ALSA: hda/realtek - Fix silent headphone output on MacPro 4,1 (v2)

2015-12-22T09:07:45+00:00

Without this patch, internal speaker and line-out work,
but front headphone output jack stays silent on the
Mac Pro 4,1.

This code path also gets executed on the MacPro 5,1 due
to identical codec SSID, but i don't know if it has any
positive or adverse effects there or not.

(v2) Implement feedback from Takashi Iwai: Reuse
     alc889_fixup_mbp_vref and just add a new nid
     0x19 for the MacPro 4,1.

ALSA: hda - Set SKL+ hda controller power at freeze() and thaw()

2015-12-18T08:49:13+00:00

It takes three minutes to enter into hibernation on some OEM SKL
machines and we see many codec spurious response after thaw() opertion.
This is because HDA is still in D0 state after freeze() call and
pci_pm_freeze/pci_pm_freeze_noirq() don't set D3 hot in pci_bus driver.
It seems bios still access HDA when system enter into freeze state,
HDA will receive codec response interrupt immediately after thaw() call.
Because of this unexpected interrupt, HDA enter into a abnormal
state and slow down the system enter into hibernation.

In this patch, we put HDA into D3 hot state in azx_freeze_noirq() and
put HDA into D0 state in azx_thaw_noirq().

V2: Only apply this fix to SKL+
    Fix compile error when CONFIG_PM_SLEEP isn't defined

[Yet another fix for CONFIG_PM_SLEEP ifdef and the additional comment
 by tiwai]

ALSA: hda - Add a fixup for Thinkpad X1 Carbon 2nd

2015-12-15T14:11:59+00:00

Apply the same fixup for Thinkpad with dock to Thinkpad X1 Carbon 2nd,
too.  This reduces the annoying loud cracking noise problem, as well
as the support of missing docking port.

ALSA: hda - Set codec to D3 at reboot/shutdown on Thinkpads

2015-12-15T14:11:58+00:00

Lenovo Thinkpads with Realtek codecs may still have some loud
crackling noises at reboot/shutdown even though a few previous fixes
have been applied.  It's because the previous fix (disabling the
default shutup callback) takes effect only at transition of the codec
power state.  Meanwhile, at reboot or shutdown, we don't take down the
codec power as default, thus it triggers the same problem unless the
codec is powered down casually by runtime PM.

This patch tries to address the issue.  It gives two things:
- implement the separate reboot_notify hook to struct alc_spec, and
  call it optionally if defined.
- turn off the codec to D3 for Thinkpad models via this new callback

ALSA: hda - Apply click noise workaround for Thinkpads generically

2015-12-15T14:06:14+00:00

It seems that a workaround for Thinkpad T440s crackling noise can be
applied generically to all Thinkpad models: namely, disabling the
default alc269 shutup callback.  This patch moves it to the existing
alc_fixup_tpt440_dock() while also replacing the rest code with
another existing alc_fixup_disable_aamix().  It resulted in a good
code reduction.

ALSA: hda - Fix noise problems on Thinkpad T440s

2015-12-09T14:31:21+00:00

Lenovo Thinkpad T440s suffers from constant background noises, and it
seems to be a generic hardware issue on this model:
  https://forums.lenovo.com/t5/ThinkPad-T400-T500-and-newer-T/T440s-speaker-noise/td-p/1339883

As the noise comes from the analog loopback path, disabling the path
is the easy workaround.

Also, the machine gives significant cracking noises at PM suspend.  A
workaround found by trial-and-error is to disable the shutup callback
currently used for ALC269-variant.

This patch addresses these noise issues by introducing a new fixup
chain.  Although the same workaround might be applicable to other
Thinkpad models, it's applied only to T440s (17aa:220c) in this patch,
so far, just to be safe (you chicken!).  As a compromise, a new model
option string "tp440" is provided now, though, so that owners of other
Thinkpad models can test it more easily.

ALSA: hda - Fixing speaker noise on the two latest thinkpad models

2015-12-08T06:28:14+00:00

We have two latest thinkpad laptop models which are all based on the
Intel skylake platforms, and all of them have the codec alc293 on
them. When the machines boot to the desktop, an greeting dialogue
shows up with the notification sound. But on these two models, there
is noise with the notification sound. We have 3 SKUs for each of
the models, all of them have this problem.

So far, this problem is only specific to these two thinkpad models,
we did not find this problem on the old thinkpad models with the
codec alc293 or alc292.

A workaround for this problem is disabling the aamix.
