wspr crashes after first listening run

Hi all,

Today I installed WSPR on my new shiny Ubuntu 14.10 desktop machine following http://sourceforge.net/p/wsjt/mailman/message/32576671/. After fiddling with user rights to allow CAT operation using /dev/ttyUSB0 by my non-privileged user account, WSPR executes and can control my rig.

Now I configured the soundcard, which was a bit unclear because it was not apparent to me what was which device (I have two soundcards: an ALC662 and a CA0106(Creative Labs). For the ALC662 the entries in the configuration window were labeled Microphone and Speakers, but for the CA0106 it was named hw1,0 etc. After picking hw1,0 and hw1,1 it seems to work, because now it starts receiving and there also seems to be audio coming in.

However, after two minutes WSPR crashes with a message that the audio device is unavailable. Anyone knows what's happening? I don't have deep knowledge about Alsa/PortAudio/Jack etc. What exactly is required for WSPR operation?

To be complete I will paste the output of the program when running it from a terminal window:
