[PATCH v5 00/10] Audio: Mixeng-free 5.1/7.1 audio support

["Kővágó, Zoltán" <dirty.ice.hu@gmail.com>]

Hi,

I've updated my mixeng-free audio patches.  The documentation probably
requires more polishing, but I'm sending this now so the other parts
can be reviewed too.

Changes from v4:

* Removed already merged commits.
* Bugfix in "audio: make mixeng optional" commit.
* Dropped the "paaudio: channel-map option" patch, instead the paaudio
  backend will automatically figure out the current channel map for now
  (see the last patch).  Currently this only works with usb-audio, if
  other frontends gain support for multi-channel audio, it might require
  some rethinking.

Regards,
Zoltan
