Thanks for your assistance. However, I'm not sure what to do with this
information exactly... I'm no expert. As to your question:
"The other output capable pin is node 0x1b, do the driver connected this
node to node 0x02 or 0x03?"
I checked with HDAAnalyzer, it seems like 0x1b is connected with
Node 0x0f [Audio Mixer] wcaps 0x20010a: Mono Amp-In Amp-In caps:
ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1 Amp-In vals: [0x00 0x00]
Connection: 1 0x0d
This seem to be stereo to mono down mix widget since node 0x0d is stereo

You have to check whether those amp out and mute switfch of the path

Connecting 0x17 with hdajackretask doesn't seem to work either. It adds
a third channel which is called "subwoofer" in the sound settings, but
when testing the subwoofer there is still no sound...

Hi Raymond,
I'm a linux noob and I have the same issue on my y700. Subwoofer doesn't
work. I see that you've posted some info about pins 0x0f and 0x17, but I
don't understand what it means. Is this some setting I can try on my
laptop to see if it resolves the issue?
