    We're discussing here about ways to prevent windows from disconnecting HDMI peripherals, in a very short review.

    No. I didnt' try it. But how an app that just sends a stream to the AVR to prevent mode switching in the AVR could help me? My problem is that AVR dissapears from windows when switched off. It's so simple, but complicated at the same time... :(

    As I said before, it solved MY problems, no mather which driver I use (realtek or amd). I'm just sharing my experience. My AVR dont even show on windows.
    My new setup is running windows 8 + TV modified EDID connected to my AVR + AVR Audio Guard.
    And, of course, 5 new HDMI cables v1.4 with ethernet (the major problem of ps3 losing connection/trueHD/deep color = hdmi cables)

    I found a software "solution" for not having to reboot my HTPC if I leave it on and Windows7 decides to turn my HDMI adapter off that works for NVIDIA cards (I have a GeForce GT 430).

    Would this work too? https://forums.geforce.com/default/...otplug-detection-failure-after-sleep/#3866410

    I seem to have the problem less in Windows 8 than I did in Windows 7. It still occurs sometimes mind you but now I'm on MediaPortal I think I'll just go read about how to get a bat file into the homescreen and tell my wife to run it if the sound isn't working.

    I took the approach of rebooting the HTPC when woke from sleep. I keep the clients as lean as possible and they are on a SSD so boot times are quick. It saves me power and HDMI handshake issues.

    I'm running 1.6 final now, GT430 (with NVIDIA Universal GeForce driver 331.65), and I can't remember having the HDMI issues (audio driver disappear)for quite some time now. I often put my HTPC to sleep, then turn off my AVR, then the TV. Or sometimes (If I start a download queue in Online Videos or something) I just leave the HTPC on, turn the TV and receiver back on (doesn't seem to matter which order even) and when I switch to the HDMI input on my TV, MediaPortal is waiting for me full screen as expected, not re-sized by Windows7.

    This might be because I'm not running my HTPC in 1080p anymore, but I'm using NVIDIA's re-size option to fix the overscan of my TV, I'm not sure, but I do recall having less of these issues after using this. Maybe Windows has to honor the size settings I've used? I'm gonna put music on, turn my TV off and see what happens.

    Edit: If I turn the TV off while playing music, MediaPortal crashes (with or without the option "Stop playback when the audio renderer is removed" ticked)

    I still had the problem all the time. I finally got around to trying the HDMI pin 19 trick and... the problem is COMPLETELY solved. It doesn't matter what happens, the audio device doesn't disappear anymore. Wonderful. Thanks to whoever posted it here in the thread.

    The only problem is that it's quite hard to actually cut a piece of tape that small, let alone stick it in the right spot! I don't dare remove the plug from my amp I must say!

    Is there anyway to physically remove the pin? Small pliers or something? I'd rather have it permanently removed than have the tape there now that I've confirmed it working

    For the pin 19 trick. is there a HDMI connector plug which you can use? One could customize a plug to tear out one pin. on one side.
    Just thinking out loud.

    My experience with pin 19 and resume from standby is...
    If i resume with the avr powered off then hdmi audio device is defined as not connected. Turning on the avr now doesnt help alone. Windows doesnt detect it. If i do a devcon rescan then it detects that the avr is on.

    The same result happens if the avr is turned on before the htpc but in the scenario where the avr is turned on to the wrong audio input..like cd in etc.

    Turning it to the right audio input doesnt make Windows detect it. Devcon rescan fixes it.

    The one thing that makes it 100% bulletproof is where the avr is turned on automatically when the htpc is turned on and when the avr is on the same correct audio input always.
    U can buy a cheap master slave power distribution socket where u can have the htpc turn on external gear like the avr.

    This particular setup seema to work with a yamaha avr.

    I am still on 1.22 but I had a thought that MediaPortal did not like starting up without a Audio Device available in Windows, even if you later turn on the TV (HDMI audio device becomes available) and play the TV content.

    Hi CyberSimian, I have concluded the same thing. Disabled "Show last active module when resuming" and go to TV after starting up in the Home screen. Would be nice if it could start on TV (if that's where MP was when put to sleep), just like my older Panasonic PVR. But this workaround is reasonable. I will add that sometimes, even...

    Hello!!! I use a handy app called catchin' sync to roughly check the AV sync of audio/video on my HTPC/TV. It's not as accurate as a dedicated opto-electronic calibrator but it's more than adequate for this application and much better than trying to do things by eye (even when the lack of sync is massively obvious, subjective...
