Description Jan Alexander Steffens (heftig) 2011-06-27 18:03:40 UTC
qpaeq cannot be run, dies immediately with the following backtrace:

Comment 1 Colin Guthrie 2011-06-28 01:42:38 UTC
Have you got any equaliser sinks loaded? Does it still crash if you do? (It obviously shouldn't crash either way - just trying to narrow down the cause :D)
Comment 2 Jan Alexander Steffens (heftig) 2011-06-28 08:15:59 UTC
Indeed, loading module-equalizer-sink allows qpaeq to run.
Comment 3 Arun Raghavan 2011-06-28 09:16:19 UTC
Either we need to have qpaeq load the module, or error out gracefully.
Comment 4 Tanu Kaskinen 2011-07-20 09:02:49 UTC
Adding "triaged" to the whiteboard.

We don't currently have definitions for any whiteboard content. I think it would make sense to have such documentation. I'd define "triaged" as:

The root cause has been found. Now fix it!
Comment 5 Luis de Bethencourt 2011-10-28 04:39:41 UTC
Assigning it to myself, to dive into PulseAudio development. Please have some patience and give me a few days to have a patch ready.

Just needs to have graceful handling of missing dbus path saying "you haven't got module-equalizer-sink loaded, so bye"

Sounds great! It's been a while since your message - has there been any process? If not, that's perfectly fine, but I think in that case the bug status should moved back to NEW.
Comment 7 Tanu Kaskinen 2012-03-18 23:53:41 UTC
Back to NEW state due to lack of activity.
Comment 8 Colin Guthrie 2012-04-05 05:12:47 UTC
There is a patch for this (partially) on the ML:
http://thread.gmane.org/gmane.comp.audio.pulseaudio.general/12723

Therefore removing the "love" keyword.
Comment 9 Arun Raghavan 2013-11-22 10:25:43 UTC
I'm going to close this for now, since the patch has been merged and no further work to beautify qpaeq is currently happening. :)
