"Wave Surround", "Wave Center" and "Wave LFE" don't have to be muted

This defines two modem related pcm devices: "phoneline" is driver's pcm
reference, with "modem" the line will be "Hook-Off"ed automatically.

- Fix surround40 channel numbers
- Fix rear/center_lfe channel assignment
This configuration is based on the channel order on Revo 7.1,
Front/CLFE/Surr/Side
If the other ice1724-based boards have a different order, we need
to rename the driver's id to distinguish the difference.
From: Julian Scheel <julian@jusst.de>
Hi all,
attached is an updated ICE1724.conf - I have added channels X parameters to
the .pcm.surroundXX-fields, because otherwise it's for example not possible
to play a 5.1-stream on surround51 and a stereo-stream on side simultaneous.
I need this feature to do multiroom-sound through one single sound-card (one
room playing a DVD with 5.1, another room playing some MP3s through channels
7 and 8).
I hope you could follow my explanations and will add this to the tree.
Cheers,
Julian
- separated the "base library" from ac97.c (dynamically loaded)
- added necessary handling of all private structures
- added selector and sid registration functions and handling code
- added basic code for hda.c (yeah, my notebook has this hw)
- exported all necessary functions to create a mixer module outside alsa-lib
- separated simple mixer API from the simple mixer implementation
(using callbacks as usuall)
- src/mixer/simple.c is the core
- src/mixer/simple_none.c is the current (no-abstraction) implementation
based on control names; note that this module does not depend on
internal ALSA structures now
- src/mixer/simple_abst.c is the ongoing abstraction which will use
external dynamic modules; src/conf/smixer.conf will describe which
modules will be used depending on the components from the driver
Call hwsync of slave PCM on snd_pcm_hwsync() over dmix.
This reduces ocasional output noises, typically seen in xmms and bmp with
multi-threading on SMP/HT systems.
Disabled slowptr of default dmix definition again.
This patch adds a DSP patch to fix an spdif_bug on some Audigy2 cards.
It also does detailed identification of the capabilities of the sound
card so that the patch is only applied to the sound cards that really
need it.

"default" PCM can be card-specific.
The definition is moved to pcm/default.conf, and read on-demmand via
aliases.conf. The card config can override the default config.
