As mentioned now we seem to have stopped the dropout issue - have moved it back to the AAC 320kbps stream today to just check. Just a whole bunch of stations not starting - who’s streams work fine on the Pro-Ject Stream box or if manually entered into VLC.
After changing back to the AAC stream - stopped at 11.32 GMT and 15.32 GMT - same problem - just shifted roughly 10 minutes later !! I’ll pop another set of logs over by email !!
Build a new ROCK last night, new hardware, fresh install. Bought it into work this morning, exactly the same behaviour with not being able to start a whole bunch of radio stations. Will leave it on to see if it does the twice a day hiccup.
