Basically the console kit module is failing to load due to a dbus problem.

Also seems that some other application has your Alsa device open (Device
or resource busy message indicates this), perhaps this means that you
simply can't use your h/w in full duplex mode (e.g. opening the sink
prevents the source from actually working?)

Anyway, actually two bugs there.

FWIW 0.9.14 is a bit of a strange release to use. AFAIK 0.9.16 was the
stable version for a while (fixing bugs in 0.9.12 through 0.9.15), but I
could be wrong.

I'd strongly recommend using 0.9.21 (or rather "stable-queue" git
branch) as many bug fixes have been included since 0.9.14. I'd also
recommend newer alsa kernel and libs too.
