As far as I can tell from the docs, that > just means there are no GPIOs. I don't think it's GPIO. Which graphic chip is on AppleTV? if it's Nvidia, we have little chance. But, if it's an Intel on-board, it might work. Some people reported HDMI works in a certain level (not perfectly at all though). Anyway, you can try my latest tree available at git.kernel.org git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-unstable-2.6.git and git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/alsa-driver-build-unstable.git The former is the kernel tree and the latter is alsa-driver build tree. Run utils/setup-alsa-kernel KERNEL_DIR on alsa-driver tree to set up the build with sound-unstable kernel git tree (see INSTALL for details). The ready-to-be-built snapshot tarball is available at http://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/ Takashi > > Ben > > On 9 Mar 2008, at 00:10, Ben Firshman wrote: > > > This is on 1.0.16.
