That probably happens due to excessive CPU use in the IO thread. It's not known what causes the high CPU use, but the discussion revealed some definite shortcomings in PulseAudio when HDMI's underlying hw device is hw:x,0. There are two bugs: 1) PulseAudio assumes that if the front:x device doesn't work but hw:x,0 does, then hw:x,0 is an analog stereo device. 2) PulseAudio assumes that HDMI devices are always mapped to certain hw:x,y devices, the first one being hw:x,3. When this assumption doesn't hold, jack detection and ELD reading don't work. For the first bug, I propose trying hw:x,0 for analog stereo only if everything else fails, so if e.g. hdmi:x,0 is successfully opened, hw:x,0 won't be used. For the second bug, I propose removing the hardcoded device numbers, and instead query the device number from an open PCM handle. That's not reliable for all PCM devices, but Takashi expects it to work for HDMI devices. It's not obvious what would be the best way to modify the profile and path configuration syntax to support the new features. I'll prepare a more detailed proposal when I get around to it. My impression is that the HDMI LPE driver will be widely used, so I think this should be fixed with high priority (I'll mark this as a release blocker).

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.

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.

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.

Do you really mean ~/.etc/pulse/, or do you mean /etc/pulse/? I haven't seen anyone replacing ~/.config with ~/.etc, but it wouldn't be impossible to do that. If you meant /etc/pulse/, and ~/.config/pulse/ doesn't exist, maybe pulseaudio is running in the system mode. Is this some kind of an embedded distribution? What does "ps aux | grep pulse" print?

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.

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, 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.

I'm not familiar with the kernel code, unfortunately, so I can't really provide further pointers. If module-card-restore sets the card profile to "hdmi-stereo" when it's unavailable, PulseAudio will keep crashing if realtime-scheduling is enabled. Instead of patching PulseAudio, you can just remove module- card-restore from /etc/pulse/default.pa while testing.

I didn't notice this question until after sending my previous comment... The status of all jacks for an alsa card can be checked with this little script: while read -r line; do amixer -cX cget "$line"; done <<< $(amixer -cX controls | grep Jack) Replace the two X's with the card index.

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.

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.

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).
