    I can't see setting for device and I/O in Jamulus Linux. Did I compile badly?
    thank you

    In the Linux version of Jamulus, you cannot select the audio interface directly within the Jamulus software. You have to select the audio interface in the Jack control tool (e.g. QJackCtl).

    Fine Volker, I confirm I set Interface in QJackCtl to my Pandora PX5D (hw:1,0).
    Jamulus could launch before, but now when I run Jamulus, I get error "The Jack server sample rate is different from the required one. The required sample rate is: 48000 Hz. You can use a tool like QJackCtl to adjust the Jack server sample rate..." when QJackCtl ran jackd with 128/48kHz/3 (Although QjackCtl main GUI shows 44100Hz). Maybe some issue between QjackCtl and Jack itself?

    Well I found why I always have issues: jack can run 48k samplerate, but as soon as I select qjackctl interface hw:1,0 it switches to 44k1. When I select hw:1, it remains at 48k but the sound goes to/from hw:0 :(
    No way I can use Jamulus with my Pandora PX5D
    ubuntu 13.04
    kernel 3.8.0 64bits
    qjackctl 0.3.9
    alsa 1.0.25

    OK, just to close the thread, I could workaround by running alsa_in -dhw:PX5D and according settings in [q]jack[ctl].
    Maybe this is not the perfect way, so I ordered an UCA202.
