Hi!

Here's how to write your own:

http://www.freedesktop.org/wiki/Software/PulseAudio/Backends/ALSA/Profiles

If you come up with a good profile (or set of profiles) that would also 
benefit other Delta1010 users, would you mind posting it here 
(preferably as a patch if you know how), so that we can include it in 
future versions of PulseAudio?

Thanks!
