13.04 hdmi issue

[allen4]

Hello, posting my issue here.. I really want to like 13.04, but for the sound issue. Things I have tried:
Installed the daily builds package.
Installed pulse audio control
Purged alsa and reloaded
It shows my radeon 7850 as a sound device but no sound... Also I unmuted the sound in alsamixer.
Running kernel 3.8, and after removing alsa base and reloading it, now the sound button on the top ribbon is gone, and all sound options are also gone in system sound settings, but my radeon still shows up in pulse audio control.

Please help!!

Have you tried

sudo nano /etc/default/grub

add

radeon.audio=1

to the end of

GRUB_CMDLINE_LINUX=

(between the double quotes, with a space in between)

Press control+x to save
Run

sudo update-grub

and reboot to ssee if it works.

Else, see https://bugs.launchpad.net/ubuntu/+s...x/+bug/1169984

Tried it an figured it out. Need to add radeon.audio=1 to the command line with quiet splash, not the one with the two opposing quotes.
