Hi,
I'm using linux kernel 4.6 on a T460 thinkpad (Debian jessie+backports).
Sound works fine with the internal speakers and the headphone port on the
T460. However, the headphone port of my Ultra Dock docking station does not
work, i.e., I don't hear anything. Playing around with mixer settings via
alsamixer did not help. Any ideas?
