GL703GS here.
Since this PM (20-Mar-2019) ASUS Sonic Studio III lost control over audio output: EQ, Reverb and other enhancements do not work anymore.
I've seen Windows 10 got an automatic Realtek update, so maybe this corrupted something?
Already tried to reinstall Realtek drivers + Sonic Studio 3 + Sonic Radar 3 but didn't work: I'm stuck with standard audio settings and changes to EQ, etc. are ignored.
Others can confirm a Windows Update issue and Sonic Studio 3 enhancements not working anymore?
