I recently purchased Audio Kontrol as my soundcard to replace my Numark IO and I am having some troubles with it. I have pinpointed that if I use the Numark IO I get low latency and no issues. When I go to use the Audio Kontrol, I can play one track with no issues but as soon as I cue up another and start to play it, I get a cracling noise (and the CPU bar starts to move to mid range). I have tried everything to get the crackle to stop (all the tips and config from NI, setting the latency to every setting available) nothing works. The AK is used so could it be that there is an issue with the device itself? Thanks in advance for any help because I am stuck!
