If, before starting playback, you set the speed to a value over 1, no sound
will be output.

If you wait for a short time (I tried 100 ms) before doing that it works. If
you set the speed to a value < 1 it also works.

If you set the speed to a value over 1, start the sound, wait a little and then
change it, the program will crash.

so this works:

gst-launch -v filesrc location=test1.mp3 ! decodebin ! audioconvert ! speed
speed=1 ! alsasink

and this:

gst-launch -v filesrc location=test1.mp3 ! decodebin ! audioconvert ! speed
speed=0.9 ! alsasink

but this doesn't:

gst-launch -v filesrc location=test1.mp3 ! decodebin ! audioconvert ! speed
speed=1.1 ! alsasink


I suppose the plugin is trying to read ahead on data that is not yet available.
