Here's another screenshot of all my settings, hopefully someone can help with some suggestions

Basically, for my sound settings, I only get sound out of the "Speakers, Audio GD" and the top Digital Audio (S/PDIF) options. The "Speakers, Audio GD" option comes out from USB and is capped at 24bit 48 khz, while the "Digital Audio S/PDIF" comes from my optical cable and is capped at 24bit/192khz. I get no sound whatsoever from the TX1 and lower SPDIF options.
I'm assuming that my firmware 7 got flashed correctly since my subversion number is the same as the one in the audio-gd video when he flashed firmware 7. Could it be the usb32 driver be the culprit for my problems? I'm basically just running the setup file in the usb32firmware2.0 rar, "however when I choose the driver to install, the only box that's there say 1.0". Am I somehow installing the wrong usb32 driver? I tried to post up as many of my findings as possible, really hoping someone could help solve my problem as I would really like to get this thing fully working. Sorry for long post!
