This should be completely irrelevant with the current audio code in
trunk. There should be no need to run iecset externally, and looking
at your log, it properly does so in mythtv.

If you do have to call iecset outside of mythtv to get audio, then
there's either a bug somewhere, or you haven't configured your audio
properly (e.g. didn't use one of the device automatically detected by
mythtv), which can happen if you simply upgraded to trunk without
editing the audio settings
