I have a Lenovo Thinkpad X1 and I have it docked to a Lenovo Thinkpad OneLink Dock (http://shop.lenovo.com/us/en/itemdetails/4X10A06077/460/6D501EE899104FF9A362D739642CFC27)

It seems like for some reason, pulseaudio sees this dock as two devices, and has two different ideas about how loud the volume is.

PulseAudio thinks that your hardware supports a digital output via S/PDIF (in additional to the standard analog output via your headphone jack / speakers). I'm not sure whether that is true or not.

Could you post the output of alsa-info? I'm not sure how we can verify whether what we detect is accurate or not.

# If a device does not use the first PCM device for digital data, the device
# number for the iec958 device can be changed here.
