Hello, I'm having some trouble having my speakers and headphones working together. In my prior setup, I've always had my Macbook Pro Line-Out connected to a set of speakers who allowed for my headphones to be jacked into it. I had no problems with this setup as it allowed me to use either one. Now, I bought a new Logitech G35 headset which has a USB end as opposed to the 1/8" jack, and I have to switch between the speakers and headset via Settings > Sound > Output. Is there a way to prevent this from happening?
