All I know is that radeon audio worked fine in 3.x and stopped working in 4.x Where stopped working means fairly recognizable audio which sounds mixed with white noise. I doubt I can bisect. The screen it uses is in almost constant use.... In order for the fb to be there from boot, the firmware is all compiled into the kernels via CONFIG_EXTRA_FIRMWARE. Given that, with 4.9, the audio has exactly the same problem with amdgpu as with radeon, I suspect the actual problem is in the firmware. If so, and since I do not have whatever firmware files were installed back when I compiled the 3. kernels, I doubt bisecting the kernel would help. -JimC -- James Cloos <cloos@xxxxxxxxxxx> OpenPGP: 0x997A9F17ED7DAEA6 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
