My driver is version 4.47.0. It is the latest. However your device revision is different - v.0.52 vs my v.0.32.
Windows settings don't affect the sound probably because the FiiO's ASIO takes over.
I might change the balance in FiiO app eventually although this isn't ideal to me.
I have the old Q5, that's why revision number is different. That "revision" field actually refers to the firmware version, not some hardware revision.
What's under "Options" tab?
