Does this go away if you change your resample method to trivial? If yes, how have you built/installed PulseAudio? You had some questions about the requirement of the presence of libsoxr0 on IRC as well? I'm using the pulseaudio 7.0-1 package on Debian Stretch. It does not seem to have a dependency on lisoxr0 package. I am not sure whether this package is needed or not. I can reproduce it like this: Play some music with Rhythmbox or Spotify, then go to http://speeltuin.stubru.be/bevergem/ and click on one of the sound clips. Thes sound gets distorted, and a few seconds later audio stops completely and Pulseaudio crashes. Could you also answer my first question about switching to another (non-soxr-based) resampler? Pulse on debian doesn't seem to be build with soxr atm see: https://buildd.debian.org/status/fetch.php?pkg=pulseaudio&arch=amd64&ver=7.0-1+b1&stamp=1446593504 checking for LIBSOXR... no Then I am suprised that the soxr resamples appear in the output of pulseaudio --dump-resample-methods. I guess that's a bug? Then also should not an error be printed in the logs when an invalid resampler method is selected? With trivial resampler it does not seem to crash. The missing check is fixed now, and will be in the next release: http://cgit.freedesktop.org/pulseaudio/pulseaudio/commit/?id=daf326a9e4dcd5c9d716e6c2fc0a07b99f6ee1c0 |

I'm experiencing a segfault in pulseaudio, which seems to happen when a notification sound by GNOME or Skype is being played while I'm watching a movie clip using the Flash plug-in in Firefox.
