Re: Test Patch6 for Conexant HD Audio.

I just looked over the patch and found that it was incomplete.  In
reviewing my commandline history, I discovered that test6 didn't get the
alsa-kernel base patch (it only had the patch_conexant.c code), required
for building this code.

Here is the real test6 patch.  It should work against both the alsa HG
tip and the alsa-driver-1.0.13.tar.bz2 download.  Earlier versions of
alsa have not been compile tested.
