            Bug ID: 776149
           Summary: alsasink: slave-method=resample corrupts audio
    Classification: Platform
           Product: GStreamer
           Version: 1.10.x
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: brain at jikos.cz
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

When using slave-method "resample" on alsasink in combination with udpsrc the
audio is broken. It sounds like the sound is "stretched" in time.

Interestingly in combination with audiotestsrc the audio sounds fine.

This is my pipeline:

gst-launch-1.0 udpsrc uri="udp://224.100.1.1:5004"
caps="application/x-rtp,media=(string)audio,encoding-name=(string)L24,clock-rate=(int)48000,encoding-params=(string)2,channels=(int)2"
multicast-iface="eth0" ! rtpL24depay ! audioconvert !
audio/x-raw,channels=2,rate=48000,format=
S24LE !alsasink slave-method=resample
