Hi all. I just built a new HTPC and am having some technical issues with the system. First, here's the system basics:
PC: HTPC with ASUS M3N78-EM mobo (with HDMI out);
Receiver: The HDMI out from the mobo runs audio and video to a Sony STRDG820 7.1 receiver;
Display: The HDMI out on the receiver then runs video to a Sharp LC-52D64U HDTV.
I'm having two problems which I do not think are exclusively related, but which I'd like to solve. I've spent hours fiddling with every setting I can find, but haven't been able to cure the problems:
1. The first problem is that when I play some movies/videos, the receiver seems unsure of the audio signal and quickly switches every 30-50 seconds between Dolby and Linear PCM. When it makes this switch the audio and video both 'flicker' for 2-3 seconds. This is an interesting problem because it does not happen all the time. For example, when I play Lord of the Rings directly from the DVD the movie plays _flawlessly_ with absolutely no problems and remains on LPCM all the way. When I play Batman Begins from DVD, or when I play Netflix Instant view, the problem surfaces.
2. The second, less annoying but still unfortunate, problem happens when the receiver is left on and the HTPC goes into standby. When I resume the HTPC the receiver does not recognize the HDMI signal ("HDMI" does not illuminate on the receiver's display) and the receiver does not relay a video signal to the HDTV.
I have installed all of the latest drivers for the mobo, chipset, etc., including NVIDIA HDMI Audio Driver.
I personally think that the problem is with the receiver's processing of the HDMI signal from the HTPC. I don't think there is anything wrong with the HTPC, but I may be assuming too much.
Any help from you guys would be appreciated.
Let me know if you need more tech specs.
