The laptop has a combined jack to attach headsets on the right.
The BIOS encodes them as two different colored jacks at the front,
but otherwise it seems to be configured ok. But any adaption of
the pins config on its own doesn't fix the jack detection to work
in Linux. Still Windows works correct.
This is somehow fixed by chaining ALC256_FIXUP_ASUS_HEADSET_MODE,
which seems to register the microphone jack as a headset part and
also results in fixing jack sensing, visible in dmesg as:
-snd_hda_codec_realtek hdaudioC0D0: Mic=0x19
+snd_hda_codec_realtek hdaudioC0D0: Headset Mic=0x19
[ Actually the essential change is the location of the jack; the
driver created "Front Mic Jack" without the matching volume / mute
control element due to its jack location, which confused PA.

It's reported that the garbled sound on HP Envy x360 13z-ag000 (Ryzen
Laptop) is fixed by the same workaround applied to other AMD chips.
Update the driver_data entry for Raven (1022:15e3) to use the newly
introduced preset, AZX_DCAPS_PRESET_AMD_SB. Since it already contains
AZX_DCAPS_PM_RUNTIME, we can drop that bit, too.

ASoC: Updates for v5.4
Quite a big update this time around, particularly in the core
where we've had a lot of cleanups from Morimoto-san - there's
not much functional change but quite a bit of modernization
going on. We've also seen a lot of driver work, a lot of it
cleanups but also some particular drivers.
- Lots and lots of cleanups from Morimoto-san and Yue Haibing.
- Lots of cleanups and enhancements to the Freescale, sunxi dnd
Intel rivers.
- Initial Sound Open Firmware suppot for i.MX8.
- Removal of w90x900 and nuc900 drivers as the platforms are
being removed.
- New support for Cirrus Logic CS47L15 and CS47L92, Freescale

This notebook has 6 built in speakers for 5.1 surround support, however
only two got autodetected and have also not been assigned correctly.
This patch enables all speakers and also fixes muting when headphones are
plugged in.
The speaker layout is as follows:
pin 0x15 Front Left / Front Right
pin 0x18 Front Center / Subwoofer
pin 0x1b Rear Left / Rear Right (Surround)
The quirk will be enabled automatically on this hardware, but can also be
activated manually via the model=aspire-ethos module parameter.
Caveat: pin 0x1b is shared between headphones jack and surround speakers.
When headphones are plugged in, the surround speakers get muted
automatically by the hardware, however all other speakers remain
unmuted. Currently it's not possible to make use of the generic automute
function in the driver, because such shared pins are not supported.
If we would change the pin settings to identify the pin as headphones,
the surround channel and thus the ability to select 5.1 profiles would
get lost.
This quirk solves the above problem by monitoring jack state of 0x1b and
by connecting/disconnecting all remaining speaker pins when something
gets plugged in or unplugged from the headphones jack port.

This ThinkCentre machine has a new realtek codec alc222, it is not
in the support list, we add it in the realtek.c then this machine
can apply FIXUPs for the realtek codec.
And this machine has two front mics which can't be handled
by PA so far, it uses the pin 0x18 and 0x19 as the front mics, as
a result the existing FIXUP ALC294_FIXUP_LENOVO_MIC_LOCATION doesn't
work on this machine. Fortunately another FIXUP
ALC283_FIXUP_HEADSET_MIC also can change the location for one of the
two mics on this machine.

The recent change to shuffle the codec initialization procedure for
Realtek via commit 607ca3bd220f ("ALSA: hda/realtek - EAPD turn on
later") caused the silent output on some machines. This change was
supposed to be safe, but it isn't actually; some devices have quirk
setups to override the EAPD via COEF or BTL in the additional verb
table, which is applied at the beginning of snd_hda_gen_init(). And
this EAPD setup is again overridden in alc_auto_init_amp().
For recovering from the regression, tell snd_hda_gen_init() not to
apply the verbs there by a new flag, then apply the verbs in
alc_init().

Currently we disallow the runtime PM of the HD-audio controller if
it's bound with HDMI/DP on Nvidia / AMD unless it's for dGPU. This is
for keeping the link up to get the proper notification for ELD
hotplug.
As explained in the commit 37a3a98ef601 ("ALSA: hda - Enable runtime
PM only for discrete GPU"), this keep-power-up behavior is rather a
stop-gap solution until the ELD notification via audio component.
And now we finally got the audio component for these graphics drivers
via commit ade49db337a9 ("ALSA: hda/hdmi - Allow audio component for
AMD/ATI and Nvidia HDMI"), so it's time to change.
This patch makes HD-audio controller again runtime-suspendable when
the device gets bound with audio component in HDMI codec driver. For
making it easier to access from the codec driver, move the flag into
the common hda_bus object instead of hda_intel flag. Also rename it
to keep_power, to indicate the actual meaning.

We plan to define a new tbl which will match more machines with a

Currently we set hdac_stream.fifo_size field only for the playback
stream by some odd reason I forgot, while this field isn't referred in

Pull HD-audio bus ops cleanups.
Signed-off-by: Takashi Iwai <tiwai@suse.de>

HD-audio drivers access to the mmio registers indirectly via the
corresponding bus->io_ops callbacks. This is because some platform
(notably Tegra SoC) requires the word-aligned access. But it's rather
a rare case, and other platforms suffer from the penalties by indirect
calls unnecessarily.
This patch is an attempt to optimize and cleanup for this situation.
Now the special aligned access is used only when a new kconfig
CONFIG_SND_HDA_ALIGNED_MMIO is set. And the HD-audio core itself
provides the aligned MMIO access helpers instead of the driver side.
If Kconfig isn't set (as default), the standard helpers like readl()
or writel() are used directly.
A couple of places in ASoC Intel drivers have the access via io_ops
reg_writel(), and they are replaced with the direct writel() calls.
And now with this patch, the whole bus->io_ops becomes empty, so it's
dropped completely. The bus initialization functions are changed
accordingly as well to drop the whole bus->io_ops.

The HD-audio core allocates and releases pages via driver's specific
dma_alloc_pages and dma_free_pages ops defined in bus->io_ops. This
was because some platforms require the uncached pages and the handling
of page flags had to be done locally in the driver code.
Since the recent change in ALSA core memory allocator, we can simply
pass SNDRV_DMA_TYPE_DEV_UC for the uncached pages, and the only
difference became about this type to be passed to the core allocator.
That is, it's good time for cleaning up the mess.
This patch changes the allocation code in HD-audio core to call the
core allocator directly so that we get rid of dma_alloc_pages and
dma_free_pages io_ops. If a driver needs the uncached pages, it has
to set bus->dma_type right after the bus initialization.
This is merely a code refactoring and shouldn't bring any behavior
changes.

A long-time problem on the recent AMD chip (X370, X470, B450, etc with
PCI ID 1022:1457) with Realtek codecs is the crackled or distorted
sound for capture streams, as well as occasional playback hiccups.
After lengthy debugging sessions, the workarounds we've found are like
the following:
- Set up the proper driver caps for this controller, similar as the
other AMD controller.
- Correct the DMA position reporting with the fixed FIFO size, which
is similar like as workaround used for VIA chip set.
- Even after the position correction, PulseAudio still shows
mysterious stalls of playback streams when a capture is triggered in
timer-scheduled mode. Since we have no clear way to eliminate the
stall, pass the BATCH PCM flag for PA to suppress the tsched mode as
a temporary workaround.
This patch implements the workarounds. For the driver caps, it
defines a new preset, AXZ_DCAPS_PRESET_AMD_SB. It enables the FIFO-
corrected position reporting (corresponding to the new position_fix=6)
and enforces the SNDRV_PCM_INFO_BATCH flag.
Note that the current implementation is merely a workaround.
Hopefully we'll find a better alternative in future, especially about
removing the BATCH flag hack again.

The legacy HD-Audio driver cannot handle Skylake+ platforms with
digital microphones. For those platforms, the SOF or SST drivers need
to be used.
This patch provides an automatic way of detecting the presence of
DMICs using NHTL information reported by the BIOS. A kernel kconfig
option or a kernel module parameter provide an opt-in means of
stopping the probe. The kernel would then look for an alternate driver
registered for the same PCI ID to probe.
With this capability, distros no longer have to blacklist
snd-hda-intel, but still need to make sure the SOF/SST drivers are
functional by providing the relevant firmware and topology files in
/lib/firmware/intel
The coexistence between SOF and SST drivers and their dynamic
detection is not addressed by this patch, different mechanisms need to
be used, e.g. DMI-based quirks.

It turned out that the recent Intel HD-audio controller chips show a
significant stall during the system PM resume intermittently. It
doesn't happen so often and usually it may read back successfully
after one or more seconds, but in some rare worst cases the driver
went into fallback mode.
After trial-and-error, we found out that the communication stall seems
covered by issuing the sync after each verb write, as already done for
AMD and other chipsets. So this patch enables the write-sync flag for
the recent Intel chips, Skylake and onward, as a workaround.
Also, since Broxton and co have the very same driver flags as Skylake,
refer to the Skylake driver flags instead of defining the same
contents again for simplification.

snd_hdac_ext_bus_device_exit() has been recently modified
to no longer free the hdac device. SOF allocates memory for
hdac_device and hda_hda_priv with kzalloc. Make them
device-managed instead so that they will be freed when the

Because of the above change, hda_codec is device-managed and
it will be freed when the ASoC device is removed. Freeing
the codec in snd_hda_codec_dev_release() leads to kernel
panic while unloading and reloading the ASoC driver. So,
avoid freeing the hda_codec for ASoC driver. This is done in

which has the hallmarks of a worker queued from interrupt after it was
supposedly cancelled (note the POISON_FREE), and I could not see where
the interrupt would be flushed on shutdown so added the likely suspects.

AMD/ATI and Nvidia HDMI codec drivers didn't have the audio component
binding like i915, but it worked only with the traditional HD-audio
unsolicited event for the HDMI hotplug detection and the ELD read-up
thereafter. This has been a problem in many ways: first of all, it
goes through the hardware event transition (from GPU register write,
HD-audio controller trigger, and finally to HD-audio unsolicited event
handling), which is often unreliable and may miss some opportunities.
Second, each unsol event handling and ELD read-up need the explicit
power up / down when the codec is in the runtime suspend. Last but
not least, which is the most important, the hotplug wakeup may be
missed when the HD-audio controller is in runtime suspend. Especially
the last point is a big problem due to the recent change relevant with
vga_switcheroo that forcibly enables the runtime PM for AMD HDMI
controllers.
These issues are solved by introducing the audio component; the
hotplug notification is done by a direct function callback, which is
more accurate and reliable, and it can be processed without the actual
hardware access, i.e. no runtime PM trigger is needed, and the
HD-audio gets the event even if it's in runtime suspend. The same for
ELD query, as it's read directly from the cached ELD bytes stored in
the DRM driver, hence the whole hardware access can be skipped.
So here it is: this patch implements the audio component binding with
AMD/ATI and Nouveau DRM drivers. The biggest difference from i915
implementation is that this binding is fully optional and it can be
enabled asynchronously on the fly. That is, the driver will switch
from the HD-audio unsolicited event to the notify callback once when
the DRM component gets bound. Similarly, when DRM driver gets
unloaded, the HDMI event handling returns to the legacy mode, too.
Also, another difference from i915 is that the new code registers the
component in the codec driver, while i915 HDMI codec assumes the
component binding was already done in the HD-audio controller driver.
Hence the new code does need to de-register the component binding at
the codec exit, too.
Some other details:
- The match component ops assumes that both VGA and HD-audio
controller PCI entries belong to the same PCI bus, and only accepts
such an entry.
- The pin2port audio_ops is implemented with assumption of the fixed
widget layout. For AMD, it's starting from 3, with step 2 (3, 5, 7,
...), while for Nvidia, it's starting from 4, with step 1 (4, 5, 6,
...)
As of this patch, the corresponding component isn't implemented in DRM
side, so this change alone won't give any benefit. By the following
changes in DRM sides, the mission will be completed.

The HDMI jack handling reports the state change always via
snd_jack_report() whenever hdmi_present_sense() is called, even if the
state itself doesn't change from the previous time. This is mostly
harmless but still a bit confusing to user-space.
This patch reduces such spurious jack state changes and reports only
when the state really changed. Also, as a minor optimization, avoid
overwriting the pin ELD data when the state is identical.
