After a week or two of use, the sound on my DH77EB has stopped working. I noticed it when I plugged headphones into the front jack and the message "You just plugged a device into the audio jack" would keep popping up over and over. Now, without anything plugged into the front jack, the Realtek Audio Panel shows that both a headphone and mic are plugged in. The line-out for the speaker is plugged in, although no sound comes from it.
If I plug in my headset, I don't hear anything from it, but additionally the center subwoofer line becomes active even though nothing is plugged in there.
Any ideas? I've re-installed the system, disabled the front audio port, removed the font panel connector but to no avail.audio
