Hello everyone!
I had a USB audio device here, a Zoom h4n, portable recorder/audio
interface. When I connect it to my box, it shows up and ALSA finds it.
First: ALSA can't open the mixer, no elemtns found, alsamixer says.
Second: I can't use JACK with it, although I read on some forum, that a
chap managed with Fedora FC6. JACK tells me something about broken pipe. It
runs, but there's no sound and I definitely have to "killall -9" it. :-( I
tried JACK with different period sizes (-p) and different frames per period
(-n), different samplerates, although I can set these on the Zoom, before I
connect it. As I said: ALSA can record from it and play sounds using it.
Does anyone of you have an idea on the subject?
Hey Julien,
I have a zoom H4 that I use with jack all the time. It is set to 44.1 from the
hardware side.
Qjackctl starts it thusly:
/usr/bin/jackd -dalsa -r44100 -p1024 -n3 -D -Chw:1 -Phw:1
(taken from ps ax | grep jack)
I can run it with lower latency when I need to but I don't push it for my
simple daily recording. I have used ardour with it but these days mostly use
traverso as my needs are very simple for my daily stuff.
uname -a gives
Linux zriven 2.6.24-24-rt #1 SMP PREEMPT RT Wed Apr 15 18:09:25 UTC 2009 i686

Kindest regards
Julien
all the best,
