' to capture NPR headlines at the
top-of-the-hour ...
Then the new semester started. :-(
Anyway, I appreciate everyone's help. When I get a bit caught up,
I'll return to getting 'ecasound' and ALSA to cooperate at home.
Thanks again,
-Kenneth
