No sound from Volumio

Volumio 3 Issues?
I have been using preinstalled Volumio on a Allo Digione Signature bought in June 2021. For about six months connected to may Audio Note DAC 1 or alternatively to a Por-Ject DAC S box I had no problems. After an upgrade to Volumio I was unable to get any sound. I have reflashed Volumio on my Allodiginoe Signature with RiP B3 , but still no sound from the unit. I am not an expert , can anybody help me?. Many thanks.
