It seems that the problem was not solved yet. I am a new customer with a Volumio Primo HiFi and I am also having this problem of lock/unlock from the coaxial out.
I did chose Primo for having a coaxial out to connect to a DAT machine for recording, so this is a very important issue, is there a timetable for a solution?
Related with this is also needed an option as other players have like ‘delay the start for x seconds’ (configurable seconds) for hardware synchronization. This way the DAC or receiver machine can start without cut the first second (or part of it) when starting a song.
Thank you
