Hi, I have front panel audio connections on my desktop and there are two, one for line in and one for line out. I have Beats headphones that have a microphone on them and I'm wondering if I can use the microphone and headphone functionality at the same time. I am able to do this on my Apple devices. Also, can I use the volume buttons to change the volume in Windows 7? I've tried and it didn't work but is there a driver or hack? This isn't as big of a concern though.
