I'm still struggling with handshake issues using my HTPC (Vista 32, ATI 5450). I've at least figured out (kinda) what's up -- now I need to perfect the workaround.
Long story short -- my Samsung display needs to be up and running before I turn on the 2310, in order to get audio from the HTPC (I'm thinking maybe the PC thinks it's connected via DVI if "sees" only the 2310 at handshake). I can't program power on delays into my Harmony One (need to get a tech to do that and I'm way past phone support), so the Activity macro is out. Manually powering on the devices in the proper order is my workaround for that.
Now -- if I choose another activity first (say play a Bluray/DVD or watch TV), and all devices are ON, then
switch to the HTPC activity, I likewise have no audio. The workaround here is to:
1) reboot the PC
2) manually reseat the HDMI cable on the PC
3) power cycle the 2310.
Basically, my question is this: is there a way to force a new handshake by toggling something with the 2310, so I don't have to power cycle it (I'm worried about wear and tear, maybe needlessly ... )? Simply switching HDMI inputs doesn't work, and I haven't found any other way to accomplish this. Oh, and BTW, it doesn't matter if I have HDMI control set to the HTPC input or not -- actually setting it to that messes up the first workaround I mentioned up top).
Hopefully this all makes some sort of sense.
