Hello. First of all, I just installed PAX 20K2_Auzentech_HTHD_RefCD3 2014 V1.00 and I would like for someone to please explain to me the difference from these to the official ones. I had the official ones on Windows 8.1 and now I have these also on Windows 8.1, both work the same (I think). Also, I have my headphones connected to the back of the sound card (because of buzzing sounds created on the front panel), but because of this I need to disconnect my headphones everytime I want to use my speakers (so that I don't have sound coming from two places). With headphone setting enabled on the console I only have sound coming through my headphones, but with speakers setting I have on both speakers and headphones. Is there anyway to disable the sound on the headphones when speakers setting is active, so I don't have to connect and diconnect the headphone jack from the back of my PC everytime I want to change from my headphones to speakers and vice-versa? P.S.: I would use the front panel since this issue doesn't happen there, but when playing games I have a buzzing sound, so my only option is to use the back of the card to plug my headphones. Thanks.
