Thanks Clemens.  I have never patched alsa before.  Is there a guide
or documentation that might help me with this?  I'm working with an
out of the box Linux distro.  I'm not exactly sure about what packages
I would need to remove from my system, what source packages I would
need to compile (I see driver, firmware, library, etc. on the download
page), and how to install/test them after recompiling.

I appreciate your help.

John
