Streams are detached when they are removed or moved away from a device, or when a filter device that they're connected to is removed or moved. If these cases overlap, a crash will happen due to "double-detaching". This can happen if a filter sink is removed, and a stream connected to that filter sink removes itself when its sink goes away. Here are the steps in more detail: When a filter sink is unloaded, first it will unlink its own sink input. This will cause the filter sink's input to be detached. The filter sink propagates the detachment to all inputs connected to it using pa_sink_detach_within_thread(). After the filter sink is done unlinking its own sink input, it will unlink the sink. This will cause at least module-combine-sink to remove its sink input if it had one connected to the removed filter sink. When the combine sink removes its sink input, that input will get detached again, and a crash follows. We can relax the assertions a bit, and skip the detach() call if the sink input is already detached. I think a better fix would be to unlink the sink before the sink input when unloading a filter sink - that way we could avoid the double-detaching - but that would be a much more complicated change. I decided to go with this simple fix for now. BugLink: https://bugs.freedesktop.org/show_bug.cgi?id=98617 |

HACKING:
In order to run pulseaudio from the build dir __OPTIMIZE__ should be
disabled (look at src/pulsecore/core-util.h::pa_run_from_build_tree()),
this can be done by passing "CFLAGS=-O0" to the configure script:
./autogen.sh
CFLAGS="-ggdb3 -O0" LDFLAGS="-ggdb3" ./configure
make
./src/pulseaudio -n -F src/default.pa -p $(pwd)/src/
