   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][1]https://www.linuxquestions.org/questions/slackware-14/cu rrent-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][2]http://git.alsa-project.org/?p=alsa-...792dc809c908cc    [3][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 References    Visible links    1.
