I follwowed all instructions. At then end, I right clicked to select "Scan
for hardware changes", pointed to my CD with nvidIa audio drivers, and the
wrong C-Media driver reinstalled itself as before. Only cleanup glitch was I
could not delete reference in PCI/DeviceDesc: C-Media (Reg_SZ) and also Mfg
; C-Meica (Reg_SZ). Am I missing something???
