Cc'ing drm.

I conclude further tests.

* Linux 2.6.35-rc2
- fbcon:radeondrmfb using "modprobe radeon modeset=1"
- sound ok
- Xorg (7.4) with 'radeonhd'
- fbcon ok, no sound in Xorg - I figure radeonhd is obsolete
- Xorg with 'radeon'
- fbcon ok, xorg ok.
There is a small breakdown when switching between fbcon and xorg

* Linux 2.6.33.5
- like 2.6.35-rc2, but had a bug that prevented radeon.ko to go into
graphics mode when initially loaded; workaround: modprobe fglrx;
rmmod fglrx; modprobe radeon modeset=1
- or fglrx, also makes sound work

- fglrx bug aside: switching from Xorg to console (either 80x25 or
radeondrmfb) makes a fugly "pop" noise, and if the target is
radeomdrmfb, display is garbled.


So I'm happy.
Conclusive questions however:

* Why is it that I am only allowed to have sound in graphics mode?

* The radeon.ko module does not have any PCI IDs defined, thus does not
get autoloaded like i915.ko. Is this intentional? It also seems
to default to modeset=0.

HDMI audio is only enabled on active outputs during modeset.

What kernel are you using? It definitely has pci ids and autoloads just fine.

Bleh. If it shows text, that seems pretty active to me.

Do you mean vga console prior to loading radeon or fb console after
loading radeon? The driver needs to be loaded. Also, the attached
monitor has to announce itself as hdmi for audio to be enabled.

It only defines PCI IDs (and gets autoloaded) if CONFIG_DRM_RADEON_KMS=y.
