It's just a workaround :)
The "Digital" capture thing is an implementation in alsa-lib, and it's
a digital gain.

Looking at the problem more deeply, I found a couple of underlying
problems, and now fixed in sound-unstable git tree.

The master branch is 77ecb70ef5b022a1ee80169583753d85d7a9c396,
and test/hda-migrate is 6f7c83afc6cc3f66d13e4ad0a0f5693d9175e1ab.

It might take a bit time until the tree is published on kernel.org
server.  If you still don't see the commit above, just wait for a
while and pull again.

(BTW, now I really migrate both test/hda-gen-parser and
 test/hda-migrate branches, so from now on, both branches point to the
 same code.)


thanks,

Takashi
