    Dear All,

    When running llcon after I started qjackctl I got the error "Cannot find any physical capture ports" Any suggestion how to handle this?

    I have a USB guitar link with mono input, currently I can not use it with Jamulus, because Jamulus insists on stereo input. Why is stereo input a hard requirement, can't stereo input be optional?

    Another question: so - it's not possible to route output from guitarix into Jamulus? Jamulus insists on physical ports... is this a limitation because of latency, meaning: I do have to connect a real amplifier to my soundcard's input? Or are there other reasons?

    Just trying to understand... thanks :)

    Thank you for pointing me to the problem that mono input/output devices are not supported. I have fixed this issue. The latest CVS code should work now for you.

    Can you please try out if the fix works for you? Just check out the latest code from the Jamulus CVS.

    Uhh.. CVS, that has been a while hinthintgit ;) Thank you, it works with my mono usb guitar-link now!

    What about further routing? I did hack your code a bit so that I can route through guitarix, that seems to work although we could not really test it because our pings on the public servers were not good enough.

    I changed the code again. I do not fire an error message any more if no physical ports are available in the system. I simply do not make any default connection in that case. That should hopefully do the trick.
