I want to upgrade my sound for my system because I recently bought analog Razer Carcharias and found out that my motherboard wont play any sound if the green jack is connected in the rear but if I plug in a 3.5mm microphone jack that does work and the front plugs do work for sound. This happens with my other headphones so I know it's a mobo problem not a headset/headphone problem. Because it was brought to my attention, I decided to upgrade the sound of my system.
So, I was wondering if I buy a sound card like this one will it allow my headset to use 5.1 or 7.1 simulated surround sound and/or make the sound noticeably better? Also will a sound card improve the quality of the sound from the mic if it is connected?
Or should I just get a sound processor and connect it to the motherboard and headset since my motherboard already has the digital optical (surround sound) input in the back.
I'm willing to spend around $80-$90 to improve the sound of my system. I just want to improve the sound with 5.1 or 7.1 so I have a better experience in games, watching movies and listening to music.
Any help or feedback is appreciated and thank you for reading.
