I recently hooked up my HTPC to my ONKYO AV receiver and I'm having a small problem with the audio. I can play music/ watch movies and hear sound no problem. Usually when sound is being output from my receiver, I can see some light one the receiver illuminate to tell me that it is receiving PCM audio... or DTS if I'm watching a blu-ray, etc.
However, if there is no sound being output over the HDMI, the receiver seems to "lose" the connection and the lights don't show up. As soon as there is sound again, the lights will come back on, but it usually clips a small amount of audio. For example, if the computer is sitting idle and I launch windows media center, the first half second or so of audio that usually plays when you start up media center is cut off. Also, if I'm playing on pokerstars, where the sound is very intermittent, like usually when someone bets or folds, I almost get no sound. However, if I play an mp3 in the background at a low volume level, I can hear all of the sounds from pokerstars.
Is there some way to force my receiver or my HTPC to maintain a connection and not drop out? or maybe increase the "idle" time. It's rather annoying to not hear anything come out of the speakers when I can see the volume level meter in my mixer jumping up when there should be sound.
I did a small amount of looking through the owners manual for my ONKYO receiver and it mentioned something about specifying the digital input type. It is currently set to "auto" meaning that if some DTS signal is being passed through it will recognize it and decode it properly. I tried switching it to PCM, just to see if that had an effect, but it did not
