Sorry, I just discovered yet another "Mic Boost" control in the playback section in alsamixer (the others were in the capture section). Changing this now gives me:
Node 0x18 [Pin Complex] wcaps 0x40018f: Stereo Amp-In Amp-Out Amp-In caps: ofs=0x00, nsteps=0x02, stepsize=0x4f, mute=0 Amp-In vals: [0x02 0x02]
Strange.
