Audio from the chroot will now be forwarded to CRAS (Chromium OS audio server),
through an ALSA plugin.

Future Chromium OS upgrades may break compatibility with the installed version
of CRAS. Should this happen, simply update your chroot.

You can flip through your running chroot desktops and Chromium OS by hitting
Ctrl+Alt+Shift+Back and Ctrl+Alt+Shift+Forward.

You can start GNOME via the startgnome host command: sudo startgnome

Unmounting /mnt/stateful_partition/crouton/chroots/xenial...
Done! You can enter the chroot using enter-chroot.
