I haven't paid as close attention to Xorg issues sine the stroke last year, and I hadn't needed to reboot the box in the living room in several months.
When I did need to, I found that hdmi audio was unlistenable. It sounded like it was mixed witht white noise.
If I boot vmlinuz-3.19.0 is works fine. I had compiled 4.1.0 and 4.5.0, as well as its current default kernel, 4.9.0 (all from Linus' git). All of those 4. kernels show the crappy audio.
In 4.9 I then tried switching to amdgpu. That did not help.
The box has a Kaveri apu (ChipID 0x1313).
Firmware is from linux-firmware.git and is compiled into the kernel via CONFIG_EXTRA_FIRMWARE.
With radeon the kernel command line has: radeon.modeset=1 radeon.audio=1 With amdgpu I switched to: amdgpu.audio=1 amdgpu.exp_hw_support=1
Any thoughs on where to look?
I find it hard to believe that a bug like this could persist for so long.
amdgpu doesn't yet support hdmi audio. No idea about what broke for radeon, bisecting is probably going to be the most effective way forward (since 3.19->4.0 is so long ago no one will remember what happened back then). -Daniel
