I have managed to get my  Digi+ Pro to play with mplayer, BUT there are two problems.

1) when I run mplayer from the command line I have to run sudo mplayer to get any output. Any way to get this to work in user-mode?

2) when I run the desktop VLC media player I have to menu select Audio | Audio Device | Built-in Audio Digital Stereo (IEC958) to get any output. (And if I play multiple songs, I have to do this for each song.) Any way to make the default selection be Built-in Audio Digital Stereo (IEC958) on start up and on every song?

  1. On most distributions you're user need to be in the audio group. But this can be different on the distribution your'e using.
  2. Unfortunately I can't say anything about VLC.

  I added my user (pi) to the audio group and It made no difference. My distribution is "Raspbian GNU/Linux 10 (buster)".

  I did, however, learn something significant. When I ran from the console as pi I got the same silence from the speakers, and no error message on the console, but when I ran as sudo, I got an error. Looking more closely, I discovered it makes a difference whether I have a monitor connected or not. With a HDMI monitor connected aplay -l will show cards 0, 1, 2 with the Digi+ as card #2. However, when I remove the monitor, the Digi+ becomes card #1. Changing /etc/asound accordingly restored output with sudo, but user mode mplayer remains silent.

  I just looked at the documentation and see that it shows "aplay -l" like this:

  card 0: sndrpihifiberry [snd_rpi_hifiberry_dac], device 0: HifiBerry DAC HiFi pcm5102a-hifi-0 []
  

  but mine says card 1 or 2 depending on whether my monitor is attached. I think that if I could reorder the list aplay displays to put hifi berry first, it could help both the mplayer and VLC issues. Any way to do that?

  You should disable onboard sound:
