Interesting.  I didn't know whether to blame the ffmpeg resync, a newish 
nvidia driver (390.25, IIRC) or my stream-mangling experiments.  I think 
it has always been triggered by starting playback of a modified HD 
DVB-T2 recording (aac/LATM, again IIRC).

I doubt that Myth has internal settings for it at present;  I have an 
audio devices widget in my task bar, and also in the KDE 
plasma-systemsettings audio devices screen.  It doesn't survive reboots.
