The new issue has been fixed in kernel 3.8.0-22.33 which is available in
raring-updates. Adding radeon.audio=1 to the GRUB boot options will
once again enable HDMI audio on AMD/ATI Radeon hardware.

CORRECTION: Contrary to what I wrote in comment #37, the Ubuntu
3.8.0-17-generic kernel DOES support HDMI audio in Ubuntu 13.04.
However, at least for me, HDMI audio continues not to work with the
Ubuntu 3.8.0-18-generic kernel or with the Ubuntu 3.8.0-19-generic
kernel.
So the bug seems to have
The same problem seems to be getting some more traction over at bug
#1169761. They have also identified the same regression window that you
have.

to work using a kernel from an earlier daily release. In particular, so

The same here, on Ubuntu 13.04 Gnome Remix: 2 weeks ago I had audio over

Hmm. That's strange. I've updated two different installations of
Ubuntu 13.04, and I lost HDMI audio for both of them. I'll update
again in a few days just to see if the problem corrects itself. If not
self-correcting, I'll try a clean install from the final release in a

I've been testing Ubuntu 13.04 with an AMD Radeon HD 6670 graphics card
attached to a big screen TV via HDMI. Until very recently (within the
last week or so), adding radeon.audio=1 to my GRUB boot options had
allowed HDMI audio to work flawlessly.
But after a recent update to Ubuntu 13.04, the

After installing Ubuntu 12.10 on a system with a ATI Radeon HD 4650

So, basically, if radeon.audio=1 is added manually, HDMI audio works

Title:
HDMI: no sound, video
HDMI audio was 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
boot options. There are reports on the Phoronix forums that this also
fixes the fast video playback problem.
