Hey! I do a little bit of recording using a condenser mic, mixer and my laptop. I use a cable that connects the 2 RCA ports of the mixer to the 3.5mm mic jack in my laptop, which worked fine. When I tried this with my new laptop (which has a combined mic/speaker jack), the audio I recorded had a lot of crackling/white noise. What can I do to fix this? Could I use a RCA to USB cable to record instead? Thanks in advance!
