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!

Hi!
Did you have a look at howmany capture_* ports there are? Perhaps there are
special ports for microphone?
Did you check with simple alsa-tools? arecord or something like it, to see
if ALSA handles it?
Are you 100% sure your connecting cables are all right? Don't laugh, I had
that ones and wouldn't believe it. :-(
Did you try the mixer anyway? alsamixer or alsamixergui?
That's all I'd have.
Kindest regards
Julien

Hi Julien, thanks for the quick response!

That was it! arecord didn't record anything, so the problem was on the
ALSA side.
But now that that part is fixed there's a new problem: I get a lot of
hiss when I connect the capture ports to rakarrack's input ports. I
muted almost everything in alsamixer, but that didn't help. It's as if
rakarrack's output were connected to its input - but it's not. Maybe
now I'm indeed facing a jackd (or a rakarrack) problem...

These things happen, I know... but probably not this time.

alsamixergui?
I learned now that alsamixer had more controls (activated by TAB) than
what can be seen by default.
That's all I'd have.
Thanks a lot!

Cards like that usually have an option in the mixer to choose which
input you want to record from (line in, microphone, etc.); make sure
it's set correctly.

Ah! After reading Julien's message, I played a bit more with
alsamixer, and finally I thought I set it correctly, because I was
able to arecord. But appearently not! I got the hisses (with
rakarrack) because it was set to capture, but not from line-in! (Why
arecord worked is a mystery to me.) But now that you mentioned it, I
see that one can indeed choose the source; and now it all seems to
work!
Thanks a lot!
