--- Comment #12 from Michal Krenek (Mikos) m.krenek@gmail.com 2010-06-22 17:26:39 --- Alex Deucher: I have tried booting with radeon.audio=0 (and also setting "options radeon audio=0" in modprobe.conf), but it doesn't seems to work, I still see "card 1: HDMI [HDA ATI HDMI], device 3: ATI HDMI [ATI HDMI]" in aplay -l output (on the other hand, "[drm] Enabling audio support" line is now missing in dmesg output, so maybe it really is disabled?).
Anyway I have tried HDMI with radeon.audio=0 and after activating HDMI output with xrandr, it didn't lock up for the first time (when I tried clone mode) but TV stayed black and displayed "unknown video format". I have tried several resolutions without success and when I tried dual screen setup (instead of clone mode) LVDS finally went also black and lock up. But I could still get into system over SSH and there is still that "[drm:r600_audio_set_clock] *ERROR* Unsupported encoder type 0x19" line in dmesg.
This was tested on drm-radeon-testing kernel. Unfortunately I didn't have time to compile new kernel with that "disable frac fb dividers for rs6xx" patch to try it out yet.
