I'm facing a problem with my new sound DAC+ standard.
I did every step mentionned in the configuration topic :
- add "dtoverlay=hifiberry-dacplus" in /boot/config.txt
- remove "dtparam=audio=on"
- configuring alsa by creating /etc/asound.conf file with the appropriate content
- update the Linux kernel
Then reboot the pi, a green led appears on the sound card when pi is starting.
i tried with sox and a 1000 sine wave, mplayer and wav file, and vlc, at each time the greens led appears, then keep lighting until i stop the process, but no sound...
The card is connected to a well-working amplifier via RCA connections.
Everything works fine with AV jack and HDMI outputs.
Here is my config :
Raspberry Pi 3B+ with last version of Raspberry Pi Desktop and Debian
