Comment 31 for bug 1663528

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.
