[Resolved] No sound while playing a CD

12

It seemed that you have a USB device plugged, that's why it has choosen hw:5,0.

The asound.conf is system wide and affects alsa sound configuration, which volumio does not use.

If in the future you add a usb audio dac or an i2s dac to the Pi, just rerun the audio reconfig.  It will choose i2c -> USB audio -> internal jack as priority.

Below sets the default alsa audio device, which needs to match with the device detected from "aplay -l"

defaults.pcm.card 0
defaults.ctl.card 0

The rest are configuration needed for upsampling and only used by NanoSound CD.
