I dont understand this Please explain ?

use advanced override mode to change the pin default of node 0x1a

With 0x16 put as not connected
it wont allow me to do the sound test see below

 # speaker-test -Dhw:0,0 -c4 -t wav

speaker-test 1.0.27.2

Playback device is hw:0,0
Stream parameters are 48000Hz, S16_LE, 4 channels
WAV file(s)
Channels count (4) not available for playbacks: Invalid argument
Setting of hwparams failed: Invalid argument

But I disconnected 0x15 and both left and right rear was coming out of the center Sub
