I'm trying to program my direct tv remote RC64 to control the volume of my sony STR-DE597 surround sound reciever. Using the codes on direct tvs site i can get the unit to turn off and on but nothing else. Any hints? I've gone through the setup several times with no luck. thanks in advance for your help.

The volume keys NEVER work initially with ANY audio code in the directv white remotes, reason is the volume keys won't work at all without a tv code programmed to the tv device. once there is a tv code its volume is now in the way, but that can be remedied:

So with tv code in, a code that powers the sony porogrammed in, probably 31758, to get the volume:

1. av1 or av2
2. press and hold MUTE & SELECT, wait for two blinks, release
3. enter 9 9 3
4. press VOL DOWN

if you want the sony volume in ALL devices do the following instead:

1. av1 or av2
2. press and hold MUTE & SELECT, wait for two blinks, release
3. enter 9 9 3
4. press SELECT

Perfect! Thank you very much.
