[Bug 1467190] Re: No audio over DisplayPort MST
I have an HP 8740w that has the same problem on Xenial LTS (16.04.3) with the HWE (4.10) kernel, although I have also tested it on the 4.4 generic kernel with the same results. The sound configuration shows only analog audio possibilities (5, IIRC), whereas on my older HP (stolen) and my broken ASUS (when it was working) both showed 7 or more options, including several digital options, many of which worked just fine through the HDMI TV at the other end. I have used four different DP-HDMI adapters, 3 which were non-active and the newest one, which is an active adapter from SIIG - no digital sound at all. What this does is it makes it impossible to get, e.g., movie sound on the HDMI TV set, which means I am stuck with the notebook speakers - they're nice, but it's just not the same, or a plug-in set, which should never be necessary when the hardware supports the right kind of sound. If I put the Windows hard drive the system cam with back into the notebook and run from there, the sound is just fine. That was strictly for test purposes - I never use Windows if I can avoid it, which is better than 99% of the time. I would really appreciate a fix. I can attach whatever information you need on request.

@Ray-Ven I don't have the files lying around anymore. I will try to do it again sometime. But until I get to it, you could really do it yourself if you have a little experience with the terminal. I used git as per the instructions on e.g. http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.9/.

Thanks! Indeed I updated to the latest BIOS version (no change). As you can see (with my still identical hardware) the bug persists in ubuntu 16.04.1 and kernel 4.4 (4.4.0-57.58 to be exact). I also just tested the latest mainline kernel release 4.9 (4.9.0-040900-generic) which did not fix it! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1467190 Title: No audio over DisplayPort MST To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1467190/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

apport information ** Tags added: apport-collected xenial ** Description changed: 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!
