What are you using for your audio output?  On Mythbuntu 16.04, I am
using SPDIF, and am having a persistent problem where something is
turning off the SPDIF output in Alsa.  If I run alsamixer and unmute
the SPDIF output, it works again.  Until the next time it happens.  I
have yet to work out what may be doing this, but it was not happening
with my Mythbuntu 14.04 setup.  Does that sound anything like your
problem?
