Hello Daniel, I think the HDMI audio was intentionally disabled, adding "radeon.audiio=1" into the grub parameter could solve this. Or you can install the proprietary driver. ** This bug has been marked a duplicate of bug 864735 [ATI HDMI] HDMI Audio Disabled by Default (since oneiric) ** Description changed: CID: 201108-8338 There is no HDMI audio Steps: 1.
