Status changed to 'Confirmed' because the bug affects multiple users.

Besides this Whoopsie catch of pulseaudio crashing, the result is that audio doesn't work at all on the system. Settings -> Sound shows no options for the output or input devices, the "Test" button says to click on a speaker to test it but then shows zero speakers, just the icon of a person, etc.

I am happy to try daily builds or patched versions on this motherboard if someone wants to try to debug it.

(Also, comment #7 says "tracking in (url)" but I as an ordinary user don't seem to have access to that URL. It just shows me a graph of all error reports for all releases. So I can't see if y'all have a workaround that I could try, or want people who get this error to run some diagnostic or anything...)

[John Gilmore (gnu-gilmore)]

Just for fun I tried to start it manually.

$ pulseaudio --start --log-level=debug --verbose
D: [pulseaudio] conf-parser.c: Parsing configuration file '/etc/pulse/client.conf'
D: [pulseaudio] conf-parser.c: Failed to open configuration file '/etc/pulse/client.conf.d/01-enable-autospawn.conf': No such file or directory
E: [pulseaudio] main.c: Daemon startup failed.

And whoopsie pops up with the same old crash.

[John Gilmore (gnu-gilmore)]

I forgot to note (and the attachments don't apparently say) that I am also running this on a Gigabyte Aorus GA-AX370-Gaming 5" motherboard. I have an AMD Ryzen 7 2700 Eight-Core Processor,
and 16GB of DRAM. I'll enclose dmesg output so you can see what audio chips the kernel found when booting with this 20.04 beta kernel (Linux version 5.4.0-21-generic).

Also will include syslog version of dmesg output from an Ubuntu 18.04.4 boot in which the sound works fine.

[Sebastien Bacher (seb128)]

Could you try if https://bugs.launchpad.net/ubuntu/+source/pulseaudio/1:13.99.1-1ubuntu2 fixes your issue?

[John Gilmore (gnu-gilmore)]

With the -1ubuntu2 package, I no longer get a crash dump, but the audio is still not working. pulseaudio is aborting. Here is what is in syslog from bootup:

Comment #13 appears to be a new bug. Please open a new bug for that by running:

  ubuntu-bug pulseaudio

and mentioning:

  Apr 18 01:13:10 shh pulseaudio[1443]: E: [pulseaudio] alsa-ucm.c: Assertion 'jack' failed at modules/alsa/alsa-ucm.c:2158, function device_add_hw_mute_jack(). Aborting.

[John Gilmore (gnu-gilmore)]

OK, that's bug #1873630.

We don't actually know that this current crasher bug is correctly solved by the above patch, since pulseaudio is not yet working. Perhaps the new bug was there all along, but perhaps it was introduced by this patch being an incomplete fix.

[John Gilmore (gnu-gilmore)]

I ran the software updater and noticed that it installed a new pulseaudio:

pulseaudio:
  Installed: 1:13.99.1-1ubuntu3
  Candidate: 1:13.99.1-1ubuntu3

After rebooting the system, I'm running this version.

You will be happy to learn that pulseaudio doesn't crash with this version, and it shows sound devices in Settings -> Sound, and the speaker test actually plays (once I picked Line Out rather than the default which was Speaker -- my chassis doesn't have a speaker).

I am even able to play mp3 and flac music in Totem. I think it's fixed! Thank you!

[Sebastien Bacher (seb128)]

Great, thanks for testing, closing the bug!
