Headphone-Mix amp Gaming version

Ever wanted a gaming mix amp? well i did and i was asked to fork over 170+ Dollars. in the end i thought to myself, hey i can build of of these, how hard can it be. well now i want to share my journey with you.

this build has two sections, i guess. first is inputs to mix (not shown in pics) which then goes into amplification. obvious of course. the good stuff seems to be your getting what i think is a versatile unit. main purpose is for gaming mix amp which has line input (rca), mic, headset and also stereo 3.5 jack.

the amp section is based on a couple lm386 designs which i stripped down and modified so suit this application. it runs of a single 9v battery and currently in testing phase with usb power. usb power creates a large amount of hum and ticking noises which are not remedied by capacitor or voltage regulator. any ideas would be of great help.

what do you think?

I will be posting my schematics and pcb designs so they can be scrutinized. hope you guys contribute and share some ideas.
