Audtion won't record - playhead jumping

I'm having a v annoying problem with audition. When I hit record the volume bar shows an inital spike, and then drops off. Nothing is recorded except from a vague crack at the start, and the playhead jumps ~1s at a time. It also seems like what is recorded is a LOT shorter than what I try to record (if I record 10s of me talking, for example, Audition turns that into 2s of audio)

I've tried different microphones (including my laptop default), all of which work on Audacity, but all have the same problem on Audition. I've tried in both waveform and multi-wave, but neither work. I've checked that the sample rate on preferences is the same as that of my microphone and it is. I'm stuck! Any advice/suggestions?
