First, not sure this thread landed in the right forum, so moderator(s) feel free to move it, if it would be better off someplace else.
Now, to my issue. Well, this revolves one of these typical everyday issues, that is really not a big deal, but I was thinking, you know, it would still be delightful if some easy solution on it came up.
So, our main PC here at home runs music pretty much every day. The computer is sending audio over HDMI to the TV, that is connected to a 5.1 home cinema system, pushing the actual sound. Everything is fine, except for power settings kick in every ~30 minutes, or whatever it's currently set at. No, I don't want to simply disable the screen power settings, since they are often found useful.
What I do want, is as small .APK (Android application) that simply pushes some command over our LAN/WLAN here at home, lighting the screen (hence the audio) back up, not moving my *ss from the sofa. As of now, one of us have to grovel from the sofa to the workstation, move the mouse, and then go back to the sofa. This is not ideal.
I was thinking about this yesterday. I stumbled upon the classical WOL (Wake-on-LAN) thingie, sending a magic packet on UDP port 9. There are plenty of Android apps and now I can fire my computer back up from the sofa from my phone, but only if I chose to keep it in either Sleep or Hibernation mode. This is not the case here no, like I said, I simply have the screen turned of every 30 minutes.
I'm trying to think outside the box, if there are some simple method of reaching my goal here; i.e. solution through existing protocol of some kind. I'd rather not call a RDP connection just for waking my screen, so we could rule that one out. Any other ideas? Anything on-spot would be much appreciated.
