There's no way to associate recording profiles to capture cards--they're
associated with specific recording rules.
Therefore, your only option is to either live with it or run some kind
of script after MythTV starts recording to set the volume appropriately
on your capture cards. You can either use a script spawned by the
external channel change script or one spawned by a Recording Started
system event, and have it sleep for a while (5, 10 or 20s or ...) then
adjust the volume. You probably want to have MythTV set the "lower"
volume properly and then have the script increase the volume on the
quieter cards so that you're not blown out of the chair by the loud
volume for the first 20s.
