    qjackctl wrong in/out firewire ports

    hello
    i don't know what happenend, but when i open 'connect' in qjackctl my firewire interface is represented wrongly, in-channels are on the output ports side and vice versa.
    I just made my system running and got some sound thru guitarix. Then i tested soundlooper without any luck, and now today the system is upside down, grmbl... does someone know about this problem?

    Left are capture, right are playback, or not?
    And these are not firewire ports, just audio ports.

    Hi jejeman,
    ok, i mean audio ports.
    i added a printscreen, it says left side playback, right side capture.
    i remember, while setting up, i had 2 firewire cables connected, did this all mix up? is there a qjackctl config file to check?

    Well, I would take "in" as "capture", and "out" as "playback".
    It can be confusing. It says above:
    On the left: readable clients/output ports, which are practicly hardware input ports
    On the right: writeable clients/input ports, which are practicly hardware output ports.

    It is all alright, belive me.

    When you look this image with simple setup

    You can see how hardware output ports recives signal - that is why it is software input port. And hardware input ports sends signal - that is why it is software output port.

    I hope that this makes it clear.

    Well, the thing is, it's not working anymore. Before i just could start guitarix and jackd and the connections were already there. Now they’re gone.
    Also strange is, that there is an firewire_in and below gx_head_amp out-port. If i connect by hand, i get strange beeps every second. I still doubt that in/out is cranky.

    like i said, i had a proper system, until i fiddled around with audacious and sooperlooper. What happened?!

    Ok, reinstalled qjackctl and jackd with synaptic and somehow it works again. You were right about in/out audio ports, the problem was somewhere else.
