and it will display the version in the top part of the output. I believe the Amahi version installed for Fedora 14 is 0.9.2.
Please keep in mind that HDA integration has not been thoroughly tested with the latest Greyhole version by the Amahi team. While we do not suspect it will cause any problems, we cannot guarantee it will work flawlessly with the latest HDA platform.
