Nope, no news on the binary blob.
Amdgpu/radeon HDMI/DP audio still requires DAL which isn't accepted by the kernel maintainers. Theoretically you could build your own kernel with it.
Linux 4.12 seems to have some news on DAL/DC which means it might land in 4.13: https://www.phoronix.com/scan.php?pa...y-Feature-Look
- Most notable to the DRM tree for Linux 4.12 is initial Radeon RX Vega support. But before getting too excited, this support for the next-generation AMD Vega GPU lacks any physical display capabilities as the DC (formerly DAL) code isn't landing for Linux 4.12. So when Vega launches next month, Linux gamers and others will still need to use the AMDGPU-PRO hybrid driver or build your own out-of-tree kernel build to get Vega working with display capabilities. Hopefully DC will finally land for Linux 4.13 to allow Vega display, HDMI/DP audio, open the door for FreeSync, etc
