I am having BIG problems with Roon and Dirac (1.1. and 1.2)
The two dont play nicely together anymore after a Roon update a week ago.
Roon itself behaves very well alone. The same goes for Dirac 1.1. and 1.2, but together there is some really heavy noise over the audio, which is very very loud/annoying/unusable.
Playing audio with Dirac and A+ and PureMusic works fine.
Unfortunately, the Dirac update to version 1.2 has reintroduced this issue on occasion, even with power-of-2 set. It looks like the update has exacerbated any buffer issues such that power-of-2 only works around 95% of the time I would guess.
