The fact that I can *always* play with aplay /dev/dsp
says mixer settings, cables, everything along the path is guaranteed to be 
working (I've not tried aplay together with transcode - if THAT worked I'd go 
and scratch my head 
[for anyone reading this that does not apreciate shareing, this *must* fail, 
that is what pulse tries to solve]
Also lsof shows only transcode using the dev file, no transcode and usage is 
blank.
Time to try alternative hardware ...

Also strace does not show anything significant
