Very Low noise when recording sample w/ Audio DJ 4

Hey guys, I am trying to sample with my maschine. Unfortunately I get very low muffled sound on playback if any. I have tried everything. I have tried sampling both from my PC and my turntable via the audio dj 4 and still the same thing. I do get waveforms on my maschine hardware but upon playback oon the software there is none, and like i said the sound is very muffled. I have it set to ext 1 L+R. I have tried using both sync and detect and messed witht he threshold, stilll nothing. Any help at all would be very appreciated. I also have the SRc set as input not sampler, as I read in an older post, still not working

 

Ok I seemed to have fixed it but doing what I did won't help me when trying to sample from traktor timecode, at least I don't think so anyways...
I went and unplugged my in cable from one channel and pluuged in a rca going from my rec out on my mixer....this worked but the volume output was redlining in maschine unfortunately. I messed with the volume seetings in the audio 4 control pannel and nothing, but when i changed it to cd control it worked perfect. However I don t know how I am gonna sample with traktor timecode now. Is this the only way? Or am I going to have to get an audio dj 4 to do this and to sample 2 or more decks, cause I think I am sh*t outta luck here....hope someone can help.

 

Update:
after recording a few things the volume seems to just be a tad lower than I need it...any suggestions on how I can turn the volume up someway?
