Vasiliy could you please have a look if we have at least some devices to test?

I know of T440 so far.

Also [AMD/ATI] Cape Verde/Pitcairn HDMI Audio [Radeon HD 7700/7800 Series] is questionable as this device is not available anymore, right?

Comment 4 Vasiliy Sharapov 2015-10-14 17:58:33 UTC
Confirmed on a T430.
