[Bug 1186879] Re: AMD Radeon HD 6250 No HDMI audio output with radeon driver
HDMI audio on AMD/ATI GPUs has been disabled by the upstream kernel
developers as it causes blank screens on a lot of systems.
You can re-enable HDMI audio by adding radeon.audio=1 to your GRUB
kernel boot options as described at
