On ASRock's website on the motherboard drivers section, a driver for THX TruStudio is available. I have a Z77 Extreme 4, and I am wondering is this driver for an additional PCI-e sound card, or is this to upgrade the onboard sound? And would this tool require an upgrade once I download it to a pay version?
THX TS is a utility that works with your onboard sound solution.
