     Â Â Â Hi,
        Â
     Â Â Â Since the upgrade to Alsa 1.1.7, I get a segfault at
     pulseaudio
     Â Â Â startup. This have been discussed and documented here :
     Â Â Â [1][1]https://www.linuxquestions.org/questions/slackware-14/cu
     rrent-fri-oc
     Â Â Â t-19-puseaudio-segfauts-4175640773/
        Â
     Â Â Â It seems that I found the origin of the bug : reverting these
     2 commits
     Â Â Â fixes the problem :
     Â Â Â [2][2]http://git.alsa-project.org/?p=alsa-...792dc809c908cc
     Â Â Â [3][3]http://git.alsa-project.org/?p=alsa-...5dc6e1594291e7
     Â Â Â Then no more segfault in pulseaudio when accessing the USB
     soundcard.
        Â
     Â Â Â Please could you fix it ?
        Â
     Â Â Â Regards
     Â Â Â jp
