I work for a small radio station that recently upgraded to a Late 2012 Mini to stream and archive our broadcast signal. (Technically, the machine sends a relay to our external Shoutcast hosting, people do not connect to it directly.) We don't use the machine for anything else. It remains locked away in a room with the equipment used to transmit our FM signal. Since switching over to the new machine, we've noticed that our stream develops a clicking sound after a while. (And by "a while," this can mean anything from "after a few hours" to "after a few days".) Similarly, the archived audio degrades in quality. After numerous things, we've narrowed it down to a possible power supply issue at the suggestion of a friend. (I know, how terribly unscientific!) He suggested that the crackling might not be audio related, but rather teeny power sparks causing interference with the audio. Since the 2012 mini uses a completely different power design than the previous models, has anyone encountered a similar problem? Would having Apple swap out the internal power supply even resolve this? Or is there something else that could be done?
