pulsesink distorts audio in left channel

Please describe the problem: I use a Mac Mini core duo as my Linux system. It runs openSUSE 11,1. Since I upgraded to this release I noticed distortion in the left channel. It sounded like a cable problem at first. Then I noticed that only Amarok produced distorted sound and that playing the same stream with VLC did not produce the distortion. Finally I found that I can get rid of the distortion by switching to alsasink Steps to reproduce: 1. Play an MP3 stream with Amarok; 2. Play an MP3 stream with yauap 3. Play an MP3 stream with gst-launch souphttpsrc location=http://gffstream.ic.llnwd.net/stream/gffstream_w21a ! flump3dec ! audioconvert ! audioresample ! pulsesink Actual results: Clicking sounds in left channel Expected results: Undistorted sound in both channels Does this happen every time? yes Other information: gst-launch souphttpsrc location=http://gffstream.ic.llnwd.net/stream/gffstream_w21a ! flump3dec ! audioconvert ! audioresample ! alsasink plays the stream without this distortion. I found this out while listening to the new years concert from Vienna!
I've solved this problem. It was due to a pulseaudio bug: http://www.pulseaudio.org/ticket/358 Adding default-sample-format = float32ne to my /etc/pulse/daemon.conf file has solved the problem!
