We need to cap node 0x0b at 0 dB for (your) ALC882_6ST_DIG quirk,
because your numsteps is greater than your offset to 0 dB, resulting in
distortion:
Node 0x0b [Audio Mixer] wcaps 0x20010b: Stereo Amp-In
Amp-In caps: ofs=0x17, nsteps=0x1f, stepsize=0x05, mute=1
Amp-In vals: [0x80 0x80] [0x80 0x80] [0x80 0x80] [0x80 0x80] [0x80 0x80]
[0x80 0x80] [0x80 0x80] [0x80 0x80] [0x80 0x80] [0x80 0x80]
Connection: 10
0x18 0x19 0x1a 0x1b 0x1c 0x1d 0x14 0x15 0x16 0x17
