please if anyone knows how to fix this it would be so greatly appreciated. i went into my computer settings and set it to 'high performance mode' and nothing seems to change. I've been all over the net looking for answers, i'm not sure if its underruns because the under run counter is at zero and not increasing, changing the asio buffer size doesn't seem to have any effect, changing the multithread mixer and multithread generator have no effect. usually they both run perfectly fine when i use my primary sound driver, even when running powerful vsti like massive and nexus with multiple tracks. A quick tutorial for people who have got the new FL Studio 12 or have the older version and are still having this problem, on how to fix the crackling, laggy. Going down to 2+2 or 64 samples some crackles come in. The time critical priority is needed probably. I set also the ASIO settings in the Steinberg interface to low buffer size 96 (for low latencies near 10 msec). and its not just fl studio, i'm having the same problem in ableton. Today I found out, that I can have stable sound without heavy cracks and jumps by using the 2+3 U(async) setting in the POLAC ASIO.

the drums loop i already have set is crackling extremely bad, and when i start to play the guitar it sounds horrible crackling and popping and buffering. once i do this everything in fl studio starts to snap crackle and pop (no pun intended)and buffer horribly. in order to do this i have to switch my primary sound driver to the asio4all driver. I'm trying to record my acoustic guitar in fl studios,through the avid mbox mini interface. Increase it if youre still getting crackling. Go to Options > Audio settings and then drag the Buffer length slider up to about 100ms. i'm running Fl studio 11 producer edition on an hp elitebook 6930p, with an intel core 2 duo processor, 2.53 ghz, 4gb of ram, on windows 7 64 bit operating system. Basically, the buffer length needs to be increased which allows FL more time to process the mix when streaming it back.
