[PATCH 0/2] Fix beep notifications by Thinkpad's ACPI firmware

[PATCH 0/2] Fix beep notifications by Thinkpad's ACPI firmware

[Jarosław Janik]

In Comment 17 of the following bug report:
https://bugzilla.suse.com/show_bug.cgi?id=1228269
user tigerlily had complained about "audible blip on shutdown" on a
Thinkpad laptop, that led to a commit 4f61c8fe3520 ("ALSA: hda/conexant:
Mute speakers at suspend / shutdown"), which mutes speakers on system
shutdown or whenever HDA controller is suspended by PM. The
aforementioned "blip" is a feature, not a bug however - Thinkpad's ACPI
firmware uses short beeps / beep sequences as notifications in response
to various events (enter/leave suspend or hibernation, AC power
connect/disconnect, low battery, etc.); these can also be triggered by
writing to /proc/acpi/ibm/beep, see details here:
https://www.kernel.org/doc/html/v5.4/admin-guide/laptops/thinkpad-acpi.html#acpi-sounds-proc-acpi-ibm-beep
The firmware doesn't touch any mixer, so depending on current mixer
settings these beeps can be loud, silent or even muted completely,
whatever has been set by the user.

The patch in question interferes this badly:
- suspend/hibernate/shutdown related events are muted altogether because
  HDA controller is in suspend mode when they occur (or snd_hda_intel
  module has been closed in the event of system shutdown)
- other events work "randomly", e.g. you can hear AC plug/unplug beep
  if something is playing audio at the moment, otherwise the HDA
  controller is likely in suspend mode, so you can't hear anything
  (unless you disabled PM in snd_hda_intel module).

That said - let's revert this; this is what 1st commit does, the 2nd
commit is somewhat optional - it removes helpers introduced to implement
this muting, as they are no longer used.

PS. Don't forget to have this backported to LTS kernels, please.

[PATCH 1/2] Revert "ALSA: hda/conexant: Mute speakers at suspend / shutdown"

[Jarosław Janik]

Commit 4f61c8fe3520 ("ALSA: hda/conexant: Mute speakers at suspend /
shutdown") mutes speakers on system shutdown or whenever HDA controller
is suspended by PM; this however interacts badly with Thinkpad's ACPI
firmware behavior which uses beeps to signal various events (enter/leave
suspend or hibernation, AC power connect/disconnect, low battery, etc.);
now those beeps are either muted altogether (for suspend/hibernate/
shutdown related events) or work more or less randomly (eg. AC
plug/unplug is only audible when you are playing music at the moment,
because HDA device is likely in suspend mode otherwise).

Since the original bug report mentioned in 4f61c8fe3520 complained about
Lenovo's Thinkpad laptop - revert this commit altogether.

As it's a regression, it's OK for the first revert, but the function
is useful for other purposes and other devices, so I'd like to keep
it.  I'm going to apply only the first patch.

> PS. Don't forget to have this backported to LTS kernels, please.

This should be taken usually automatically as long as Fixes tag points
to the right commit.

Per reading the patch description, though, the behavior appears to be
pretty unreliable, as it depends on the runtime suspend.  We may
control the runtime PM better if we know that the beep must be
submitted; or it's even possible to runtime resume/re-suspend upon
beeping, too.  But it's maybe too complex than needed.

Takashi

You must have misunderstood that, this unreliable behavior is what
happens with your patch applied, once this patch is reverted everything
works perfectly fine (again). Perhaps the commit message should be
rewritten to indicate it more clearly, e.g. replace:

with

Hm, so the beep works even if the HD-audio device is runtime-suspended
before shutdown?  Also, beeping at suspend/resume works no matter
whether runtime-suspended or not?

Well, to what I recall - my (current) Thinkpad has never beeped on
shutdown, other than that - without your "extra muting" patch - yes -
beeping in every other circumstances works no matter if HDA controller
is in PM suspend or not; this is what I've got used to for many years of
using Thinkpads.

And one more thing - with your patch - beeping is not muted on my laptop
completely, you can still hear it if you are in a quiet room, it's just
very "weak".

Do you mean about the beep emitted via thinkpad_acpi stuff or the
normal beep via terminal etc?  The latter must work even with the
patch, but the question is only about the former.  And that's the case
for the shutdown beep tone.

You can pass snd_hda_intel.beep_mode=0 option to disable HD-audio
beep, verify the device being runtime-suspended, and check whether the
beep via thinkpad_acpi still works (after reverting).

It might be because there can be two routes of beep tone; one via
HD-audio and another internally.

Yes, I meant beeps emitted by ACPI firmware and I'm not confusing them
with beeps generated by linux console - as you said - the latter work
fine no matter if your patch is applied or not, the former only work
fine if that patch is reverted.

BTW. The ACPI beeps we are talking about are not emitted by
thinkapd_acpi module, but by ACPI firmware; you can take a look at how
thinpad_acpi handles writes to /proc/acpi/ibm/beep - it doesn't make any
beep itself, it just injects some "fake" ACPI event - and beep is
generated by laptop's firmware in response to that event (the
terminology here might not be too good, because my knowledge of ACPI is
rather modest).

Anyway - with that being said - when it comes to the lack of beep on
shutdown on *my* laptop - this must be because of *my* laptop's APCI
firmware just doesn't  emit beep for this specific event.

Yes, that works.
I've even had another test - with patch applied I increased power_save
param in this module to 3 seconds and now:
- when I unplug AC - there is no beep, because device is PM suspended
- now I hit Tab in bash on linux console, kernel emits beep and keeps
device awaken for 3 more seconds - so I quickly unplug AC - there is a
beep, then wait ~3 seconds and plug it back - no beep now. That shall
prove that our understanding of what's going on is OK.

For checking the runtime-suspend, at best check the sysfs file entry.
e.g. cat /sys/bus/hdaudio/devices/hdaudioC0D0/power/runtime_status

And, I see that Conexant codec doesn't have the beep generator but
it's only passthrough.  Then beep_mode option doesn't change
anything, but the "Beep" mixer volume/switch may influence on the
behavior; not only the beep volume but also the runtime-suspend
behavior.  You can try adjusting the volume/switch if it influences on
anything.

In anyway, you can try unload pcspkr module as well.  This is the
Linux input device for the beep in your case.  (For Realtek codecs,
there can be additional beep input device driven by HD-audio codec
itself, and that's managed via beep_mode module option).

Without pcspkr, the beep from the terminal shouldn't work -- unless
it's handled by the sound server like pulesaudio.  And, if I
understand correctly from your description, even without pcspkr, the
firmware beep should keep working.

As you see, the simple beeping stuff is really complex due to its
history.  Although it's a legacy feature, a few people still love it,
hence it can't go away soon :)

OK, so - just to be sure - I verified my assumptions about PM state of
HDA controller when "nothing interesting is happening" (suspended) and
for a short while after I generate a beep on a console (active) - so not
a huge surprise here :)

OK, so (again - just to be sure) - I understand that you are going to
revert that patch this is all about (no more tests or whatever needed

A beep sound triggered via the input beep device -- the one from
HD-audio driver, not from pcspkr -- does resume the runtime suspend.
So it's no surprise that it works.

OTOH, a question is rather the other route -- the beep via pcspkr
driver -- if this beep still works while the HD-audio is runtime
suspended: that's the interesting point.  Could you check that?
You can figure out which input device corresponds what, and try to
trigger directly there.

Also, one more question is whether the beep tone persists if you mute
the volume on the HD-audio (e.g. set "Speaker Playback Switch" to
off).  The beep tone at shutdown should be gone in this state, too.

Beep via pcspkr module works fine without your patch - regardless of
current PM state of HDA device; with your patch applied - the beep is
very quiet if HDA is suspended (same as with firmware generated beeps).

pcspkr generated beeps are immune to every mixer/switch setting except
for "Master Mute Switch", which mutes them completely (i.e. they are not
very quiet, they are gone). And again - this is the very same as with
firmware beeps; that would mean that both (firmware's and pcspkr's) are
using PIT to drive "PC Speaker".

Already there by now, thanks!

So, if the HD-audio Master volume influence on the beep output of
pcspkr, it means that it's flowing over HD-audio, likely there is some
analog-input loopback.

Could you give alsa-info.sh output?  (Run with --no-upload option and
attach the output).

If there is a mixer widget there, one of input pins might correspond
to the analog beep input -- even if the pin is marked as unused.

Thanks.  So this codec chip has no analog input mixer unlike Realtek.
Hmm. 

I'm not sure whether I already asked it: did you try to turn on/off
"Beep Playback Switch" (i.e. mute/unute "Beep" mixer element)?
It should control the digital beep of HD-audio's own beep input
device, but this might be also related with the internal beep from the
Lenovo firmware (and the output of pcspkr input device).

And, judging from the fact that "Master" volume influences on the beep
sound, it also means that the sound is routed to DACs -- for Conexant
codecs, Master is a virtual control just changes both Speaker and
Headphone volumes/switches, and both Speaker and Headphone controls
are tied with the Audio Output widgets.  You can check whether the
beep tone volume from pcspkr or Thinkpad ACPI is also controlled via
Speaker and Headphone mixer volume and switch.

Both "Beep" mixer and mute switch don't affect beeps generated by ACPI
firmware (and pcspkr module for that matter)

The volume of beeps from firmware and pcspkr is fixed, it's not changed
by any available mixer setting; the only thing that affects those beeps
is Master Mute Switch, which mutes them both on the speakers and on the
headphones.

Hm, that's odd.  At this moment, do you hear from the speaker?  Or
Speaker Playback Switch is off?

The speakers are completely silent once you connect headphones,
regardless of Speakers Volume / Mute Switch settings.

Even if you turn off "Auto-Mute Mode"...?  If yes, check the widget
NID 0x10 and 0x1f in the codec proc file
(/proc/asound/card*/codec#*).  The former should have the output amp
value like 0x40, and the latter should be pinctl 0x40 (output).
You can override the values directly via hda-verb, too.

Yes, speakers are always silent when headphones are connected,
regardless of Auto-Mute Mode and even if Speaker Mixer is set to max and
unmuted (which translates to 0x40 for NID 0x10 in my
/proc/asound/card0/codec#0).
When it comes to Pin-ctl of 0x1f - it is "0x40: OUT" as you said it
should be, unless Auto-Mute is enabled and headphones are connected
(it's 0x00 then); but it doesn't change anything - if you plug
headphones - speakers are quiet.

Aha, that's an interesting information.  Then basically Auto-Mute Mode
control is useless on your machine, and can be omitted.

Usually: yes. But a quick reminder: it also might be silently dropped.

If you want to ensure it's backported, a stable tag is a must:

Ciao, Thorsten
