   Hi,

   Â

   Since the upgrade to Alsa 1.1.7, I get a segfault at pulseaudio
   startup. This have been discussed and documented here :
   [1]https://www.linuxquestions.org/questions/slackware-14/current-fri-oc
   t-19-puseaudio-segfauts-4175640773/

   Â

   It seems that I found the origin of the bug : reverting these 2 commits
   fixes the problem :
   [2]http://git.alsa-project.org/?p=alsa-...792dc809c908cc
   [3]http://git.alsa-project.org/?p=alsa-...5dc6e1594291e7

   Then no more segfault in pulseaudio when accessing the USB soundcard.

   Â

   Please could you fix it ?

   Â

   Regards

   jp

It does not appear like a correct change, because rec->slave is
initialized in previous lines (snd_pcm_open calls). Could you inspect
rec->slave in gdb ?

   Sorry, I have no more time to spend debugging :(

   Â

   Thus I guess that the true alsa maintainers will be much more efficient
   than me (I'm just doing quick and dirty hacking here).

   Â

   My XMOS USB soundcard now works with this workaround, please could you
   take a look at traces I posted in the discussion on LQ.org ?

   Â

   All the best

Here is the better fix:

http://git.alsa-project.org/?p=alsa-plugins.git;a=commitdiff;h=a4e7e1282c57a2f4e83afe9a4008042d8b4c5bb9

There was really a double pcm free, because:

  snd_pcm_ioplug_delete ->
    snd_pcm_close ->
      snd_pcm_ioplug_close ->
        a52_close() ->
          snd_pcm_close(rec->slave)

     Â Â Â Great !! looks like the real fix (I'm going to rebuild my
     version of
     Â Â Â alsa-plugins with it and let you know).

     Â Â Â Â Â Dne 23.10.2018 v 09:06 Hyperion napsal(a):
          Â Sorry, I have no more time to spend debugging :(
          Â Â
          Â Thus I guess that the true alsa maintainers will be
     much more
     Â Â Â Â Â efficient
          Â than me (I'm just doing quick and dirty hacking here).
          Â Â
          Â My XMOS USB soundcard now works with this workaround,
     please could
     Â Â Â Â Â you
          Â take a look at traces I posted in the discussion on
     LQ.org ?
     Â Â Â Â Â Here is the better fix:

     Â Â Â Â Â There was really a double pcm free, because:
          Â Â snd_pcm_ioplug_delete ->
          Â Â Â Â snd_pcm_close ->
          Â Â Â Â Â Â snd_pcm_ioplug_close ->

          Â           Â Â Â
     Â
          Â           Â Â Â Since
     the upgrade to Alsa 1.1.7, I
     Â Â Â Â Â get a segfault at
          Â Â Â Â Â Â Â Â Â Â Â pulseaudio
          Â           Â Â Â

     Â
          Â           Â Â Â It
     seems that I found the origin of
     Â Â Â Â Â the bug :
          Â Â Â Â Â reverting these
          Â Â Â Â Â Â Â Â Â Â Â 2 commits
          Â           Â Â Â fixes
     the problem :

     more segfault in pulseaudio
     Â Â Â Â Â when accessing the USB
