No audio when playing MPEG TS with MPEG2 video and AC3 audio

Created attachment 141673 [details] Debug output I'm using playbin2 to play an MPEG transport stream and while the video plays fine there is no audio. The same audio and video tracks play fine when I use a program stream instead.
Could you make a sample available somewhere? Possibly even the first megabyte would be sufficient (and could be attached) and can be obtained with 'head --bytes=1000k foo.mpg > head.mpg'.
This is coming from a multicast stream so I don't have an file to upload. I used VLC to save the stream to a file but I was not able to play the saved files at all using GStreamer. If you would like me to record the stream differently let me know and I can make those files available. http://machintosh.net/mpegtssamples/sample.ts -- This is recorded with the MPEG TS encapsulation method http://machintosh.net/mpegtssamples/sample-1000k.mpg -- This is recorded with the MPEG TS encapsulation method and Dump raw input selected http://machintosh.net/mpegtssamples/rawstream.mpg -- This is the same as above except longer.
