Comment 84 for bug 496616

Since the problem is apparently re-sampling related, I decided to give the following a go:

Keep the 'resample-method' at 'speex-float-1', and changing the line

; default-sample-rate = 44100

into

default-sample-rate = 48000

Forcing pa to use a 48k resampling rate. To my amazement this works.
This should result in an higher cpu usage when playing music with a 44k1 sample rate, but video playback is possible again using gstreamer.
