The alsa-info.txt for that Dell machine is at
http://pastebin.ubuntu.com/11667982/
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 funcional block diagram indicate equaliser is only connected to port D This mean only the internal speaker can use high pass filter
Do you mean your can hear high frequency from the subwoofer of alc255 ?
