Does manually disabling audio on 3.13 break things? E.g., set radeon.audio=0 on the kernel command line in grub.
No, that doesn't seem to change anything. GDM still works, no errors in logs. alsamixer still displays an "HDA ATI HDMI" card.
Am I doing it wrong? % cat /proc/cmdline initrd=\initramfs-linux.img root=UUID=f76fdeca-b4f3-49f7-891e-910c1c17b1f8 rw radeon.audio=0
