Since there's not a cdda2wav component, I'm filing this under cdrecord.
I think the command
$ cdda2wav -D <device>
should dump just the first track of a music CD, and so it does.
It outputs something different, though:
100% track 1 successfully recorded
100% track 2 successfully recorded
It does the right thing (dumps 1 track, and I can see just 1 inf and 1 wav
file), but says it dumped 2 tracks.
Confirmed - now it doesn't show the line of the second dump anymore, but it
still says it has dumped two tracks. Weird.
Fixed in 1.9, released yesterday.
