I have the same problem in 0.27 with missing audio after transcoding.
But.... sometimes I can transcode and audio still works. I think I've narrowed it down to the scenarios below.
WORKING AUDIO -
1. mythtranscode with lossless mpeg2 and honor cutlist
2. mythtranscode with mpeg4 and NO cutlist

=========================================================================
I can't seem to get avplay to admit that there is no audio. But nothing comes out.
The only difference between this output and one where audio works is the "max_analyze_duration reached" message and that the audio stream says it is "2 channels".
