Hi,
it might be a mixer problem anyway. Some audio cards have that 'capture' channel, which might be hidden by default in the mixer. Can you configure your desktop's mixer and make it show that slider? As you checked the right way, for some cards, jackd gets its input from alsa capture, not from line in directly. So you need to setup your mixer such that capture receives from line in.
Hope this helps?

Hello List,
I'm trying to use rakarrack, and in the process I found that it
gets no input from line-in. (I use qjackctl to make the
appropriate connections.) It's probably not a mixer problem,
because I do hear what's coming in, it just doesn't seem to enter
jackd's world. This is further confirmed by connecting jackmeter
(http://www.ecs.soton.ac.uk/~njh/jackmeter) to alsa_pcm/capture_1
and seeing no signals.
The soundcard is an old SB-something (lspci says: Multimedia
audio controller: Ensoniq 5880 AudioPCI (rev 02)), and I didn't
have this problem with it in an older, Fedora 5 machine. The one
I'm using now is Fedora 7, qjackctl 0.2.20.
Any idea on what to check or try would be appreciated!
Andras
