 Encountered some issues in GST-pulse when using gnome-sound-properties and
 gstreamer-properties. Not sure how to explain them as i'm quite a novice,
 so i'll just attach the output of gnome-sound-properties --gst-debug-
 level=3 and hope its self-explanatorly.

 The symptoms being: If I select 'pulseaudio sound server' as my sound
 input with my usb mic set as the default source in pulseaudio and press
 test, it plays the microphone output for a fraction of a second and then
 quickly degrades, and then is silent.

 and i get a series of output similar to:
 {{{
 0:00:03.501275672 11042 0x84fe3b0 WARN         baseaudiosink
 gstbaseaudiosink.c:919:gst_base_audio_sink_skew_slaving:<autoaudiosink0
 -actual-sink-pulse> correct clock skew -5963085 < -5000000
 }}}

 Talked to some of the folks in #gstreamer on freenode about it and they
 had the following to say:


 {{{
 <wtay> rikai, yeah, something with pulseaudio and latency, it needs fixing
 at some point
 <rikai> wtay, ahh, so its a known issue then?
 <wtay> rikai, yep
 <rikai> wtay, any chance you could point me in the direction of the bug
 report? I'd like to keep tabs on it.
 <wtay> rikai, there is no bug report for it yet
 <rikai> ahh, so its a new issue too, then? That explains why it just
 started happening recently.
 <rikai> so, is the problem gstreamer-side or pulse side? i'd think it'd be
 in gst-pulse, which is gstreamer side, correct? Sorry for asking so many
 questions, i just want to know where i should follow any progress and
 such.
 <wtay> rikai, pulse side, likely. I think the gstreamer side should do
 things right..}}}
