The subwoofer is also at mono pin complex, are there any low pass filter for the subwoofer or vendor coeff need to be set ?
I don't know it, I guess there is no hardware filter, it will work with
the software low pass filter in the pulseaudio.

The ALC269 integrates five hardware equalizer bands composed of one low-pass filter, one high-pass filter, and three band-pass filters to compensate for mini-speaker frequency response
Do you mean alc255 does not have tbr hardware equalizer ?
