Hopefully Peter will pick it up for the Tegra clock tree soon. Now I have the same results as Thierry; speaker-test looks like it should be working, yet I don't hear any audio from the monitor.

I am using: git://github.com/swarren/linux-tegra.git tegra_dev You might also need the latest version of my github U-Boot to use my github kernel, since I fiddle with the pinmux initialization a bit: git://github.com/swarren/u-boot.git tegra_dev -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
