Fabrizio Gennari, the WORKAROUND documented in https://help.ubuntu.com/community/RadeonDriver#HDMI_Audio would be the current method of enablement going forward due to commit 108dc8e8b44a4c64ac53676cc05f6234340ccd4a so further testing at this point is unnecessary. I'll mark this Triaged for now, and we can keep an eye on upstream progress towards this chipset:

    drm/radeon: rework audio option
    In 3.12 I changed audio to be enabled by default, but you still had to turn it on via xrandr. This was confusing to users so change it to minic the previous behavior:
    - audio option is set to -1 (auto) by default which is the current 3.12 behavior (audio is enabled but requires xrandr to turn it on).
    - if audio = 1, the audio is enabled without needing to mess with xrandr (previous behavior)
    - audio = 0 disables audio
    It retains the new feature of allowing the user to enable audio on the fly with xrandr, but turns audio on automatically if radeon.audio=1 is set which is what most users expect.
