I am very new to Jack and Linux audio in general, so I
apologize if my questions are silly. I own a POD HD300, and I would like
to use it as a sound card to loopback my guitar sound in the computer
speakers...recording would also be nice. The POD gets appropriately
recognized by the system and its device driver functions properly. In
fact, I can hear sound using Pulse, of course with huge latency. I would
like to use Jack for this (already properly installed and set it up for
real time scheduling).
I have configured Jack from QJackCtl such that
the interface I am using is my POD (interface box in the Setup window -
interface which is different than the one used in Pulse). Now, I cannot
really go on. I guess I have two options to loop my sound back to the
speakers (and please correct me if I am wrong): (1) specifying the input
and output device in the Setup window appropriately; (2) specifying a
proper connection in the Connections window.
Option 1. The Input Device
and Output Device scroll down list in the setup window are only usable
if I select Duplex in the Audio scroll down list. And, in any case, they
only list the audio cards of my PC, not the speakers. I guess, this is
not the right way then. However I have some questions: what are the
Input and Output device scroll down lists good for? And why can they
only be used with duplex?
Option 2. The POD appears only in the ALSA
tab of the Connection window. Therefore I cannot connect it to loopback,
which instead appears in the Audio tab. How can I proceed? And, in
general, what is the difference between the three tabs Audio, Midi, and
ALSA? Why don't I get the POD in the Audio tab as a USB sound
Thanks a lot for helping
