Hi Roger,

We're both new here so I thought I'd give you a heads up.

I've been using a patch to my system for about 2 years now that does
exactly what you suggested.  It has a hold-off period of 500mS - works a
treat.  If you are interested you can find it in my patch list -
http://www.softsystem.co.uk/download/mythtv/mythbuild-CURRENT.zip
as mythpatches-0.24/mythtv-master/0201-Audio-Offload-dbase-updates...patch

I'll be creating a some dev branches in the coming weeks with many of
these tweaks.
