Right, so it appears the cause is rtkit failing. Still, pulseaudio
should not hang when rtkit cannot start.

As a workaround, you might try disabling high-priority and
realtime-scheduling in /etc/pulse/daemon.conf (although that will
probably give you suboptimal performance).

Could you please report this bug upstream at

Ah, I was wrong, it ~hangs (actually it waits 25s for every call) in 
rtkit_make_high_priority, when it calls 
dbus_connection_send_with_reply_and_block 
and it happens because rtkit fails to start :(

Sorry, I forgot to answer the arch & kernel questions :)
I'm using debian amd64 with debian-provided kernel (I'm way too lazy to build 
my own).

I strace it and judging from the log it doesn't seem to hang.

Wow, that hangs pretty fast. I'm guessing it hangs while trying to
acquire high-priority scheduling.

The initial bug did not report the architecture, which one it is? Are
you using a debian-provided kernel or a custom-built one?

Could you please (after installing pulseaudio-dbgsym), run under gdb
and present the trace of where it hangs? Note this is different from
the backtrace you already showed, as that is from the client, and we
want the one from the server.

For some time (~1month) pulseaudio doesn't work anymore on my system (after
I
upgrade my os ~1mounth ago). Until now I just removed it because didn't had
time to check. But today I've installed libpulse0-dbgsym and
pulseaudio-dbgsym
packages and I could trace (more or less) the problem.

As you can see it's hanged in context_autospawn, sadly I have no idea what
to
do next (besides removing it again) :).


This suggests the server is failing to start. Is there a pulseaudio process
running?(my guess is not) Could you start pulseaudio manually in verbose
mode to see what it says?

pulseaudio - --log-target=file:pa.log

And then please attach pa.log to this report

Saludos,

P.S. I tried to rebuild the packages from source, but it fails to compile it.
