I'll quadruple check all of my audio connections and the amp (Outlaw 7500) tonight but thus far the Anthem seems to be the likely culprit. Occasionally it has worked flawlessly. Other times I'd get nothing for a while, switch inputs multiple times, and eventually get audio. Most times it sits silent with a little static emanating from the speakers. Sometimes there's a soft pop/tick that seems to go from one speaker to the next around the room.
Connections are few - satellite box and blu-ray player via HDMI, Wii via analog, and a Squeezebox via digital coax. All have worked / failed to work at some point, along with the FM tuner. These last couple of days have been a roller-coaster of sulking, anger, and frustration which has led to an unorganized process of checking/rechecking wiring, switching inputs, powering off/on, and tweaking setup options. Any suggestions for things to try tonight? I'll keep a log of everything I try and the results. Or I might say screw it and drink heavily and attack it on Saturday instead...
Well first of all, you should already be working the problem with Anthem tech support. Diagnosing stuff like this often goes more swiftly with someone on the phone or with direct email exchange.
Whenever weird things like this start happening the thing to do is simplify your setup and re-check the basics.
(By the way, your comment about static from the speakers makes me suspect you may have a "ground loop" -- interference coming into your system. A common culprit is an improperly installed cable or satellite TV feed, so try disconnecting that at the wall and see if the noise from the speakers goes away. The speakers should be absolutely silent when there is no audio playing.)
Pick one source device for testing -- I recommend you use a Blu-ray player, not a TV program feed -- and disconnect the others for now. Recheck all of your cables to make sure they are properly connected in the correct sockets. A common problem with new installations is that the HDMI plugs -- which are only friction fit -- work a bit loose in the sockets under the weight of the cable or just by being knocked about as you check stuff. They need to be fully inserted straight into the sockets with nothing tugging them in any direction. Check both ends of EVERY HDMI cable -- both inputs and output to your display.
Next see if you can bring up the video images internally generated in the AVM 50v. This would include the Setup menu, and also the Video Source Adjust menu (Press and hold the "7" button on the remote). These are independent of your Source device.
If you can bring up the Video Source Adjust menu, then scroll right to the Patterns tab and down to select any of the full screen test patterns built into the AVM 50v. Do you get a proper display of those? If not then the problem is on the OUTPUT side of your AVM 50v -- either the Video Configuration or the settings in your display.
Next go to Setup > Level Calibration, change the first line "Test Mode" to Manual, and scroll down the list of speaker lines below it to make sure you are getting audio from each speaker, and only from the correct speaker. Use the Back button to shut off the test tone. If you are getting good audio from each speaker, then your physical connections to the power amp and speakers are working. If not, then, again, the problem is on the OUTPUT side of the AVM 50v. Check connections to the amp and to the speakers.
You mentioned using Trigger connections to turn on our amps. A common problem with new installations is that the plug at either end of the trigger wire is not fully inserted into the jack. NOTE: The AVM 50v Trigger sockets expect a MONO mini-jack, not a STEREO mini-jack.
Once you have verified that the OUTPUT side of the AVM 50v is working for video and audio, THEN go to your Source device.
Start simply: Set the device to output 480p (not 480i). 480p is the simplest HDMI signal. Try playing something simple like a CD disc. Do you get good audio and video?
Basically at this point you start working back up, one step at a time, to your desired configuration. See how far you can go before problems start re-appearing (if they do come back). That will give you more info as to what's happening.
