Hello, I'm fairly new to vinyl and I'm having a bit of trouble. I recently got an AT-LP60 which I have connected to my laptop through an AUX cord to Line-in on my laptop. Through there, I have all of my audio default to going through my Blue Yeti USB mic through the headphone jack and into my ATH-M50x s. It's not pretty, but it works...only in my left ear. The vinyl audio only ends up going to my left ear in my ATHs. I have checked with multiple records, and the problem persists. With such a complex setup, I understand that there likely isn't one clear answer. What should I check to troubleshoot? Thanks in advance.
