   I found pulseaudio somewhat annoying although better now than before.   
   If the HDMI device was not on at boot, I had to killall pulseaudio and   
   it would then find the device.  Not so much anymore.  Pavucontrol is   
   very good for setting things now.

   Here, mpv.conf is in ~/.config/mpv/mpv.conf and:   
      
   #################   
   # audio settings #   
   ##################   
      
   # Specify default audio driver (see --ao=help for a list).   
   #ao=alsa   
      
   Also, I use smplayer as the mpv front end.  Very configurable if you're   
   not allergic to GUI.
