You forgot line 163:

bool AudioIO::HardwareParametersSupported(uint channels, int samplerate, uint 
numfragments, uint fragmentsize) {
    pcm_name = "hw:0,0";
...

Change that too and it will automatically fall back to plughw.

Sure, but unfortunately I'm very busy at the moment and I think that will last 
til next week friday; have to take care of lot of projects at university. 
Maybe kick Benno's ass that he should do something, but again; I'm sure you 
can do such small and easy things too and help us to take some of our work 
load.

Benno: what is the event system doing? Anything done in that area?

Btw: is nobody here on the list who wants to participate actively in the 
project? There are a lot of open tasks in all kind of areas and with the end 
of this year we need to start with a GUI.

Anyway, I'm still hopeful that we can finish complete gig support this year...
