As a search you give the notion "Bass". See picture below.

After successful search you land with "APU" and see on the right side the entries
"CreatePhantomBass" and "CreateCenter"
The search for "bass" has taken there us purposefully here.
Change the active DWORD entries of "CreatePhantomBass" or
"CreateCenter" of "0" in "1" to activate the required loudspeaker.
Then you finish regedit and do a PC to restart.

After PC restart, check again with NV Mixer if 5.1 loudspeakers entry is now enabled.
