whynot - The audio strength signal doesn't work on the HR2x line of DVRs. For some reason, DIRECTV never enabled the sound output. No one here knows why, so rest assured that there's nothing else to try ... you just have to rely on the on screen signal levels if you're manually aligning your dish.
(There's also hand-held equipment to report signal strength aligning dishes, but I don't have much info to share about that.)
