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
==== output from avplay for transcoded file with audio working (mpeg2 trimmed
by cutlist) ====

Note the audio stream above just says "stereo".
MISSING AUDIO -

=========================================================================
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".

Title:
after upgrade to 0.27 transcoded files no longer have audio
Status in “mythtv” package in Ubuntu:
New
Bug description:
recently upgraded from 0.25 to 0.27 on Ubuntu 12.04.1 LTS
among a few other issues, I have noticed transcoding doesn't work
properly any more
tried it four or five times now, with different audio options selected
in the frontend and also with different audio options on the "Low
Quality" transcoder configuration in the backend
no matter what I try, every time I transcode a recording, the
resulting file has no audio (I have confirmed by manually playing the
nuv file in vlc)
here is a log:
