Doh, sorry for the trouble.
Could you give alsa-info.sh output?  Most distros already installed
the script, or it can be taken from
   http://www.alsa-project.org/alsa-info.sh

Run the script with --no-upload option and attach the output.
It allows me to run the emulator with your configuration, so I can
debug more certainly.


thanks,
