I don't understand how we're getting two instances of this crash in version 1:11.1-1ubuntu7.3.
It sounds like either someone built their own package by the same name, or errors.ubuntu.com is not grouping the crashes correctly. I say this because the fix does: +++ pulseaudio/src/modules/alsa/module-alsa-card.c @@ -625,7 +625,8 @@ static pa_hook_result_t card_suspend_changed if (card->suspend_cause == 0) { /* We were unsuspended, update jack state in case it changed while we were suspended */ PA_HASHMAP_FOREACH(jack, u->jacks, state) { - report_jack_state(jack->melem, 0); + if (jack->melem) + report_jack_state(jack->melem, 0); } } Yet errors.ubuntu.com is saying it is still crashing due to a NULL melem: report_jack_state (melem=0x0, mask=mask@entry=0) card_suspend_changed That NULL should be impossible with the patch. I think most likely errors.ubuntu.com is grouping similar assertions in mixer.c:929 incorrectly. And it only shows the full symbolic stack trace from some older instance of the crash -- not the ones from version 1:11.1-1ubuntu7.3. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1663528 Title: pulseaudio assert failure: pulseaudio: mixer.c:929: snd_mixer_elem_get_callback_private: Assertion `mixer' failed.

Just watch errors.ubuntu.com to check for recurrences. [Regression Potential] Low. The fix is already in PulseAudio 12 so has been used in Ubuntu 18.10 and later for a year so far. [Other Info] SRU sponsorship tracked in bug 1556439. [Original Report] Sidenote: Imediatly got that crash after the apt-xapian-index one ( lp:1663524 ); does not know if it can exist a possible relationship between them. Got an other crash, and that time 'sound' is fully lost (pulseaudio not reloaded). Wonder if lp:1662860 can be concerned.
