HD-audio spec defines a bit in pin default configuration for indicating
that the pin isn't used for jack-detection although the codec is capable
of it.  Better to check this bit as well in jack_is_detectable() helper
function.

It seems that Conexant CX20549 chip handle only a single input-amp even
though the audio-input widget has multiple sources.  This has been never
clear, and I implemented in the current way based on the debug information
I got at the early time -- the device reacts individual input-amp values
for different sources.  This is true for another Conexant codec, but it's
not applied to CX20549 actually.

This patch changes the auto-parser code to handle a single input-amp
per audio-in widget for CX20549.  After applying this, you'll see only a
single "Capture" volume control instead of separate "Mic" or "Line"
captures when the device is set up to use a single ADC.

We haven't tested 20551 and 20561 codecs yet.  If these show the similar
behavior like 20549, they need to set spec->single_adc_amp=1, too.

In the old Conexant chips (5045, 5047, 5051 and 5066), a single EAPD
may handle both headphone and speaker outputs while it's assigned only
to one of them.  Turning off dynamically leads to the unexpected silent
output in such a configuration with the auto-mute function.

Since it's difficult to know how the EAPD is handled in the actual h/w
implementation, better to keep EAPD on while running for such codecs.

ALC260 has multiple mixer widgets connected to the shared DAC, but the
driver currently doesn't check this possibility and ignores when the DAC
is shared with others.  This resulted in the silent output from some
routes because of lack of the amp setup.

This patch adds the workaround for it by checking the route even with the
shared DAC, but also checking the conflict with the existing control for
the very same widget NID.

When a device has multiple speakers and still has the auto-mute support,
the driver copies line_outs[] to speaker_outs[].  And then it tries to
assign DACs for both.  This ended up with the assignment only to the

The commit ef18bede introduced a
mechanism to assign the previously used slot for the next reopen of a
PCM stream.  But the PCM device number isn't always unique (it may
have multiple substreams), and also the code doesn't check the stream
direction, thus both playback and capture streams share the same
device number.

For avoiding this conflict, make a unique key for each substream and
store/check this value at reopening.

When the speaker outputs are more than the headphone outputs, it implies
that the system has surround speakers while the headphones are only for
monitoring the front.  In such a case, it's better to put speakers as
the primary outputs so that the driver can build up and keep the
surround setup.  Otherwise the system will pick up the headphone as
primary, and offers less channels than the speakers do support.

Added a new option "snoop" for the traffic control of the HD-audio
controller chip.  When set to 0, the non-snooping mode is used with
the traffic control bit is set in each stream control register.
This may allow better operations in the low power mode, but the actual
implementation is depending pretty much on the chipset.

As already implemented, more or less each chipset has own snoop-control
register bit.  Now this setup refers to the snoop option, too.

Also, a new VIA chipset may require the non-snooping mode when set so
in BIOS.  In such a case, the option value is overridden.

As default, it's still set to snoop=1 for keeping the same behavior as
before.  In near future, it'll be set to 0 as default after checking
it works in every system well.

The spec->autocfg.line_out_pins[] may contain the same pins as hp_pins[]
depending on the configuration.  When they are identical, detecting the
line_jack_present flag screws up the auto-mute because alc_line_automute()
is called unconditionally at initialization while it won't be triggered
by unsol events, thus the old line_jack_present flag is kept for the
whole run.

For fixing this buggy behavior, the driver needs to check whether the
line-outs are really individual, and skip if same as headphone jacks.
