Yes, that is unnecessary. Removed now,

Thanks, I've uploaded a new build #1412b (see post #1894) with this reduced logging.

No, but we did find a number of cases where high cpu caused underrun. You may see "underrun" in log if Pi Sink underruns, but you also get silence inserted when engine underruns without a message.

One issue is that the Sink thread is meant to run at higher (nice=-1) priority than other threads but that may not be allowed.
On raspbian I had to insert

Code:

*                -       nice            -1

/etc/security/limits.conf for this request to have any effect.
In OpenELEC I'm not sure if processes are allowed to decrease their nice level.

Not sure about decreasing the nice level in OpenELEC, though as everything runs as root I don't see why you shouldn't be able to do that.

In case its useful, this is the debug that appears when one Flac track ends and the next begins - there is a brief silence during the transition (CPU load averages about 25% at this time):
