Soundflower + AU Lab + Mavericks results in incessant clicking

Soundsiphon solved it for me as well. You do not need to buy the pro version, because the capturing of whole system audio (which means no specific application like safari needs to be selected as an audio source) is for free. :-)

My setup: soundsiphon as default system audio device:

any Audio player/source on OS Yosemite -> AU Lab 2.2.2 (IN soundsiphon -> Waves GEQ -> OUT FiiO DAC:

Sorry for the german screens :-)

I fixed the problem permanently. 0 clicks 100% of the time.

I have macbook air mid 2013, OSX Yosemite AU Lab 2.3.1 Sound syphon http://staticz.com/soundsiphon/

Sound siphon is a replacement program for soundflowerbed. It does the same job. i think its free? the demo is running now but it doesn't seem to tell me days remaining.

Im going to go spread the word now.
