No audio output on RPI after a period of idle time

[pantherale0]

After say 12+ hour of idle time, sendspin in daemon mode does not appear to actually play any audio until a restart of the service is done.

The only logs I've got are (the session on Mar 31 at 11:57 is what we are interested in), I'm showing some other logs so you can see it "does" work after a reboot:

I don't know if this is an issue with MA or not, but no other players have this problem and I can go back to a pretty old version of sendspin-cli and the issue goes away (1.x)
