7fe307117d ALSA: hda - Fix inconsistent Mic mute LED
The current code for controlling mic mute LED in patch_sigmatel.c
blindly assumes that there is a single capture switch.  But, there can
be multiple multiple ones, and each of them flips the state, ended up
in an inconsistent state.

For fixing this problem, this patch adds kcontrol to be passed to the
hook function so that the callee can check which switch is being
accessed.  In stac_capture_led_hook(), the state is checked as a
bitmask, and turns on the LED when all capture switches are off.

f8f1becfa4 ALSA: hda - Fix leftover ifdef checks after modularization
Since the commit [595fe1b702c3: ALSA: hda - Make
CONFIG_SND_HDA_CODEC_* tristate], the kconfig variables for the
generic parser and codec drivers can be "m" instead of boolean, but
some codes are left unchanged to check only #ifdef
CONFIG_SND_HDA_CODEC_XXX, which is no longer true for modules.
This patch fixes them by replacing with IS_ENABLED() macros.

276ab336b4 ALSA: hda - Improve loopback path lookups for AD1983
AD1983 has flexible loopback routes and the generic parser would take
wrong path confusingly instead of taking individual paths via NID 0x0c
and 0x0d.  For avoiding it, limit the connections at these widgets so
that the parser can think more straightforwardly.  This fixes the
regression of the missing line-in loopback on Dell machine.

d3c56568f4 ALSA: hda/realtek - Avoid invalid COEFs for ALC271X
We've seen often problems after suspend/resume on Acer Aspire One
AO725 with ALC271X codec as reported in kernel bugzilla, and it turned
out that some COEFs doesn't work and triggers the codec communication
stall.

Since these magic COEF setups are specific to ALC269VB for some PLL
configurations, the machine works even without these manual
adjustment.  So, let's simply avoid applying them for ALC271X.

75fae117a5 ALSA: hda/hdmi - allow PIN_OUT to be dynamically enabled
Commit 384a48d71520 "ALSA: hda: HDMI: Support codecs with fewer cvts
than pins" dynamically enabled each pin widget's PIN_OUT only when the
pin was actively in use. This was required on certain NVIDIA CODECs for
correct operation. Specifically, if multiple pin widgets each had their
mux input select the same audio converter widget and each pin widget had
PIN_OUT enabled, then only one of the pin widgets would actually receive
the audio, and often not the one the user wanted!

However, this apparently broke some Intel systems, and commit
6169b673618b "ALSA: hda - Always turn on pins for HDMI/DP" reverted the
dynamic setting of PIN_OUT. This in turn broke the afore-mentioned NVIDIA
CODECs.

This change supports either dynamic or static handling of PIN_OUT,
selected by a flag set up during CODEC initialization. This flag is
enabled for all recent NVIDIA GPUs.

3d692451ea ALSA: hda - Do not accept responses from non-existing codecs
While looking into some spurious responses, I found that the addr value was
treated a bit inconsistent: values 8..0xf will be treated as codec 0 and
values 0..7 will be treated as no error regardless of whether there is a codec
there, or not.

With this patch, all non-existing codecs will be treated equally.
In addition, printing rp and wp could help figuring out if the wp value is
reported wrongly from the controller or if something else is wrong.

3a00c6605b ALSA: hda/conexant - Re-implement OLPC XO workarounds via fixup
OLPC XO needs a few special handling.  Now these are implemented as a
fixup to the generic parser.

Obviously, the DC BIAS mode had to be added manually.  This is mainly
implemented in the mic_autoswitch hook, where the mic pins are
overwritten depending on the DC bias mode.  This also required the
override of the mic boost control, since the mic boost is applied only
when the DC mode is disabled.

In addition, the mic pins must be set dynamically at recording time
because these also control the LED.

Processing coefficients are often a vital part of the codec's configuration,
so dumping them can be important. However, because they are undocumented and

Therefore instead add this as a debugging parameter.

I have prepared for codecs that want to enable this by default by the extra

(unlikely, but still) race remains.

cf67c8e71b ALSA: hda - Fix endless vmaster hook call in thinkpad_helper.c
The new vmaster hook, update_tpacpi_mute_led(), calls the original
vmaster hook, but I forgot to save the original hook function but keep
calling the updated one, which of course results in a stupid endless
loop.  Fixed now.

493a52a9b6 ALSA: hda - automute via amp instead of pinctl on some AIO models
On some AIO (All In One) models with the codec alc668
(Vendor ID: 0x10ec0668) on it, when we plug a headphone into the jack,
the system will switch the output to headphone and set the speaker to
automute as well as change the speaker Pin-ctls from 0x40 to 0x00,
this will bring loud noise to the headphone.

I tried to disable the corresponding EAPD, but it did not help to
eliminate the noise.

According to Takashi's suggestion, we use amp operation to replace the
pinctl modification for the automute, this really eliminate the noise.
