Lenovo Onelink Pro Dock - No audio via Dock-HDMI

[Ray-Ven]

Sound over Laptop HDMI works, but won't work over Dock with Kernels newer than 2.16 in all ubuntu releases since trusty. Persists with latest bios (state 16.08.16) Freshinstall makes no difference.

what a shame - still not working - tried it in xenial and yakkety again

[penalvch (penalvch)]

Ray-Ven, to clarify, did you personally test the patch noted in http://www.spinics.net/lists/intel-gfx/msg68973.html and confirm it works with your hardware?

[Ray-Ven (ray-ven)]

Thank you for your answer Christopher,
no, I didn't - I think it's 4 patches which belong together - don't they?
I don't know how to apply them, but I'll try to find out.
Bios is latest though, of the Laptop and the Dock as well.

Ray

Ray-Ven, unless you have tested those patches and confirmed it fixes your problem, then this report is not confirmed a duplicate of any other.

Instructions for testing upstream patches is available via https://wiki.ubuntu.com/Kernel/KernelBisection#Testing_a_newly_released_patch_from_upstream .

I'm unable to create a patched kernel - I'd try if I could
