Unhappy Sound and WiFi issues

Hi guys,
I've searched and searched and couldn't find a fix to my problems.
Rooted and installed Team Win Recovery and happily flashed ROMs a few times. Flashed a ROM that is stock rooted but with WiFi issues, flashed the fix but still no WiFi. Got tired of no wifi so attempted the unroot and install stock unrooted but my cord somehow was disconnected during Odin flashing (literally the cord was still connected to the USB it just didn't register) of the .tar file. I flashed the .tar with a different cord and it worked but now I have no sound and still no WiFi. I've factory reset, DL'd the OTA update that showed upthinking that would solve the sound but didn't. Please help!
