[pulseaudio-discuss] pulseaudio daemon not responging

[Stefan Stefanov]

Ok.
Here is a report after simple debugging with "traps" like pa_log("test");
The call stack:

pa_alsa_sink_new -> alsa-sink.c
pa_sink_put(u->sink) -> sink.c
pa_assert_se(sink_set_state(s, PA_SINK_IDLE) == 0) -> sink.c -----> it
hangs here.

I'll continue debugging tomorrow.
