   Thanks for responding. With Henrik's help I found my config file.   
      
      
   I see in your conf file you do not define anything. That is   
   what I had by default and I got sound before upgrading my   
   system. Using mpv -ao help I see that I have options  pulse,   
   alsa, oss and others. I tried invoking mpv with the   
   options --ao=pulse (when pulseaudio was running) and got   
   no sound. Then, again when pulseaudio was running I tried   
   --ao=alsa, again no sound. Finally I tried --ao=oss, again no luck.   
      
   Then I stopped pulseaudio and repeated the three command line   
   options --ao=xxx, and again no sound. While pulseaudio was   
   running I brought up alsamixer and set the sound card to   
   my NVidia card. Then I ran alsactl store to save the setting.   
      
   All of the following experiments were run with pulseaudio off.   
      
   Still working with the command line I tried --ao=alsa:device=plughw=1.3   
   and mpv didn't start. I tried putting "" around the device stuff but   
   mpv still wouldn't start.   
      
      
   Then I tried putting the audio device setting in the config file.   
   Here is my command line:   
   mpv -fs --vo=gpu  --vd-lavc-threads=4 MOVIE.NAME   
      
   In the config file I tried:   
   audio-device=alsa/default   which had been commented out.   
   and then   
   audio-device=alsa:device=plughw=1.3   
      
   again neither of these resulted in sound.   
      
   mplayer seems to work regardless of whether pulseaudio is running.   
      
   I ran through all these options exactly as written while writing   
   this response. Nothing works.
