description |
I have a Lenovo ThinkPad E540 with an Intel Haswell (4th Gen) HD graphics controller connected to a OneLink Pro Dock. The Dock uses DisplayPort (DP) 1.2 MST (multi stream transport) to provide both a DP and a DVI port. My monitor is connected to the DP.
When I used kernels <= 3.16 audio worked fine, but the monitor would flicker heavily. So I installed linux-lts-vivid (3.19) which fixed the graphics problem (now I can see various DP? outputs in xrandr as opposed to one before), but there is no DP audio output to chose anymore.
I also tested the latest mainline kernel 4.1-rc8, where this bug still exists. To further investigate I got these version's kernel sources, applied 4 patches by Dave Airlie from the intel-gfx mailing list [1] and tested this build (4.1-rc8+), which fixed the problem! I can play sound over DP, the same way I can over HDMI or DP without MST.
I hope it is possible to backport these changes!
