Hi,
I am having problems with the sound when the laptop is docked on Thinkpad pro dock. I'm currently using external monitor through displayport. "pavucontrol" tells me the displayport is not connected. Through, mini displayport on the laptop, however, the sound works just fine. I am just having problem with the sound via the docking station.
Before using Arch, on windows, I had this issue and solved it by installing a Intel display driver.
Have anyone encountered this problem while using Thinkpad dock?, specifically when using external monitor via HDMI port or displayport.

I've the same problem with a Ultra Dock. This is a BUG because the problem exists since kernel > 3.16

So, there is no way to fix the problem unless Kernal is fixed?

I had the same problem, that's what worked for me:
Create a file /lib/firmware/x250.fw:
[codec]
0x10ec0292 0x17aa2226 0
[pincfg]
0x16 0x21211010
0x19 0x21a11010Then configure the kernel module to use firmware settings by creating /etc/modprobe.d/hda-intel.conf:
options snd-hda-intel patch=x250.fw,x250.fw,x250.fwThe only number that changes with each thinkpad series is the second one under [codec] (for x250 it indeed is 0x17aa2226). For other models, that number can be found using the alsa-info.sh script, grepping for 0x17aa.

Thank you for your reply.
This solutions isn't working out for me. Are you using Thinkpad Dock as well?
