HDMI audio disabled by default for radeon video driver

[jape41]

I wasted quite a bit of time trying to get HDMI audio configured in mythTV only to discover that hdmi audio is not enabled by default in recent kernels.

My onboard video chipset is the radeon HD3200.

I was doing a fresh install using mythbuntu-12.04.3-desktop-amd64.iso

Since mythbuntu key audience is HTPC, hdmi audio should be enabled by default, or prompt the user to enable it during setup. ie radeon.audio=1 should be set

go to:
/etc/default/grub

and change

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1"

then:

sudo update-grub

We really do appreciate you opening this ticket to help improve Mythbuntu, but it needs to be closed for a number of reasons. The biggest one is that upstream has moved on to a new version and believes this to be fixed. Could you please verify if this issue still exists in the latest version?

Please do not let the closing of this ticket dissuade you from opening a new ticket if this (or any other) problem occurs with the newer versions.
