Summary: [pulsesink] Introduces artefacts into sound
("scratchy" playback)
Classification: Desktop
Product: GStreamer
Version: 0.10.26
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: gst-plugins-good
AssignedTo: gstreamer-bugs at lists.sourceforge.net

Hi,
Compare the output of the following two audio pipelines:
gst-launch-0.10 neonhttpsrc location=http://colin.guthr.ie/bong.ogg !
decodebin ! audioconvert ! pulsesink
vs.
gst-launch-0.10 neonhttpsrc location=http://colin.guthr.ie/bong.ogg !
decodebin ! audioconvert ! alsasink
Both pipelines ultimately go via PulseAudio (as alsa is configured to go via
alsa-pulse plugin), but the former (pulsesink) pipeline produces identifiably
worse audio even on small samples like the above.
It's most noticeable at the start of the playback.
