last night I installed last Volumio Version 2.773 on my Raspberry PI 3b+ and Volumio Virtuoso Subscription, and since that moment, I have no audio on RCAs on my DAC.
DAC is a HIFIBerry DAC+ Pro and it worked until last Update.
I tried Audio Jack as Outbut and it work.
I have no idea whats happen.
Only strange thing are this red alert on dmesg on Raspberry:

Some suggestion on wich log check and what test to do?
Many Thanks in advance
