Yes, the HDMI output will be ignored in the sense that it won't be selected as
the default output, but a card will be created nevertheless (at least if we're
talking about the LPE driver - other hardware may just create HDMI ports on a
card that is shared with analog output, but I digress). If the computer doesn't
have any physical HDMI outputs, as I understood to be the case with Lenovo Miix
8, then it would be better to not create a card or ports for HDMI (and ideally
the HDMI stuff would already be suppressed by the kernel).

AFAIK we already have jack-detect for HDMI in newer pulseaudio + kernel combos,
if there is no external HDMI the i915 should not detect a HDMI calbe being
plugged in and pulseaudio will ignore the HDMI output.

What does the EDID contain when there is an HDMI output but cable is not
plugged in? If it's possible to distinguish the two cases of no HDMI output at
all and HDMI output with nothing plugged in, then it would be possible to
implement automatic ignoring of non-existent HDMI devices in PulseAudio. It
would seem more appropriate to do that already in the kernel, though.

I believe that all pulseaudio issues with LPE HDMI have been fixed in the
current pulseaudio master git branch as well as in the 12.0 prereleases (the
11.99.x releases).

I have been running these for a while now on various Bay Trail and Cherry Trail
systems while keeping realtime scheduling enabled without any issues.

There still is one remaining issues where audio streams are not automatically
moved away from the HDMI on HDMI unplug, instead they get paused. But that is
probably best tracked in a separate bug.

Tanu, is it possible to hide HDMI Audio output on devices without HDMI output?
For example on Lenovo Miix2 8 there is no HDMI. As far I remember it's
indicated by HDMI EDID that contain only zero, but in necessary I could double
check that.

Ok, so I won't be testing this then (since the patches are already applied /
resp. obsolete). Thank you for the update.

Tanu,

Thank you for all your work on this! I don't think I will find time to test
this before 2018 :), but I will definitely give this a try soonish.

Hans

It was reported that even with all patches applied, PulseAudio still was being
killed when unplugging the HDMI cable. I have now submitted a fix for this.

Here's the complete list of patches related to this bug that are not yet in
master:

Jack detection fixes:
https://patchwork.freedesktop.org/patch/181163/
https://patchwork.freedesktop.org/patch/181164/
https://patchwork.freedesktop.org/patch/181165/

Infinite loop fixes (only the first patch is needed, but if there are still
problems, the last two patches will make debugging easier):
https://patchwork.freedesktop.org/patch/195092/
https://patchwork.freedesktop.org/patch/195091/
https://patchwork.freedesktop.org/patch/195093/

After these patches there still remains the problem that PulseAudio doesn't
automatically move streams away from the HDMI sink when the HDMI cable is
unplugged. I plan to fix that as well.

I can confirm that these 2 patches:

https://patchwork.freedesktop.org/patch/187101/
https://patchwork.freedesktop.org/patch/187102/

Allow pulseaudio to run on Cherry Trail hardware without needing
realtime-scheduling=no.

Ah, if the pa changes fix the realtime issue they are worthwhile to have even
without them fixing hdmi, because currently the realtime issue breaks pa
altogether on Bay and Cherrytrail systems. I will start a Fedora pa
scratchbuild with these patches added and see if that fixes the need for
disabling realtime-scheduling.

As for the kernel-side issue causing hdmi audio out to not work, do any of the
kernel devs reading along have an idea where to start with debugging this?

Thank you for looking into this. So if I've understood correctly, at this point
this seems to be (mostly) a kernel bug, correct?

Is there an easy way to check the kernels view of hdmi being plugged in or not
without using pulse ?

Also do you perhaps know the code where the jack status for hdmi gets set so
that I can add some debug printk-s to the kernel there?

I've the feeling that the restore patches are mostly to avoid errors in the
log, do I need to patch my pa with these for further hdmi audio testing ?

--- Comment #41 from Tanu Kaskinen  ---
The log looks strange. module-card-restore says that it's restoring profile
"off", but then "hdmi-stereo" gets activated anyway.

Ok, I found the reason. The log message prints the wrong profile name.
module-card-restore is probably setting the profile to "hdmi-stereo" in
reality. module-card-restore shouldn't do that, because "hdmi-stereo" is not
available. The availability check seems to be missing.

I'll make a patch for module-card-restore. That should prevent the unavailable
"hdmi-stereo" profile from getting activated.

Of course, since you have HDMI plugged in, the expected result would actually
be that the "hdmi-stereo" profile would be available, but the kernel driver is
definitely behaving as if there was no cable plugged in. It's not just wrong
jack status being reported to userspace, the driver is actually refusing to
play any audio.

Sorry, I accidentally hit save, take 2:

Hi All,

So I've tried to get hdmi-audio to work on a cherrytrail device with Fedora 27
which contains a pulse version build with the necessary patches.

I noticed 2 things:
1) I still need to set "realtime-scheduling = no" in daemon.conf to stop pulse
from crashing

2) pulseaudio sees the hdmi as unplugged even after plugging in the hdmi (video
does get set up and shown on the monitor)

I'm attaching the output from pulseaudio -vv from the following test run:

1) start pulseaudio -vv on a cht device without the hdmi plugged in
2) start pavucontrol
3) plug in hdmi tv
4) See that pavucontrol still sees hdmi as unplugged (and playing audio to it
does not work)
5) kill pulseaudio -vv with ctrl+c

Regards,

Hans

In relation to LibreELEC, this is correct.

https://bugs.freedesktop.org/show_bug.cgi?id=103299 should not have been closed
as a duplicate of this issue and is unrelated (I've reopened it for that
reason).

It seems that nobody really knows what has changed in the 4.13 kernel that
causes this issue with Cherrytrail hardware, but it almost certainly isn't
anything to do with PulseAudio.

Ok, so you don't know what "~" means? It's an abbreviation for the home
directory. If your username is "phils", then "~/.config/pulse/" is expanded to
"/home/phils/.config/pulse/".

Ok, you're running pulseaudio in the system mode. I had a look at how LibreELEC
configures PulseAudio, and it seems to use systemd to start it, so run
"systemctl stop pulseaudio" as root. Then run "pulseaudio --system -vv" as root
and continue according to my earlier instructions to get the log.

I'm not sure this is a PulseAudio issue, though. LibreELEC seems to disable
PulseAudio's ALSA functionality, so I would expect that on LibreELEC you're not
supposed to use PulseAudio at all to play to HDMI. Maybe PulseAudio is used
only for bluetooth output.

I'm afraid that I don't know the difference between ~/.etc/pulse/ and
/etc/pulse/.

I just used the same syntax as used in the request to provide a log.

I only know that if I start from root then drill down to etc and then pulse I
can find the client.conf file.

ps aux | grep pulse returns the following:

275 root   0:00 /usr/bin/pulseaudio --system
817 root   0:00 grep pulse

The distribution is a form of Libreelec from Millhouse over at the Kodi forums.

I hope that this helps clarify things to some degree.

Thank you for the information Tanu Kaskinen.

The first command returned the error "Failed to connect to bus: No such file or
directory"

I then looked for the client.conf folder in ~/.config/pulse/ but there was no
folder of that name.

I did find one in ~/.etc/pulse/ but despite seemingly having root access, every
time I attempted to edit the file, error: 4 was returned and more research
indicated that the file is read only and so far I have been unable to find a
way to write the edited file in order to reproduce the issue and provide a log.

Can you attach the pulseaudio log (with debug logging)? To get the log, follow
these steps:

1. Disable automatic starting of PulseAudio. If your distro uses
systemd's socket activation to start PulseAudio, run

systemctl --user --now mask pulseaudio.service pulseaudio.socket

If your distro doesn't do that, put "autospawn = no" to
~/.config/pulse/client.conf.

2. Stop pulseaudio with "killall pulseaudio" (the previous systemctl
command might have stopped it already, though).

3. Start pulseaudio in a terminal with verbose logging:

pulseaudio -vv

4. Try to play something. If you hear nothing, then great, you successfully
reproduced the bug.

5. Stop pulseaudio with ctrl-c.

6. To return things back to normal, run

systemctl --user unmask pulseaudio.service pulseaudio.socket

if you masked the service before. And remove the "autospawn = no" line
from client.conf if you added it there.

Millhouse produced a new version of Libreelec (#1020b) with the patches but on
testing there was still no audio.

Ah, ok, I see this seems to be a problem specific to the surface3, so I cannot
reproduce.

Hmm, I did not know there even is a alsa-ucm package on Fedora, it seems
nothing requires this, so it does not get installed by default. Anyways this is
off-topic for this bugzilla. I will send you a mail about this.

kernel bug, see:

Do you have a ucm file for your SoC / codec combo? :

https://github.com/plbossart/UCM

mkdir /usr/share/alsa/ucm  and then copy all the *dirs* from that git repo
there.

I've tested Fedora 26's PulseAudio which includes this series of patches[1] and
the alsa-lib change from comment 23, and I can't get any output on the internal
audio anymore.

The HDMI output appears as unplugged on my system (the mini DisplayPort to HDMI
converter doesn't seem to work for video either in Linux, another problem), but
the internal audio just isn't there at all. Though that might be the current
upstream linus tree being busted :/

I haven't had proper reminders about the patch set, so I kind of forgot about
it. I plan to simplify the patches a bit soon.

I submitted the alsa-lib patch now. Let's see if it gets accepted...

Thank you for working on this.

I still need to apply https://patchwork.freedesktop.org/series/25656/ on top of
master to prevent PA from crashing. I saw that Arun was a bit concerned about
the patchset. Is the patchset still valid or there is anything else in the
working?

--- Comment #21 from Tanu Kaskinen  ---
I think it's a real fix. Not a nice fix, but the fact is that things will break
in PulseAudio if alsa defines "front" to be the same as "hdmi". Strictly
speaking "front" is allowed to be any device that has a front-left,front-right
channel map, but in practice it shouldn't overlap with other device
definitions, because PulseAudio needs to tell analog and HDMI devices apart.
There's no separate definition for analog devices, so PulseAudio assumes that
"front" is analog, and usually that assumption is correct.

I'll send the patch to the alsa developers. Thanks for testing!

Yes, in that case it works fine. Is this a workaround or a real fix though?

no-analog.patch

PulseAudio successfully opens the "front" device, which it shouldn't be able to
do. Now that I look at HdmiLpeAudio.conf, I see that it defines the "front" and
the various "surround" devices, which confuses pulseaudio, because pulseaudio
expects those to be analog devices.

I attached no-analog.patch. Look at the removed lines - if you remove those
from your HdmiLpeAudio.conf, does pulseaudio work then? If not, the verbose log
will again be useful.

pulseaudio SIGKILL-ed log

Also on my cherrytrail machine pulseaudio is being SIGKILL-ed at start. I have
described my setup here https://bugs.freedesktop.org/show_bug.cgi?id=102877

I also tried to apply on top of the latest master the patch in
https://patchwork.freedesktop.org/series/25656/ (the patch for the first bug
was already merged) and also imported the HdmiLpeAudio.conf configuration file,
unfortunately pulseaudio keeps being killed.

In attachment the log.

Any other test / hint / suggestion / patch to try? This is a really nasty and
annoying bug.

(Sorry for not responding earlier.)

Yes, you'll need to upgrade alsa-lib, or at least apply this patch to the
configuration that alsa-lib provides:
http://mailman.alsa-project.org/pipermail/alsa-devel/2017-February/117706.html

Even after that it's likely that pulseaudio will still get killed - if that
happens, please provide the verbose log.

I found that on Wyse3040, the name of output profile is 'analog-stereo'. Then
the proposed fix cannot be applied on it.
After changing /usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf, and
add 'query-hw-device = yes' in [Mapping analog-stereo] section, PA stop
crashing.
But I am wondering if there are any side effects for other platforms.

I met a similar issue that is pulseaudio keeps restarting (killed and
restarted).
The platform is Cherry Trail and the monitor is Dell P2317H (no audio).
Connection type is display port.

Try the patch in comment #4, but pulseaudio still restarts continuously.
The patch is applied to both pulseaudio 8.0 (Ubuntu 16.04 Xenial) and
pulseaudio 10.0 (Ubuntu 17.04 Zesty).

System configuration:
Platform - Dell Wyse 3040
Monitor - Dell P2317H
Connection - Display Port
OS - Ubuntu Linux 16.04/17.04
Kernel - 4.13

What is the expected behaviour with those patches? For me, on a Surface 3

crash, but I get no sound from the internal speakers when HDMI is not plugged

Yes, I think making the jack detection work is important. I understand this[1]
message from Takashi so that we should avoid using the device when the monitor
isn't plugged in, and for that we need working jack detection.

I sent a patch for the first bug:
https://patchwork.freedesktop.org/patch/152433/

The patch is simpler than I first thought: it doesn't change the configuration
syntax at all. It just moves the hw:x,0 handling from the analog-stereo mapping
to a new unknown-stereo mapping that is marked as a fallback, that is, it's
used only when nothing else works.
